This document contains instructions for replacing the chassis interface (CI) board in the Cisco 7500 series routers: Cisco 7505, Cisco 7507, Cisco 7513, and Cisco 7576. The CI mounts directly to the front side of the backplane inside each chassis and provides the environmental monitoring (ENVM) and power supply monitoring functions for the Cisco 7500 series routers. The CI isolates the CPU and system software from chassis-specific variations. The CI attaches directly to the system backplane and is considered to be a field-replaceable unit (FRU).
Following are the functions of the CI:
 |
Warning Before working on a system that has an on/off switch, turn off the power and unplug the power cord. |
To prevent injury, you must turn off all system power before opening the chassis to access the CI. The system backplane, which is exposed when the front panels are removed, carries dangerous current levels. Opening the chassis exposes the power distribution wiring on the backplane. If the power is not shut down, the high current present on the backplane becomes a hazard. Also, removing the cover compromises the electromagnetic interference (EMI) integrity of the system. Before opening the chassis, read the section "Safety Guidelines" on page 6.
 |
Note The CI is a FRU for the Cisco 7500 series chassis; therefore, we recommend that the following procedures be performed by Cisco-certified service personnel. |
This publication contains the following sections:
This section discusses important installation prerequisites.
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement.
This section lists safety guidelines you should follow when working with any equipment that connects to electrical power or telephone wiring.
|
Warning Read the installation instructions before you connect the system to its power source. |
Follow these basic guidelines when working with any electrical equipment:
|
Warning Before working on a system that has an on/off switch, turn off the power and unplug the power cord. |
|
Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. |
|
Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. |
|
Warning This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power supply cords before servicing the unit. |
|
Note The following warning is for units with DC-input power supplies. |
|
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position. |
Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
|
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. |
|
Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. |
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, can cause complete or intermittent failures. Following are guidelines for preventing ESD damage:
 |
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms. |
Following are the tools and equipment that you will need to complete the CI replacement:
The following procedures describe how to replace the CI in the Cisco 7505. Depending on your installation, you might need to remove the Cisco 7505 from the rack in which it is installed. shows the interior of the Cisco 7505 at the front (noninterface processor end) of the chassis, with the front chassis panel removed to show the internal components.
In the Cisco 7505, the CI mounts directly to the noninterface processor side of the backplane, behind the backplane cover. (See .) A connector on the back of the CI plugs into a backplane socket, and the corners of the CI butt up against four standoffs. When the backplane cover is in place, four long phillips screws extend through the cover, the CI, and standoffs to secure the cover and the CI to the backplane. To replace the CI, you must remove the chassis cover panel and remove the fan tray, power harness cover, and backplane cover.
You must remove the fan tray to remove the backplane cover. To remove the fan tray, you need only remove a single M4 pan-head screw that anchors the fan tray to the interior chassis frame. The fan tray slides into the right side of the chassis (when viewing the chassis from the noninterface processor end).
Because the power harness cover straddles both the power supply and backplane cover, you must remove it to access the CI. The power harness cover shields the wiring harness that delivers DC power from the power supply to the backplane. A tab at the bottom of the cover fits into a slot in the chassis floor; a single phillips screw secures the top of the harness cover to the backplane cover.
The backplane cover shields the noninterface processor side of the backplane and the CI (the CI cover is integrated with the backplane cover). Fourteen phillips screws secure the four flanged sides of the cover to the interior chassis frame and, near the center of the cover, two additional screws secure the cover to two standoffs mounted to the backplane (behind the cover).
The CI standoff screws secure the backplane cover and the CI to the four CI standoffs mounted to the backplane. Removing the backplane cover exposes the entire backplane, including the CI, which remains attached to the backplane by the 96-pin connector.
The two captive slotted screws are the only fasteners on the cover panel. Five shallow tabs at the bottom edge of the panel fit into slots at the base of the chassis opening. The tabs act as a pivot point for pulling the top of the panel away from the chassis opening, and as guides to align the panel when replacing it. If the chassis cover does not seal the end of the chassis, the flow of cooling air inside the chassis can be misrouted, which can result in an overtemperature condition.
|
Warning Before working on a system that has an on/off switch, turn off the power and unplug the power cord. |
To remove and replace the chassis cover panel, follow these steps:
Step 2 Pull the top of the panel out about three inches (see ), then grasp the sides of the panel and pull it upward and away from the chassis.
Step 3 To replace the cover panel, hold the sides of the panel with both hands and tilt the top of the panel back slightly (toward you).
Step 4 Slide the guide tabs into the slots into the bottom edge of the chassis.
Step 5 Using the guides as a pivot point, push the top half of the panel back toward the chassis opening until the panel is flush with the edges of the chassis.
Step 6 Hold the top front of the panel in place, if necessary, while you tighten the two captive slotted screws with a 3/16-inch flat-blade screwdriver.
This completes the chassis cover panel removal and replacement procedure.
When viewing the chassis from the noninterface processor end, the fan tray is on the far right. (See .) A cutout in the front of the tray provides a handle for pulling the tray out of the chassis. An M4 phillips-head screw anchors a tab on the lower left side of the tray to the interior chassis frame, just below the right power supply ear. When the fan tray is fully inserted in the chassis, an edge connector on the fan control board snaps into the backplane electrical connector. The bottom of the tray is a metal runner that guides the tray along a metal track on the chassis floor. Also, a bracket on the chassis ceiling helps guide the tray into the chassis.
To replace the fan tray, follow these steps:
Step 2 To remove the chassis cover panel, follow Steps 1 and 2 in the section "Removing and Replacing the Chassis Cover Panel" on page 10.
Step 3 Attach an ESD-preventive strap between you and an unpainted surface on the chassis.
Step 4 Locate the fan tray, which is in the far right of the noninterface processor end of the chassis. (See .) On the lower left side of the fan tray, locate the tab that is anchored to the chassis frame with an M4 phillips screw.
Step 5 Use a number 2 phillips screwdriver to remove the M4 phillips screw from the tab on the fan tray. (See the cutaway view of this screw in .)
Step 6 Grasp the cutout handle in the front of the tray and pull the fan tray straight out of the chassis. (See .) After the fan control board connector frees the backplane socket, the fan tray will slide easily along the track and out of the chassis.
Step 7 Place the removed fan tray in an antistatic bag for storage or return to the factory.
Step 8 Hold the assembly in the position shown in . You can hold the handle with either your right or left hand as long as you use both hands to handle the tray. However, when inserting the tray, there is little room between the tray and the right side of the chassis. Keep the tray as straight as possible, or you may have trouble inserting it into the chassis.
|
Note Before inserting the fan tray, compare the hardware inside the chassis to that shown in . The runner on the bottom of the fan tray has to slide along in the track on the floor. At the same time, the runner on the top of the tray has to slide through the notch at the top of the chassis opening, then over the top of the card cage while staying to the left of the L-bracket on the chassis ceiling. |
Step 9 Insert the top runner of the fan tray through the notch in the top of the chassis. Continue pushing the tray into the chassis, and ensure that the bottom runner slides into the track on the floor of the chassis. If the tray hangs up, pull it back out a few inches and try pushing it back in again. If the runners seem to be catching on the brackets, push the tray slightly toward the left when inserting it again.
Step 10 Slide the tray back into the chassis, pushing it all the way in until the circuit board snaps into the backplane socket.
Step 11 Replace the M4 screw in the tab and tighten it with a number 2 phillips screwdriver. (See the cutaway view of this screw in on page 12.)
Step 12 To replace the cover panel, follow Steps 3 through 6 in the section "Removing and Replacing the Chassis Cover Panel" on page 10.
This completes the fan tray replacement.
You must remove the power harness cover to access either the power supply or the CI. A single M-3 phillips screw secures the power harness cover to the backplane cover.
|
Warning Before working on a system that has an on/off switch, turn off the power and unplug the power cord. |
To remove and replace the power harness cover, follow these steps:
Step 2 To remove the chassis cover panel, follow Steps 1 and 2 in the section "Removing and Replacing the Chassis Cover Panel" on page 10.
Step 3 Use a number 1 phillips screwdriver to remove the M-3 screw that secures the top of the harness cover to the backplane. (See the cutaway in .)
Step 4 Holding the cover with one hand, tilt the top of the cover back toward you, then pull it upward slightly so that the tab clears the slot in the chassis floor.
Step 5 When the tab clears the slot, pull the cover straight back off the harness and out of the chassis.
|
Note Move on to the required procedure, depending on the work you need to do. Then to replace the power harness and power harness cover, proceed to Step 6. |
Step 6 To replace the power harness cover, hold the cover with one hand, with the tab on the bottom and the open side facing away from you. Tilt the top of the panel back slightly (toward you).
Step 7 Insert the tab on the bottom of the cover into the slot in the chassis floor. (See .)
Step 8 While pushing the cover downward slightly to keep the bottom tab in the slot, push the top of the cover back over the harness wires until the sides are flush against the backplane cover. Ensure that all of the harness wires are under the cover.
Step 9 Insert the M-3 screw through the top of the harness cover, and use a number 1 phillips screwdriver to tighten it. (See the cutaway in .)
Step 10 To replace the cover panel, follow Steps 3 through 6 in the section "Removing and Replacing the Chassis Cover Panel" on page 10.
This completes the power harness cover removal and replacement procedures.
The backplane cover provides EMI and ground protection for the backplane, the arbiter, and the CI. To access these components, you must remove the backplane cover. You need number 1 and number 2 phillips screwdrivers to remove the backplane cover screws. Following is the procedure for removing and replacing the backplane cover.
|
Note This procedure assumes that you have already removed the chassis cover panel, the fan tray, the power harness cover, and the power harness. If not, refer to the appropriate sections in this publication to remove these items. |
Step 2 With the fan tray removed, remove the eight, 20-mm M-3 standoff screws that secure the backplane cover to the arbiter and CI standoffs. These screws are located on the face of the backplane cover. (See .)
Step 3 Remove the fifteen, 10-mm M-3 phillips that secure the backplane cover to the backplane. These screws are located around the flange of the backplane cover (two on each side, six along the top, and five along the bottom). (See .)
|
Caution To prevent loosening the backplane from the chassis, remove only those screws that secure the backplane cover to the backplane. Do not remove any adjacent screws. |
Step 4 With all screws removed, carefully guide the backplane cover out and away from the backplane, arbiter, and CI. (See .)
|
Note Depending on the replacement procedures you need to perform, refer to the appropriate sections, and then to replace the backplane cover, proceed to Step 5. |
Step 5 To replace the backplane cover, carefully guide the cover into the chassis opening over the arbiter and CI, over the guide pins on the backplane (see ), and align the screw holes in the cover with the holes on the backplane and standoffs.
Step 6 Loosely install the fifteen screws around the flange of the backplane cover. (See .) Do not tighten these screws.
Step 7 Loosely install the eight standoff screws in the face of the backplane cover. (See .)
Step 8 Verify that the cover is aligned; then tighten all screws that secure the backplane cover.
Step 9 To replace the fan tray, follow Steps 8 through 12 in the section "Removing and Replacing the Fan Tray" on page 11.
Step 10 Reattach the power harness plug to the power harness receptacle. The harness plug and backplane receptacle are polarized with notches at the top of both guide tabs (top and bottom) on the plug. Ensure that the plug is fully seated in the receptacle.
Step 11 To replace the power harness cover, follow Steps 6 through 10 in the section "Removing and Replacing the Power Harness Cover and Power Harness" on page 13.
Step 12 To replace the cover panel, follow Steps 3 through 6 in the section "Removing and Replacing the Chassis Cover Panel" on page 10.
This completes the backplane cover removal and replacement procedure.
The CI (shown in ) is a printed circuit board mounted to the noninterface processor side of the backplane, behind the backplane cover. On the back (backplane side) of the chassis are four standoffs and a connector that plugs directly into the backplane. When the backplane cover is in place, four standoff screws extend through the backplane cover, through each corner of the CI and into the standoffs, to keep both the CI and backplane cover in place.
|
Note Replace the CI only if it fails. This procedure assumes that you have already removed the chassis cover panel, the fan tray, the power harness cover, the power harness, and the backplane cover. If not, refer to the appropriate procedures in this section to remove these items. |
To remove the CI, follow these steps:
Step 2 Attach an ESD-preventive strap (your own or the one supplied with the FRU) between you and an unpainted chassis surface.
Step 3 Because you already had to remove the CI standoff screws to remove the backplane cover, the CI is held in place only by the connector that is connected to the backplane. Grasp the edges of the CI and pull it straight out at a 90-degree orientation to the backplane to disconnect the CI connector from the backplane socket. (See .) If necessary, gently rock the CI from side to side very slightly to dislodge the pins from the backplane connector.
Step 4 Place the CI in an antistatic bag.
This completes the CI removal procedure.
When you replace the CI, hold it in the orientation shown in , with the connector along the top and facing the backplane. Position the board over the backplane connector and align the four standoff holes in the corners of the board with the four standoffs.
To replace the CI, follow these steps:
Step 2 Place your fingers around the top and side edges of the CI and push it straight in toward the backplane until the connector is fully seated in the backplane socket and the standoff screw holes in the CI are aligned with the standoffs. (See .) It might be necessary to rock the connectors gently into place.
Step 3 Reconnect the power harness plug to the backplane receptacle; the plug and receptacle are polarized with notches on the guide tabs. If you have trouble making the connection, ensure that the notch is at the top on both guide tabs (top and bottom) on the plug.
Step 4 To replace the backplane cover, follow Steps 5 through 12 in the section "Removing and Replacing the Backplane Cover" on page 15.
Step 5 To replace the power harness cover, follow Steps 6 through 10 in the section "Removing and Replacing the Power Harness Cover and Power Harness" on page 13.
Step 6 To replace the fan tray, follow Steps 8 through 12 in the section "Removing and Replacing the Fan Tray" on page 11.
Step 7 To replace the chassis cover panel, follow Steps 3 through 6 in the section "Removing and Replacing the Chassis Cover Panel" on page 10.
This completes the CI replacement procedure for the Cisco 7505.
The following procedures describe how to replace the CI in the Cisco 7507. Depending on your installation, you might need to remove the Cisco 7507 from the rack in which it is installed. To replace the CI in the Cisco 7507, you must first remove the front chassis panels.
You must remove the top and bottom front chassis panels to access the chassis interior to replace the CI board.
|
Warning Before working on a system that has an on/off switch, turn off the power and unplug the power cord. |
You must remove the bottom front panel before you can remove the top front panel. The plastic bottom front panel is attached to the chassis with ball studs. The top front panel is attached to the chassis with two captive screws. The EMI shielding around the outer edge of the top front panel acts as a spring, and compresses when you push the panel into the chassis to keep the panel fitted tightly into the chassis opening.
To remove the front panels, follow these steps:
Step 2 Pull the bottom of the panel out about one inch, then place your fingers behind the sides of the panel and pull it off the chassis.
Step 3 On the top front panel, use a screwdriver to loosen the two captive screws at the bottom edge of the panel frame.
Step 4 Place one hand against the top front center of the panel to brace it. (See a.) The top of the panel acts as a pivot point when you pull the bottom out and away from the chassis.
Step 5 With your other hand, grasp the front of the panel by inserting your fingers into the opening on the underside of the bezel. (See a.)
Step 6 While pushing slightly against the top of the panel to constrain it, pivot the bottom edge of the frame outward about two inches. (See a.) Because of the tightly compressed EMI shielding, you have to use significant force to pull the bottom of the panel outward. However, be careful that you do not pull the panel more than two inches away from the chassis, or you can damage the inner bezel or LED board.
Step 7 When the bottom of the frame clears the chassis opening, keep your hands in the same positions and pull the panel downward and off the chassis. (See b.)
With front chassis panels removed, the CI board is exposed to view.
The CI (shown in ) is a printed circuit board mounted to the noninterface processor side of the backplane. On the back (backplane side) of the chassis is a connector into which the CI plugs directly into the backplane.
|
Note Replace the CI only if it fails. This procedure assumes that you have already removed the front chassis panels. If not, refer to the appropriate procedures in this section to remove these items. |
To remove the CI, follow these steps:
Step 2 Attach an ESD-preventive strap (your own or the one supplied with the FRU) between you and an unpainted chassis surface.
Step 3 Refer to and locate the CI board, which is mounted to the back of the backplane. The CI is oriented vertically, attached to the backplane via the edge connector, and is located to the right of the dual arbiter, as shown in .
Step 4 Carefully remove the CI from its backplane connector.
Step 5 Place the CI in an antistatic bag.
This completes the CI removal procedure.
When you install the new CI, hold it in the vertical orientation shown in , with the connector along the edge of the CI facing the CI backplane connector. Both CI connectors are keyed so you cannot install the CI incorrectly; however, to prevent damage to the connector pins, determine the correct connection orientation before you install the CI.
To replace the CI, follow these steps:
Step 2 Attach the CI's connector to the CI connector on the backplane via the edge connector on the CI board. If the edge connector's keys are aligned, the CI should attach to the backplane connector with a moderate amount of force. Do not force the CI into the CI connector onto the backplane connector.
This completes the CI replacement procedure for the Cisco 7507.
To replace the front panels, follow these steps:
Step 2 Two guide tabs at the top edges of the panel fit into two slots in the top edges of the chassis opening. Tilt the top of the panel back (away from you) about 30 degrees from vertical and slide the two guide tabs into the chassis slots. (See a.)
Step 3 Check the top of the panel to make sure it is lined up with the top of the chassis opening. Failure to align the panel at this point can result in equipment damage when performing the next step.
Step 4 Push the panel upward to push the tabs into the slots (see a) and pivot the bottom of the panel toward the chassis until the panel frame meets the chassis. (See b.) Maintain a steady upward pressure to keep the guide tabs in the chassis slots.
Step 5 When the panel is flush against the front of the chassis, push the panel upward until the bottom of the panel is level with the bottom of the chassis opening. (See c.)
Step 6 While holding the panel in place, place one palm against the top front center of the panel to brace it, and place the other against the lip near the bottom edge of the frame. (See d.)
Step 7 Push the panel upward and back into the chassis opening until the tabs on the front sides of the panel are flush against the front of the chassis. (See e.) You will have to use significant force to compress the EMI shielding enough to fit into the opening. If the panel resists, pull it slightly downward and make sure that the panel is lined up with the top and sides of the opening in the chassis.
Step 8 When the tabs on the front sides of the panel are flush against the sides of the chassis, tighten the two captive screws in the bottom edge of the frame.
Step 9 To replace the bottom front panel, place the ball studs on the back of the panel over the holes in the front lip of the chassis and push the panel onto the chassis until the ball studs snap into place.
This completes the CI replacement procedure for the Cisco 7507.
The following procedures describe how to replace the CI in the Cisco 7513 and Cisco 7576. Depending on your installation, you might need to remove the Cisco 7513 or Cisco 7576 from the rack in which it is installed. You must first remove the chassis covers, then remove the backplane maintenance cover, and then you can replace the CI.
|
Note The Cisco 7513 and Cisco 7576 both use the same chassis design. The instructions for removing the cover and maintenance panels are the same for both models. The Cisco 7513 includes one CI, while the Cisco 7576 includes two CIs. For specific CI procedures, refer to the "Removing and Replacing the CI" section on page 30. |
Each cover panel has four fasteners that secure the panels to the front of the chassis. The following procedures describe how to remove and replace the front cover panels on the Cisco 7513 and
Cisco 7576 chassis.
|
Warning Before working on a system that has an on/off switch, turn off the power and unplug the power cord. |
Follow these steps to remove and replace the chassis cover panel:
Step 2 Pull the top of the upper panel out about two inches, then grasp the sides and carefully pull it outward, away from the chassis. Repeat this for the bottom panel. Proceed to the section "Removing and Replacing the Backplane Maintenance Cover" on page 29.
Step 3 To replace the cover panels, align the pins on the bottom panel with the holes in the chassis and push the panel against the chassis. (See .) Repeat this for the top panel.
The backplane maintenance cover provides EMI and ground protection for the backplane, the dual arbiter, and the CI. To access these components, you must remove the backplane cover. You need a number 2 phillips screwdriver to remove the cover screws. Following is the procedure for removing and replacing the backplane maintenance cover.
|
Note This procedure assumes you have already removed the front panels. If not, refer to the appropriate procedures in this section to remove these items. |
Step 4 Attach an ESD-preventive strap between you and an unpainted chassis surface.
Step 5 Loosen the ten phillips screws that secure the cover. (See .)
Step 6 Carefully guide the cover up and away from the chassis.
|
Note Depending on the replacement procedures you need to perform, refer to the appropriate sections, and then to replace the cover, proceed to Step 7, which follows. |
Step 7 To replace the cover, carefully guide the cover over the ten screws. (See .)
Step 8 Align the cover; then tighten all ten screws that secure it to the chassis.
This completes the backplane maintenance cover removal and replacement procedure.
The CI (shown in ) provides environmental monitoring and logic functions for the
Cisco 7513 and Cisco 7576.
|
Note The Cisco 7513 and Cisco 7576 use the same CI. The Cisco 7513 includes one CI, while the Cisco 7576 includes two CIs. |
|
Note Replace the CI only if it fails. This procedure assumes you have already removed the chassis cover panels and backplane maintenance cover. If not, refer to the appropriate procedures in this section to remove these items. |
The CI is a printed circuit board mounted to the noninterface processor side of the backplane, behind the backplane maintenance cover. (See for the Cisco 7513, and Figure 19 for the Cisco 7576.) On the back of the CI (backplane side) is a connector that plugs directly into the backplane. The edge connector is for diagnostics at the factory and is not used.
|
Note When viewing the rear of the card cage, the dual arbiter and chassis interface on the right side is used with router A, and the dual arbiter and chassis interface on the left side is used with router B. |
The Cisco 7513 and Cisco 7576 use the same CI board. However, the Cisco 7576 has two CIs on its backplane. If a CI fails in the Cisco 7576, determine which CI failed and replace only the failed unit. The following steps apply to the removal of a CI board on either the Cisco 7513 or Cisco 7576:
Step 2 Attach an ESD-preventive strap between you and an unpainted chassis surface.
Step 3 The CI is held in place by a connector, which is connected to the backplane, and four screws. Use a number 1 phillips screwdriver to remove the four screws.
|
Caution Access to the CI is partially blocked by a chassis panel. (For the Cisco 7513, see , and for the Cisco 7576, see Figure 19.) Two of the screws are below this panel and two are above it. To avoid damaging CI components, do not hit the CI against the chassis panel. |
Step 4 Grasp the edges of the CI (as shown in for the Cisco 7513 and Figure 21 for the Cisco 7576) and pull it away from the backplane, up and out from behind the chassis panel. If necessary, gently rock the CI from side to side to dislodge its connector pins from the backplane connector.
Step 5 Place the CI in an antistatic bag.
This completes the CI removal procedure.
When you replace the CI, hold it as shown in (Cisco 7513) or Figure 21 (Cisco 7576). Position the board over the backplane connector and align the four standoff holes in the corners of the board with the four standoffs.
To replace the CI, follow these steps:
|
Caution Access to the CI is partially blocked by a chassis panel. Two of the screws are below this panel and two are above it. To avoid damaging CI components when you remove the CI, do not hit the CI against the chassis panel. |
Step 2 Place your fingers around the edges of the CI and carefully guide it over the chassis panel (shown cut away in for the Cisco 7513 and Figure 21 for the Cisco 7576) and push it straight in toward the backplane until the CI connector is fully seated in the backplane socket and the standoff screw holes are aligned with the standoffs. It might be necessary to rock the connectors gently into place.
Step 3 Install the four phillips screws that secure the CI and gently tighten them. Do not overtighten these screws.
Step 4 To replace the backplane maintenance cover, follow Steps 7 and 8 in the section "Removing and Replacing the Backplane Maintenance Cover" on page 29.
Step 5 To replace the chassis cover panels, refer to Step 3 in the section "Removing and Replacing the Chassis Cover Panels" on page 26.
Step 6 Reconnect the power supplies and power sources and prepare to power up the system.
This completes the CI replacement procedure in the Cisco 7513 and Cisco 7576.
After you reassemble the chassis and replace all covers, perform the following steps to verify that the new CI is installed correctly and functioning properly. These steps will also help you verify that all the components you removed or disconnected as part of this replacement procedure are returned to their previous state when all router components (except the failed CI) were operating properly.
To check the installation of the CI, follow these steps:
|
Note If the LED still remains off, and you are checking the CI installation for a Cisco 7507, Cisco 7513, or Cisco 7576, contact a service representative for further instructions. (For the TAC phone number and e-mail address, refer to the "Obtaining Technical Assistance" section on page 38.) |
Step 2 About 60 seconds after you turn the power on, verify that the NORMAL LED on the RSP goes on, which indicates that the system software booted successfully. If it does go on, proceed to Step 3. If it does not go on, do the following:
|
Note If after several attempts, the CI does not appear to be functioning properly, or if you experience trouble with the installation (for instance, if the holes in the board do not align with the backplane holes, the connectors do not mate correctly, and so forth), contact a service representative for assistance; refer to the note in the "Obtaining Technical Assistance" section. |
Step 3 If the CI is installed correctly, the router should boot up normally and you should see a banner displayed on your console similar to the following:
|
Note The Cisco (IOS software) release displayed will vary depending on your system and the Cisco IOS software release it is running. |
Step 4 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password, as follows:
Step 5 Router> enable
Step 6 Password:
Step 7
Step 8 When you enter the correct password and press Return, the system displays the privileged-mode system prompt (#) as follows:
Step 9 Router#
Step 10 Use the show environment all command to verify that the system is correctly interpreting the information it is receiving from the environmental sensors on the new CI, as follows:
|
Note The preceding example is from a Cisco 7505; the output from the Cisco 7507, Cisco 7513, and Cisco 7576 varies in format. If any other messages are presented on the console screen (error messages, and so forth), contact a service representative for assistance; see the "Obtaining Technical Assistance" section on page 38. |
This completes the CI installation check for the Cisco 7500 series chassis.

The online TAC Case Open Tool (http://www.cisco.com/tac/caseopen ) is the fastest way to open P3 and P4 cases. (Your network is minimally impaired or you require product information). After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using these recommendations, your case will be assigned to a Cisco TAC engineer.
For P1 or P2 cases (your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
Information about Cisco products, technologies, and network solutions is available from various online and printed sources.
