The Cisco 7507 has seven slots: slots 2 and 3 for the Route Switch Processors (RSPs), and slots 0, 1, 4, 5, and 6 for the interface processors. There are bays for up to two AC-input or DC-input power supplies. One power supply is shipped as standard equipment; a second power supply is optional. A second (optional) power supply allows load sharing and increased system availability.
Note For detailed hardware installation instructions and safety guidelines, refer to the Cisco 7500 Series Router Installation and Configuration Guide, Site Preparation and Safety Guide, and the Cisco 7500 Regulatory Compliance and Safety Guide.
 | Warning Only trained and qualified personnel should install, replace, or service this equipment. |
Step 2 Ensure the power service at the site is suitable for the router you are installing.
Step 3 Check the packing slip to ensure that all the proper components are present.
Step 4 Confirm that you have the required tools and parts:
For interface modules (optional):
 | Caution Two people are required to perform this step. Avoid sudden twists or moves to prevent injury. |
Step 2 Ensure that you have at least 3 or 4 feet (0.91 to 1.22 m) of clearance around the rear of the chassis to install power supplies and perform maintenance on the chassis.
Step 3 Proceed to the "Install Interface Processors, Fillers, VIPs, or RSPs" section.
To rack-mount a Cisco 7507 router, perform the following steps:
Step 2 Secure the spanner bars.
Step 3 Attach the chassis ears.
Step 4 Mount the chassis.
Note The distance between the inner edges of the left and right rack-mounting posts must be at least 17.72 inches (45.088 cm), and the distance between the holes in the mounting posts must be 18.31 inches (46.5 cm) (+ .063 inches or .16 cm).
Step 2 Align the mounting holes in the bracket with those in the rack post.
Step 3 Support the bracket with one hand, and use the other hand to insert a 10-32 x 5/8-inch LG Phillips pan-head screw through the bottom mounting hole on the front of the bracket and into the rack post.
Step 4 Secure the top of the bracket to the rack with two pan-head screws. Finger-tighten the screws.
Step 5 Push the brackets as far apart as possible before using a Number 2 Phillips screwdriver to tighten the screws.
Step 6 Adjust the brackets if the distance between them is less than 17.5 inches (45.45 cm).
Step 7 Repeat Step 3 through Step 6 for the remaining bracket. Use a level or tape measure to ensure that the two brackets are level in the rack.
Step 2 Remove the tape that secures the spanner bar on the left bracket, and swing the bar down (see A) over the anchor screw on the opposite bracket.
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 Repeat Step 1 through Step 3 to fasten the remaining spanner bar to its anchor screw. (See C.)
Step 5 Push the brackets as far apart as possible before tightening the screws.
Step 6 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. (See B.)
Step 7 Adjust the brackets if the distance between them is less than 17.5 inches (44.45 cm).
Step 2 Use two M4 x 10-mm LG Phillips flat-head screws to secure each ear to the chassis.
| Warning Two people are required to perform this step. |
Step 2 Slide the chassis back into the rack along the ledges.
Step 3 To remove a chassis foot, use a 1/4-inch flat-blade screwdriver or insert a 7/16-inch open-end wrench between the underside of the chassis and the foot.
Step 4 Turn the foot counterclockwise to loosen it until the foot drops out of the chassis.
Step 5 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 LG Phillips pan-head screws.
The Route Switch Processor (RSP) comes uninstalled with your Cisco 7507 router, but is a required system component. Install the RSPs in the slot 2 or slot 3, and install any interface processors, fillers, or Versatile Interface Processors (VIPs) in slots 0, 1, 4, 5, and 6 (optional).
Step 2 Place the interface processor, filler, VIP, or RSP in the slot and align the guide on the carrier with the groove in the slot.
Step 3 Carefully slide the interface processor, filler, VIP, or RSP into the slot until the faceplate makes contact with the ejector levers.
Step 4 Use the thumb and forefinger of each hand to push the ejector lever flat against the interface processor, filler, VIP, or RSP.
Step 5 Use a screwdriver to tighten the captive installation screws.
Step 6 Repeat Step 1 through Step 5 to install any additional interface processors, fillers, VIPs, or RSPs.
Step 7 To check an RSP installation, refer to the "Check the RSP Installation" section, and refer to the "Check the Interface Processor or VIP Installation" section to check the interface processor or VIP installation.
This procedure applies to AC-input and DC-input power supplies, with differences clearly noted. Do not mix AC-input and DC-input power supplies in the same chassis. Install the first power supply in the lower power supply bay and the second, if any, in the upper bay. In systems with dual power supplies and separate available power sources, connect each power supply to separate input lines—the second power source will likely be available during a failure.
For DC-input power supplies, turn off the circuit breaker to which you will connect power, and tape the breaker switch to the off position.
Step 2 Hold the power supply by the handle and place your other hand underneath it.
| Caution Use two hands to remove and install power supplies. |
Step 3 Place the power supply inside the bay, and align it to go straight into the bay.
Step 4 Push the power supply back into the bay until its front panel is flush with the chassis rear panel.
Step 5 Use a screwdriver to tighten the captive installation screw on the top of the power supply.
Note For DC-input power supplies, refer to the "Install the DC-Input Power Supply" section on to complete this procedure.
Step 6 Push the cable retention clip away from the power supply receptacle, and push the power cable in until the cable retention clip snaps into place.
Step 7 Connect the opposite end of the power cable to an appropriate power source.
Step 8 Repeat Step 1 through Step 7 to install the second power supply (optional).
Step 2 Lift and remove the terminal block cover.
Step 3 Wire the DC power supply using the appropriate lugs at the wiring end.
Note The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). The ground wire should always be connected first and disconnected last.
Step 4 Attach two nylon ties around the cable and the metal bracket for strain relief.
Step 5 Install the terminal block cover over the terminal block, and tighten the captive installation screws. Do not overtighten screws.
Step 6 Connect the opposite end of the DC-input cable to the DC power source.
Step 7 Remove the tape from the circuit breaker and turn the circuit breaker to the on position.
Step 8 Repeat Step 1 through Step 7 to install a second DC-input power supply, if any.
The system console port on the RSP is a DB-25 receptacle DCE port for connecting a data terminal, which allows you to configure and manage the system. The console port is labeled Console.
Step 2 Check your terminal's documentation to determine the baud rate of the terminal you will be using.
Step 3 Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600, 8N2).
The auxiliary port on the RSP is an ETA/TIA DTE DB-25 plug to which you can attach external equipment in order to access the router from the network. The port is located next to the console port on the RSP and is labeled AUX.
Step 2 Check your terminal's documentation to determine the baud rate of the terminal.
Step 3 Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600, 8N2).
The console and auxiliary Y-cables allow you to simultaneously connect the console or auxiliary ports on two RSP2s, RSP4s, or RSP8s, to a single console terminal, or external auxiliary device. These are configured as system master and slave in slots 2 and 3 in the Cisco 7507.
Step 2 Connect one DB-25 male end of the Y-cable to an RSP or other external auxiliary device.
Step 3 Repeat Step 2 for the other RSP or other external device.
Step 2 Connect one DB-25 female end of the Y-cable to auxiliary ports on an RSP in an RSP slot.
Step 3 Repeat Step 2 for the auxiliary ports on a second RSP in an RSP slot.
Step 4 Connect the interface processors or VIPs to the external network. Refer to the appropriate processor module manual, such as the Route Switch Processor (RSP4/4+) Installation and Configuration Guide.
Step 2 Turn the system power switch to the on (|) position. The green AC (or DC) OK and fan OK LEDs on each power supply should go on. After a few seconds, the red output fail LED will turn off.
Step 3 Listen for the system blower; you should immediately hear it operating.
Step 4 Observe the normal LED indicator on the RSP. If this indicator is not on after system initialization, an error has occurred. If necessary, refer to Appendix A in the Cisco 7500 Series Installation and Configuration Guide.
Step 5 Wait until the system boot is complete before attempting to verify the status of interface processor indicators. During the boot process, the LED indicators on most of the interfaces go on and off in irregular sequence.
Step 6 Observe the LED indicators on the interface processors in your system. When the system boot is complete (a few seconds), the RSP begins to initialize the interface processors. During this initialization, the indicators on each interface processor behave differently (most flash on and off).
The enabled LED on each interface processor goes on when initialization has been completed, and the console screen displays a script and system banner similar to the following:
Step 7 Observe the system startup banner. When you start up the router for the first time, the system automatically enters the setup command facility, which determines which interfaces are installed and prompts you for configuration information for each one. On the console terminal, after the system displays the system banner and hardware configuration, you will see the following System Configuration Dialog prompt:
Many privileged-level EXEC commands are used to set operating parameters. To enter the privileged-level:
Step 2 Enter the configure terminal command to enter configuration mode:
Step 3 Enter the config-register value configuration command, where value is a hexadecimal number preceded by 0x, as in the following example:
Step 4 Press Ctrl-Z to exit configuration mode.
Step 5 Save the new settings to NVRAM. Enter the copy running-config startup-config command.
Note The new settings do not take effect until the system software is reloaded by rebooting the router.
Step 6 Enter the show version command to view the configuration register value currently in effect. The value is displayed on the last line of the screen display:
Step 7 Reboot the router, and then perform a basic configuration using:
Note Configuration register changes take effect only when the system reloads, such as when you issue a reload command from the console.
Step 8 Connect to the network using a serial (WAN) cable to the channel service unit/data service unit (CSU/DSU).
Step 9 Contact your system administrator to verify that the TCP/IP host on your network is preconfigured.
Step 10 Press Ctrl-Z to exit configuration mode.
Step 11 At the # prompt, enter the copy running-config startup-config command to save the configuration to NVRAM as follows:
This completes the procedure for performing a basic configuration using AutoInstall.
Note The router's serial (WAN) cable should not be connected to the CSU/DSU unless you are planning to use AutoInstall. If you are using the console Y-cable that shipped with your router, use either of the two DB-25 male plug ends of the Y-cable.
Step 2 Enter the enable secret password and the enable password when the following is displayed:
Step 3 Enter yes or no to accept or refuse SNMP management:
Step 4 Enter no to refuse to enable CLNS:
Step 5 Enter yes to enable routing on AppleTalk and IPX:
Step 6 Enter no to refuse to enable Vines, XNS, DECnet, or bridging:
Step 7 Enter yes or press Return to configure IP, and then select an interior routing protocol for IP, if you are using IP routing:
Step 8 At the # prompt, enter the copy running-config startup-config command to save the configuration to NVRAM as follows:
Step 2 Enter yes to enable IPX on this interface, using the IPX network number:
Step 3 Enter yes to enable AppleTalk on this interface, to configure for extended AppleTalk networks, and then enter the cable range number. Enter the zone name and any other additional zones that will be associated with your local zone:
Step 4 At the # prompt, enter the copy running-config startup-config command to save the configuration to NVRAM as follows:
Step 2 Determine which protocols you want to allow on the synchronous serial interface and enter the appropriate responses:
Step 3 Press Ctrl-Z to exit configuration mode.
Step 4 At the # prompt, enter the copy running-config startup-config command to save the configuration to NVRAM as follows:
Your Cisco 7507 router is now minimally configured and ready to use. If you want to modify the parameters after the initial configuration, use the setup command. To perform more complex configurations, use the configure command. For more information on additional interface configuration and information on more specific system configurations, refer to the Cisco 7500 Series Installation and Configuration Guide.
At the reboot, the following example appears:
Step 2 Enter the interface type slot/port command at the enable prompt to enter interface configuration mode, as follows:
Step 3 Press Ctrl-Z to exit configuration mode.
Step 4 At the # prompt, enter the copy running-config startup-config command to save the configuration to NVRAM as follows:
Your Cisco 7507 router is now minimally configured and ready to use. If you want to modify the parameters after the initial configuration, use the setup command. To perform more complex configurations, use the configure command. For more information on additional interface configuration and information on more specific system configurations, refer to the Cisco 7500 Series Installation and Configuration Guide.
A Flash memory card that ships with your Cisco 7507 contains the Cisco IOS software image to boot your router. You do not need to format it.
The RSP has two PC Card slots—slot 0 and slot 1—into which you can install a Flash memory card. In the RSP2, RSP4, and RSP8, the orientation is vertical. PC Card slot 0 is on the left and slot 1 is on the right (as shown).
Note A Flash memory card can be inserted and removed with the system power on. Both PC Card slots can be used at the same time.
Step 2 Remove the card from the slot and place it in an antistatic bag to protect it.
Step 3 Face the front panel of the RSP, and hold the Flash memory card with the connector end of the card toward the slot (see A).
Note The Flash memory card is keyed and cannot be seated the wrong way. The eject button will not pop out if the card is not properly inserted.
Step 4 Insert the card into the appropriate slot until the card completely seats in the connector at the back of the slot and the eject button pops out toward you (see B).
Note The card does not insert all the way inside the RSP; a portion of the card remains outside of the slot. Do not attempt to force the card past this point.
Flash memory cards shipped as spare parts must be formatted. Use only Intel Series 2+ Flash memory cards.
Step 2 At the erase all sectors prompt, press Enter to proceed.
Step 3 At the volume ID prompt, enter the ID name:
To upgrade to a new Cisco IOS image, copy the image file to Flash memory. Upgrade images one at a time; do not delete all known good images at one time. You cannot copy an image while the system is running from Flash memory.
Use the command copy tftp:filename [bootflash | slot0 | slot1]: filename for the copy procedure, where tftp:filename is the source of the file and [bootflash | slot0 | slot1]: filename is the destination in bootflash memory or on either of the Flash memory cards.
An example of the copy tftp:filename command follows for a file in the Flash memory card in PC Card slot 0:
Step 2 Enter the no boot system command, as follows.
Step 3 Enter the boot system flash slot0:new.image command, as follows:
Step 4 Enter the config-register 0x2102 command to enable loading an image from Flash memory:
Step 5 Press Ctrl-Z to exit configuration mode.
Step 6 Enter the copy running-config startup-config command to save the configuration to NVRAM as follows:
Step 7 Enter the reload command. When the system reloads, it will boot the image new.image from the Flash memory card in slot 0.
To enable booting from Flash memory, set configuration register bits 3, 2, 1, and 0 to a value between 2 and 15 in conjunction with the boot system flash device:filename configuration command, where device is bootflash:, slot0:, or slot1:, and filename is the name of the file from which you want to boot the system. In the following example, the Flash memory card is in slot 0.
Step 2 At the prompt, enter configuration commands, one per line.
Step 3 Press Ctrl-Z to exit configuration.
Step 4 Enter the boot system flash bootflash:slot0: filename command, as follows:
Step 5 Enter the config-register command with the value shown in the following example:
Step 6 Press Ctrl-Z to exit enable booting mode.
To remove and install an RSP, you will perform the following steps:
Note The high system availability (HSA) and high availability (HA) features are beyond the scope of this Quick Start Guide. For information on configuring your router for HSA or for HA, refer to the appropriate Route Switch Processor Installation and Configuration Guide, such as the Route Switch Processor 8 (RSP8) Installation and Configuration Guide.
Note Do not shut down the system power when removing an interface processor, VIP, or an RSP in a system configured for high availability HA. If you are removing an RSP and have only one RSP, shut down the system, but first copy the configuration file to a TFTP server. See the "Copy the Configuration File for an RSP" section. If you have a system using high system availability (HSA), shut down the system to remove the master RSP, but leave power on if you remove only the slave RSP.
Step 2 If you have a VIP4 and are using HSA with an RSP2 as the slave processor, remove the RSP2 and wait 20-30 seconds.
Step 3 Disconnect all cables from the interface processor, VIP, or RSP port adapters; unless you are only moving a carrier, then skip this step.
Step 4 Use a screwdriver to loosen the captive installation screws, as shown in A.
Step 5 Place your thumbs on both ejector levers and simultaneously pull them both outward, as shown in B.
Step 6 Grasp the interface processor, filler, VIP, or RSP handle with one hand and pull the carrier straight out of the slot, keeping your other hand under the carrier to guide it.
Step 7 Store the interface processor, VIP, or RSP in an antistatic bag.
Step 8 If you have a VIP4 and are using HSA with an RSP2 as the slave processor, wait 20-30 seconds, then reinsert the RSP2.
Step 9 Repeat Step 2 through Step 8 to remove any additional interface processors, fillers, VIPs, or RSPs.
Step 10 Perform the steps in the "Install Interface Processors, Fillers, VIPs, or RSPs" section to install an interface processor, filler, VIP, or RSP.
Step 2 Observe the RSP LEDs. While the system initializes, the CPU halt LED on the RSP stays on. It goes off when the boot process is complete. As the RSP initializes each interface processor, the status LEDs on each interface processor go on and off in irregular sequence.
Step 3 Verify that the console terminal displays the system banner and startup screen as the system restarts.
Note Boot time is approximately 1 minute for systems with one RSP and approximately 1.5 minutes for systems with two RSPs.
Step 4 Verify that all the enabled LEDs (on the interface processors) are on.
Step 5 In systems with a second RSP installed (and HSA or HA configured), use the show version command to verify that the slave (or standby) RSP is recognized by the system.
Step 6 When you have verified all the conditions in Step 1 through Step 4 (or Step 5 if you have a second RSP installed and want to use the HSA or HA features), the installation is complete.
If you replaced the RSP and saved your configuration file to a remote server before doing so, proceed to the "Retrieve the Configuration File for RSPs" section.
An error condition exists if no LEDs go on at power up or after initialization, or if the boot error or CPU halt LEDs go on and remain on. If this happens, see Appendix A in the Cisco 7500 Series Installation and Configuration Guide.
Note When a new VIP is inserted or when a VIP is moved to a new slot, the system recognizes the new interfaces, but leaves them in the shutdown state until you configure them. After the system reinitializes all interfaces, the enabled LED on the port adapters and on all interface processors, VIPs, and RSPs should go on, depending on your connections and configuration.
Step 2 Verify that the enabled LED on each port adapter goes on and remains on.
If the enabled LED on a port adapter fails to go on, the interface processor or VIP may not be fully seated in the backplane. Refer to Appendix A in the Cisco 7500 Series Installation and Configuration Guide.
Step 3 If the VIP is new, configure the new interfaces.
Step 4 If the VIP is a replacement, use the show interfaces type slot/port adapter/port or show controllers cbus command to verify the status of the interfaces.
If you replaced a VIP with a new VIP with a greater number of ports (for example, if you replaced a single-port adapter VIP with a dual-port adapter VIP), the system will recognize the interfaces on the previously configured port adapter, but will not recognize the additional port adapter interfaces. The new interfaces will remain in the shutdown state until you configure them.
Step 5 When the interfaces are up, check the activity of each interface by observing the status LEDs, which are described in the LED section of your port adapter documentation.
Refer to the appropriate Cisco IOS software documentation for the configuration options available, and for specific configuration instructions, as needed.
Before you copy (save) the running configuration to a TFTP file server, ensure the following:
Step 2 Enter the ping command followed by the name or IP address of the remote server, and then press Return to check the connection between the router and the remote host.
Step 3 Enter the show running-config command to display the currently running configuration on the terminal and ensure that the configuration information is complete and correct. If it is not, use the configure command to add or modify the existing configuration.
Step 4 Create a file on the TFTP server.
Note Before you can save a file to a TFTP server, a file must first exist on the TFTP server. Create this file. Ensure that the filename matches the filename you will copy from the router. Also, ensure that the server permissions are set so the router can copy to this file.
Step 5 Enter the copy startup-config tftp command. The EXEC command interpreter prompts you for the name or interface processor address of the remote host that is to receive the configuration file. (The prompt might include the name or address of a default file server.)
Step 6 Enter the name or IP address of the remote host. In the following example, the name of the remote server is servername:
Step 7 Enter the name of the configuration file. The default is to use the name of the router with the suffix -confg. Press Return to accept the default filename, or enter a different name for the file, then press Return. In the following example, the default is accepted:
Step 8 The system displays the instructions you entered for confirmation. If the instructions are not correct, enter n (no), and then press Return to cancel the process. To accept the instructions, press Return, or press y and then press Return. In the following example, the default is accepted:
The system displays a series of exclamation points
(! ! !) or periods (. . .) during the copy process. The !!!! and [ok] indicate that the operation was successful. A series of periods (...) and [timed out] or [failed] indicates a failure of the process.
If the display indicates that the process was successful, the copy process is complete. The configuration is stored on the remote file server.
If the display indicates that the process failed, the configuration was not saved (see the following example):
Repeat the preceding steps, or select a different remote file server and repeat the preceding steps.
After you upload the configuration file, continue with the "Remove and Install an Interface Processor, Filler, VIP, or RSP" section to install the RSP. If you are unable to copy the configuration to a remote host successfully, contact your network administrator or contact Cisco technical assistance.
Retrieve the saved configuration and copy it to NVRAM by accessing the router through a console terminal, or from a remote terminal.
Note The router runs from the default configuration in NVRAM until the previous configuration is retrieved. Passwords configured on the previous system are not valid until they are retrieved.
Step 2 Enter the ping command followed by the name or IP address of the remote server, and then press Return to check the connection between the router and the remote host.
Step 3 Enter the copy tftp startup-config command and press Return to enter the configuration mode and specify that you will configure the system from a network device (instead of from the console terminal, which is the default).
Step 4 Enter the IP address or name of the remote host (the remote TFTP server to which you originally saved the configuration file).
Step 5 Enter the name of the configuration file. The default is to use the name of the router with the suffix -confg (Router-confg in the following example). If you specified a different filename when you copied the configuration, enter the filename; otherwise, press Return to accept the default.
Step 6 Before the system reloads the new configuration file in NVRAM, it displays the instructions you entered for confirmation. If the instructions are not correct, enter n (no), and then press Return to cancel the process. To accept the instructions, press Return, or press y and then press Return. Output similar to the following appears:
The console display indicates whether or not the operation was successful. A series of exclamation points (!!!!) and [OK] (as shown in the preceding example) indicates that the operation was successful. A series of periods (. . .) and [timed out] or [failed] indicates a failure due to a network fault or an incorrect server name, address, or filename). The following is an example of a failed attempt to boot from a remote server:
If the display indicates that the process was successful, as shown in Step 6, proceed to the next step.
If the display indicates that the process failed, verify the name or IP address of the remote server and the filename, and repeat the preceding steps. If the process fails again, contact your network administrator.
Step 7 Enter the show startup-config command to confirm that the configuration file was retrieved correctly. Look at the first line for the configuration file size. Compare it with the file you retrieved from the TFTP server to confirm that it is correct. Following is an example:
Step 8 To ensure that the startup configuration file stored in NVRAM is the default running configuration file used by the system, enter the copy system:running-config nvram:startup-config command:
This completes the process for retrieving the configuration file for the RSP.
Note First remove the VIP from the chassis before removing the port adapter from the VIP. See the "Remove and Install an Interface Processor, Filler, VIP, or RSP" section for instructions.
Step 2 Grasp the handle and carefully pull it out of its slot, away from the edge connector at the rear of the slot. (See A.)
Step 3 To insert the port adapter, align the carrier between the upper and the lower edges of the port adapter slot. (See B.)
Step 4 Carefully slide the port adapter into the slot until the connector is completely seated in the connector at the rear of the port adapter slot, as shown in B.
Step 5 Install the screw in the rear of the port adapter slot on the VIP. Do not overtighten the screw. (See A.)
Step 6 Carefully slide the VIP motherboard into the interface processor slot until the connectors at the rear of the VIP are completely seated in the connectors at the rear of the interface processor slot. Use the ejector levers to seat the VIP in the interface processor slot. Tighten the captive installation screws on the VIP.
(See C.)
Redundant power supplies support online insertion and removal (OIR); if you remove one power supply, the second power supply immediately ramps up to maintain uninterrupted operation. In this case, proceed to Step 2. If you have only one power supply, you must turn off power before removing and replacing it. In this case, proceed to Step 1.
Step 2 Turn off the switch on the power supply.
Step 3 Disconnect the power cable from the power source.
Step 4 Disconnect the power cable from the power supply.
For the AC-input power supply: Lift up the cable retention clip and remove the power cable from the AC power receptacle.
For the DC-input power supply: Use a screwdriver to loosen the captive installation screws on the terminal block cover, lift the cover, use the wire cutters to cut the nylon strain-relief ties, and then remove the three power leads (remove the ground lead last) from the terminal block. See below.
Step 5 Use a screwdriver to loosen and remove the captive installation screw on the top of the power supply.
Step 6 Grasp the power supply handle with one hand and place your other hand underneath to support the bottom of the power supply.
| Warning Keep hands and fingers out of the power supply bays. High voltage is present on the power backplane when the system is operating. |
Step 7 Pull the power supply out of the bay and put it aside.
Step 8 If the power supply bay is to remain empty, install a power-supply filler plate over the opening and secure it with a mounting screw.
Step 9 Refer to the "Install Power Supplies in the Router" section to replace the power supply.
