This document provides instructions for installing Cisco 7000 and Cisco 7507 routers in a 19-inch equipment rack. The rack-mount kit functionality is identical for both chassis. Throughout this document, the Cisco 7000 and Cisco 7507 chassis are referred to as the chassis.
The sections in this document include the following:
For complete system installation and startup procedures, refer to the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications.
This section describes the types of racks for which this rack-mounting kit is intended, and the mounting configurations that are possible with each type.
This kit is suitable for mounting the chassis in most 19-inch 2-post, 4-post, or Telco-type racks. The rack must have at least two mounting posts on which to mount the hardware, and the distance between the mounting holes in the two posts must be 18.31 inches ± .063 inches (as specified in the Electronic Industries Association (EIA)-310-C standard).
Figure 1 shows the three types of equipment racks described in this document:
 | Caution Before installing the chassis in a rack or wiring closet, read the section "Safety Guidelines" to familiarize yourself with the proper site and environmental conditions. Failure to read and follow these guidelines could result in an bodily injury or damage to the system chassis or components. This procedure requires two or more people to perform. |
Following is a summary of the installation procedures required to rack-mount the chassis. This summary is informational and is not intended to replace the actual procedures required to rack-mount the chassis.
Following is a summary of procedures:
1. Read the section "Prerequisites" starting on page 7.
2. Verify that all mounting kit hardware is available.
3. Install the brackets on the rack posts.
4. Attach the spanner bars between the brackets.
5. Attach the chassis ears to the chassis.
6. Install the chassis in the rack.
Throughout these installation procedures, refer to Figure 2, Figure 3, and Figure 4, in addition to the illustrations provided in the specific installation sections.
The mounting kit comprises two brackets, two chassis ears (each holds two captive grommets), and fasteners (screws). The brackets and ears are identical. On each bracket, the inner side has a turned ledge at the bottom to support the chassis, and shielding to provide electrical isolation between the chassis and the rack. At the front of each bracket is a flange with five mounting holes at the top and three at the bottom.
Each of the two brackets mounts to a rack post with three 10-32 x 5/8-inch, Phillips pan-head screws, which are provided. The front of each bracket attaches to the front of the rack post, and the remainder of the bracket cantilevers off the post. At the bottom of each bracket, a ledge provides a shelf for the bottom sides of the chassis.
A spanner bar on each bracket hooks into the opposite bracket to maintain an exact distance between the two brackets at both the ends attached to the rack posts and unattached ends. The spanner bars prevent the two brackets from separating. (See Figure 11 on page 19.)
Figure 2 shows the components in this mounting kit.
Each of the chassis ears attaches to a side of the chassis with two M4 x 10-mm, Phillips, flat-head screws). When the chassis is in the rack, the mounting strips on the chassis ears attach to the rack-mounting posts with four 10-32 x 5/8-inch, Phillips, pan-head screws. The ledges at the bottom of the brackets support the weight of the chassis. The ears are not weight-bearing fixtures, but prevent the chassis from sliding out of the rack horizontally.
You can attach the ears to either the front or back of the chassis, whichever end you will place at the most accessible end of the rack. For most installations, we recommend that you attach the ears to the interface processor end (rear) so that you can have access to the power supplies, processor slots, and all status LEDs.
In Telco-type installations, you can install the chassis so that the ends of the chassis are approximately centered on two posts. Figure 3 shows a typical center-mount installation.
 | Caution To maintain a safe center of gravity in Telco-type installations (shown in Figure 3), the front and rear of the chassis are approximately centered on the mounting posts. |
In a 2-post, 4-post, or Telco-type installation, you can flush-mount the chassis so that the end of the chassis is flush with the rack posts. (When mounting the non-interface processor end, the front is actually recessed 1 inch into the rack to protect the plastic front bezel.) Multiple-chassis rack kits can be stacked in a rack with little or no clearance between the brackets. You can remove the four chassis feet after mounting the chassis in the rack.
Figure 4 shows a typical flush-mount installation.
Before you begin this installation, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. This section also provides descriptions of the tools and parts you need to perform this installation, and guidelines for planning the rack location so that you can access the system components when necessary and maintain trouble-free operation.
If you are mounting a chassis that is already installed, you will need to disconnect all power and interface cables from the back of the chassis. Be sure to label the cables to avoid confusion when you reconnect them to the interface ports. The configuration worksheets provided near the end of this document can help you reconnect the cables to the correct ports if you make a copy and complete it as you disconnect cables from the chassis. (For the Cisco 7000, see Figure 16 on page 27, and for the Cisco 7507, see Figure 17 on page 28.)

Review the following guidelines to help ensure your safety and protect the equipment from damage during the installation.
| Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. (For translations of this safety warning, refer to the section "Power Disconnection Warning" on page 29.) |
| 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. (For translations of this safety warning, refer to the section "Power Supply Warning" on page 29.) |
| 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. (For translations of this safety warning, refer to the section "Power Supply Disconnection Warning" on page 30.) |
| 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. (For translations of this safety warning, refer to the section "Electric Shock Warning" on page 31.) |
When working with any electrical equipment, the following guidelines will help to ensure your safety and protect the equipment. This list does not include all potentially hazardous situations, so be alert.
The chassis weighs 76 pounds (34.5 kilograms [kg]) when empty (with no interface processors or power supplies installed) and 145 pounds (65.8 kg) with two power supplies and seven processor modules installed. The chassis is not intended to be moved frequently. Before you install the router, ensure that your site is properly prepared, so you can avoid having to move the chassis later to accommodate power sources and network connections.
Whenever you lift the chassis or any heavy object, follow these guidelines:
| Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis. (For translations of this safety warning, refer to the section "Chassis Lifting Warning" on page 32.) |
| Caution To avoid damage to power supplies and interface processors, never attempt to lift the chassis using the handles on the power supplies or the interface processors. These handles were not designed to support the weight of the chassis. |
| 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. (For translations of this safety warning, refer to the section "DC Power Disconnection Warning" on page 33.) |
Follow these basic guidelines when working with any electrical equipment:
| Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. (For translations of this safety warning, refer to the section "Lightning Activity Warning" on page 34.) |
When you replace the power supplies, remember to engage all of the safety features on each supply. The power supplies feature the following three safety interlock features:
For a complete description of the power supply, refer to the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications.
This kit is suitable for mounting the chassis in most 19-inch 2-post, 4-post, or Telco-type racks that conform to the EIA-310-C standard. The brackets, which support the chassis, cantilever off two rack posts. You can mount the chassis with either end approximately flush with the two rack posts, or, in Telco-type installations, you can center-mount the chassis. Before proceeding, review the guidelines in this section and ensure that you have planned your installation carefully to avoid hazards such as top-heavy or unbalanced racks, or cables or equipment that obstruct traffic paths or access to equipment.
Before using a particular rack, check for obstructions (such as a power strip) that could impair access to the processor modules or power supplies at the interface processor end, or to the chassis panels that provide access to the internal field replaceable units (FRUs) at the non-interface processor end of the chassis. Figure 7 shows the chassis footprint and outer dimensions, and the clearance required to remove or install FRUs.
When installing the chassis in any rack that is not secured to the floor or overhead structure, place the chassis in the lower half of the rack. A fully-configured chassis weighs 145 pounds (65.8 kg), and a shift in the weight distribution (during the installation or later as a result of disturbance to the rack) can cause the rack to fall.
Also, when installing the chassis in Telco-type racks, ensure that the rack is secured to the floor or otherwise stabilized. Center-mount the chassis if possible (and practical for your installation). Doing so places the center of gravity closest to the center of the mounting posts. Figure 8 shows the center of gravity for both center-mounted and flush-mounted installations. (The center of gravity will shift somewhat depending on which end of the chassis is positioned at the front of the rack.)
As an alternative, you can install an equipment shelf in the rack if both the rack dimensions allow the router to be secured to the shelf, and the overall configuration permits safe installation and access. If you install a customized shelf or install the router on slides, be aware of potential hazards of tip-over from an unbalanced rack.
| Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety: |
| Warning Do not use a ramp inclined at more than 10 degrees. (For translations of this safety warning, refer to the section "Ramp Warning" on page 37.) |
For complete site requirements and recommendations, refer to the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications. To help maintain trouble-free operation, consider the following precautions when planning your rack installation:
Planning a proper location for the router and the layout of your equipment rack is essential for successful system operation. Equipment placed too close together or inadequately ventilated can cause overtemperature conditions inside the chassis. In the chassis, the cooling air is drawn in through the front of the chassis, and the exhaust air is forced out the back between the interface processor faceplates.
The following guidelines are recommended to ensure a sufficient flow of cooling air to the chassis:
This section lists the tools you will need to complete this installation and the parts that are shipped as part of the rack-mount kit. Ensure that you have all the tools and parts required so that you can complete the installation without interruption.
You will need the following tools to install the mounting hardware and chassis in the rack:
You also need the following tools to replace the power supplies after mounting the chassis:
Before beginning the power supply installation, check the captive installation screws on all power supplies to determine which tools you will need.
Table 1 lists the parts that are included in the rack-mount kit. To verify that you received all the parts listed, refer to Table 1 and to Figure 2 on page 4. If any are missing, contact a service representative for assistance. (Refer to the section "Cisco Information Online" at the end of this document.)

The following sections describe the procedures for mounting the chassis in a 19-inch equipment rack with two or four mounting posts. Before proceeding, review the guidelines and recommendations in the section "Prerequisites" to protect your safety, to maintain sufficient clearance around the rack during and after the installation, and to ensure proper airflow through the chassis after the installation.
| Warning To avoid potentially serious bodily injury, this procedure requires two or more people to perform. |
Some equipment racks provide a power strip along the length of one of the rear mounting strips. If your rack has this feature, we recommend that you fasten the brackets and install the interface processor end of the chassis at the opposite side of the rack.
The two brackets are identical. The inner side of each bracket has a ledge at the bottom to support the undersides of the chassis, and shielding to provide electrical isolation between the chassis and the rack. A flange on the front of each bracket provides five mounting holes at the top, and three at the bottom. Mount the bracket with the flange in front of the rack post, and with the inner (shielded) side facing the center of the rack. The ledge should be at the bottom of the bracket. (See Figure 9.)
After you install both brackets in the rack, you must connect the spanner bar on each bracket to the opposite bracket. The spanner bars are required to prevent both ends of the brackets (at the front and rear of the rack) from separating or drifting apart. The cutouts in the brackets are to accommodate the ear brackets that attach to the chassis to the rack. (Refer to Figure 2 on page 4.)
To install the brackets in the rack, you will secure each bracket to a rack post with three 10-32 x 5/8-inch Phillips, pan-head screws. If possible (if the holes line up), use the top-most and bottom most mounting holes in the bracket. Always use the bottom mounting hole on the bracket. If the top mounting hole does not line up with a hole in the rack post, use one of the other two holes near the top of the bracket.
Follow these steps to mount each bracket to a rack post:
Step 2 Measure the distance between the holes in the mounting posts to ensure that it is 18.31 inches (± .063 inches). Make several measurements down the length of the posts to ensure they are parallel.
Step 3 Holding the first bracket in the position shown in Figure 10, place the bracket on the inner side of the rack post, with the flanged front edge of the bracket in front of the rack post.
Step 4 Slide the bracket up and down along the mounting post to align the mounting holes in the bracket with those in the rack post.
Step 5 While supporting the bracket with one hand, use the other hand to insert a 10-32 x 5/8-inch, Phillips pan-head screw through the bottom mounting hole on the front of the bracket and into the rack post. (See Figure 10.)
Step 6 Secure the top of the bracket to the rack with two pan-head screws. Finger tighten the screws.
Step 7 Repeat Steps 3 through 6 for the remaining bracket. Use a level or tape measure to ensure that the two brackets are level in the rack.
| Caution To ensure adequate space between the brackets, and to ensure the chassis stays in the rack, push the brackets as far apart as possible before tightening the screws that secure them. |
Step 8 Measure the horizontal distance between the left and right brackets. The distance must be greater than 17.5 inches for the chassis to clear the brackets; adjust as required.
To position and secure the spanner bars, proceed to the next section.
The spanner bar on each bracket hooks into the opposite bracket to maintain a fixed spacing between the two brackets. The spanner bars prevent the brackets from separating or drifting apart, particularly at the ends that are not secured to the rack. To connect the spanner bars, connect the hook at the unattached end of each spanner bar to a screw at the bottom of the opposite bracket.
Follow these steps to secure the spanner bars:
Step 2 Remove the tape that secures the spanner bar on the left bracket, and swing the bar down (see Figure 11a) over the anchor screw on the opposite bracket. (See Figure 11b.)
Step 3 If the spanner bar does not reach the opposite bracket, loosen the pan-head screws to allow more play between the brackets.
Step 4 When the first spanner bar is secured, go around to the other side of the rack and repeat Steps 1 through 3 to fasten the remaining spanner bar to its anchor screw. (See Figure 11c.)
| Caution To ensure adequate space between the brackets and a proper chassis fit, push the brackets as far apart as possible before tightening the screws that secure them and the spanner bars. |
Step 5 When both spanner bars are in place, use a number 2 Phillips screwdriver to tighten the six pan-head screws that secure the brackets to the rack-mounting posts, and the two anchor screws that secure the spanner bars. When tightening the pan-head screws on a bracket, push the bracket outward, away from the center of the rack, to ensure that the brackets remain at least 17.5 inches apart (otherwise the chassis will not fit between the brackets).
This completes the bracket installation. To install the ears on the chassis, proceed to the next section.
The ears attach directly to the chassis with four M4 x 10-mm, flat-head screws. Attach the ears to the chassis before you slide the chassis onto the brackets and back into the rack. After you slide the chassis into the rack, insert a 10-32 x 5/8-inch pan-head screw through each of the captive grommets on the ears and through the rack-mounting strips. The ears do not bear the weight of the chassis, but prevent it from walking, or sliding horizontally out of the rack.
You can mount the ears on either the front or rear of the chassis, whichever end will be in the front of the rack. We recommend that you attach them to the interface processor end of the chassis, so the power supplies and processor modules will be accessible at the front of the rack.
In most four-post racks, you will attach the ears with the mounting strip flush with the end of the chassis. Figure 4, on page 6, shows a typical flush-mount installation. In Figure 12, the example insert on the right shows how the ears attach to the chassis for flush mounting.
In some Telco-type racks, it is more practical to center-mount the chassis. To do so, flip the ears around so that the mounting strips are near the center of the side of the chassis. Figure 3, on page 5, shows a typical center-mount installation. In Figure 12, the example insert on the left shows how the ears attach to the chassis for center mounting.
Follow these steps to install the ears on the chassis:
Step 2 Use two M4 x 10-mm, flat-head Phillips screws to secure each ear to the chassis.
Proceed to the next section to install the chassis in the rack.
Two people are required to lift the chassis and complete this part of the installation. You will need to lift the chassis and slide it into the rack and onto the ledges provided by the brackets. After you push the chassis back into the rack, you will attach the ears to the rack-mounting strips to prevent the chassis from sliding forward or backward out of the rack.
Before moving the chassis, you must remove all power supplies and disconnect all power and interface cables. If you are installing a new chassis, or if you have already removed all power supplies and disconnected all interface cables, proceed to the section "Moving the Chassis into the Rack".
Before moving the chassis, you must remove all power supplies and disconnect all power and interface cables. Label the interface cables; you can use the configuration worksheet provided at the end of this document to record the correct cable connections and avoid crossing cables when you reconnect them. (For the Cisco 7000, see Figure 16 on page 27, and for the Cisco 7507, see Figure 17 on page 28.)
The power supply switch is also an interlock tab that prevents the supply from being removed when it is on. (See Figure 6 on page 11.) The interlock tab extends into a slot in the chassis when the power switch is on, and retracts into the power supply to allow removal when the switch is off.
Follow these steps to install the chassis in the rack:
Step 2 Disconnect the power cords from the source power connection first, then from the power supply receptacle. Push the cable retention clip down to free the plug, then pull the cord out of the power receptacle.
Step 3 Loosen the captive installation screw at the top of the first power supply. (See Figure 13.)
Step 4 Grasp the power supply handle and slowly pull the supply out of the bay. Keep your other hand underneath the bottom to support it. (See Figure 13.)
Step 5 Put the power supply aside.
Step 6 If a second power supply is installed, repeat steps Steps 3 through 5 to remove the second supply.
| Warning To avoid dropping the power supply and injuring yourself, use both hands to remove or install a power supply. Each power supply weights approximately 20 pounds (9.1 kg). |
Step 7 Label and disconnect all interface cables. You can make a copy of the configuration worksheet provided near the end of this document, and use it to record the correct cable connections and avoid crossing cables when you reconnect them. (For the Cisco 7000, see Figure 16 on page 27, and for the Cisco 7507, see Figure 17 on page 28.)
Step 8 On the rear of the chassis, check the ejector levers and captive installation screws on all installed interface processors and interface processor fillers to ensure that all are secure.
Proceed to the next section to move the chassis into the rack.
Two people are required to lift the chassis and insert it into the rack. The chassis weighs approximately 105 pounds (47.62 kg) when the power supplies are removed. Make sure that your path to the rack is not obstructed.
You will insert the end of the chassis that does not have the ears attached into the rack, lower it onto the two ledges on the brackets, then slide the chassis back until the ears meet the rack-mounting posts. The chassis feet are not needed on a rack-mounted chassis. You can remove the feet after you lower the chassis into the rack, but before you slide it fully back into position. The center of the foot has a slot for a screwdriver, and a 7/16-inch nut is fused to the stem of the foot. (See Figure 14.) Alternatively, you can simply leave the feet attached.
| Caution To avoid damaging power supplies and interface processors, never attempt to lift the chassis using the handles on the power supplies or the interface processors. These handles are not designed to support the weight of the chassis. Using them to lift or support the chassis can result in severe damage to the equipment and serious bodily injury. |
If you have not already done so, review the safety guidelines in the section "Lifting the Chassis Safely". Then follow these steps to install the chassis in the rack:
Step 2 With the chassis positioned so that the end with the ears attached is farthest from the rack, insert the opposite end of the chassis into the rack between the brackets, then slowly lower the chassis until it rests on the two ledges.
Step 3 Slide the chassis back into the rack along the ledges. (See Figure 15.)
Step 4 To remove a chassis foot, use a 1/4-inch flat-blade screwdriver or insert an open-end 7/16-inch wrench (or an adjustable wrench set at 7/16) between the underside of the chassis and the foot. Turn the foot clockwise (counterclockwise if the chassis is directly above you) until the foot drops out of the chassis.
Step 5 When the chassis feet are removed, continue sliding the chassis into the rack until the ears meet the front mounting posts on both sides of the rack.
Step 6 Secure each ear to the rack-mounting post with two 10-32 x 5/8-inch, Phillips pan-head screws.
This completes the procedure for moving the chassis into the rack.
If your installation requires that the chassis be electrically isolated from the rack, proceed to the next section. Otherwise, proceed to the section "Replacing Power Supplies and Interface Cables" on page 25.
The inner sides of the mounting brackets and the grommets on the chassis ears are shielded to isolate the chassis from contact with the equipment rack. If your installation requires that the chassis be electrically isolated from the rack, ensure that there are no conductive contact points between the chassis and the rack before replacing the power supplies.
Use an ohmmeter to perform the following test:
Step 2 Place one probe on an unpainted metal surface on the rack, and place the other probe on an unpainted metal surface on the chassis (such as inside the power supply bay).
Step 3 If the ohmmeter indicates an open circuit, the chassis is electrically isolated from the rack. If the ohmmeter indicates a closed circuit (0 ohms), there is at least one contact point between the chassis and the rack. Do not install the power supplies until you locate and resolve all points of contact between the chassis and the rack.
Proceed to the next section to replace the power supplies and reconnect the interface cables. If you are performing an initial installation, proceed to the appropriate installation guide.
Before proceeding, ensure that you have sufficient working space (at least three feet) behind the chassis, and that access to the power supply bays is not blocked by an equipment rack power strip or cables from other equipment. If cables from other equipment are in the way, move them aside and temporarily secure them with tie wraps before proceeding. Remember that cables that block access to the bays or processor slots might also block status LEDs from view and impede the flow of cooling air through the chassis.
Always install the first power supply in the lower power supply bay and the second, if any, in the upper bay.
Follow these steps to replace the power supplies:
Step 2 Hold the power supply by the handle and place your other hand underneath to support the bottom.(See Figure 13 on page 22.)
Step 3 Align the power supply so that it will go straight into the slot.
Step 4 Push the power supply all the way into the bay. Do not use unnecessary force; firmly push the supply back into the bay until the power supply front panel is flush with the chassis rear panel.
| Caution When inserting a power supply into the bay, do not use unnecessary force. Slamming the power supply into the bay can damage the connectors on the rear of the supply and inside the chassis. |
Step 5 Tighten the captive installation screw on the top of the power supply.
| Caution To prevent damage to the chassis components, do not turn on any power supplies until you are ready to power up the system. The interlock switch that locks the power supply in the slot also turns ON the system power. |
Step 6 If you have AC-input power supplies, plug each power cord into an AC receptacle, then push each cable retention clip up until it snaps into place around the cable connector. If you have DC-input power supplies, correctly attach the power cable leads and use the nylon cable tie for strain relief. Refer to the documentation that accompanied the DC-input power supplies.
Step 7 Repeat Steps 2 through 6 for the second power supply, if any.
Step 8 Connect each power supply cord to a separate input line.
Step 9 Reconnect all interface cables to the ports on the rear of the chassis. Use the configuration worksheet (if you recorded the cable positions when you disconnected them) to avoid crossing cables. (For the Cisco 7000, see Figure 16 on page 27, and for the Cisco 7507, see Figure 17 on page 28.)
To complete the installation, you will perform a final check of all connections, then restart the system. This procedure is not for new systems; perform this procedure only if you have already connected the network interfaces and performed the first-time startup procedures in the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications.
Follow these steps to restart the system and verify that the system restarts successfully:
Step 2 Ensure that a console terminal is connected to the RP console port and turned on, or that you have a remote login to the router from another device through a Telnet session. (You will need to check the startup banner and displays to ensure that the system restarts properly and that all the interfaces reinitialize in the proper state.)
Step 3 When you have checked all of the connection points, turn the lower power supply on by turning the power supply switch clockwise one-quarter turn. The AC power LED on the lower AC-input power supply (or the input power LED on the DC-input power supply) and the lower power LED on the front of the chassis should go on.
Step 4 Listen for the system blower. You should hear it start operating immediately.
Step 5 After the lower power supply is on, turn the upper power supply on (if one is present) for redundant power. The AC power LED on the upper AC-input power supply (or the input power LED on the DC-input power supply) and the upper power LED on the front of the chassis should go on.
Step 6 On the console terminal, verify that the console displays the system banner and that the system and all interfaces initialize successfully.
Step 7 If you try to turn on a power supply and the switch resists, the power supply probably is not fully inserted into the bay. Turn the power switch fully counterclockwise (to O), pull the power supply out of the bay about two inches, then push the power supply firmly back into the slot. Do not slam the supply into the slot; doing so can damage the connectors on the supply and the backplane. Tighten the captive installation screw before turning on the switch.
If the power supplies do not start up, or if the system or any interfaces do not initialize properly, refer to the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications for additional information and installation troubleshooting procedures.
If necessary, contact a service representative. (See the following section, "Cisco Information Online.")
Following are translations of the safety warnings that appear throughout this publication:
