This completes the procedure for installing the cable-management bracket.
Moving Processor Modules from the Old Chassis to the New Chassis
At the interface processor end of the chassis, slots contain the processor modules. (See Figure 1.) In
the Cisco 7513, the RSP occupies RSP slot 6 or 7. In the Cisco 7576, the RSP placed in slot 6
controls router A and the RSP in slot 7 controls router B. The remaining 11 slots support any
combination of interface processors.
Note
will transfer the existing RSP(s) and interface processors from the Cisco 7513 to the Cisco 7576. For
example, if the existing Cisco 7513 includes two RSPs utilizing the "High System Availability"
(HSA) feature, keep in mind that this configuration is not supported in the Cisco 7576. Refer to the
"Port and Slot Configuration Worksheet" on page 28 for port and slot planning assistance. In
addition, the Cisco 7500 Series Installation and Configuration Guide includes detailed information
on Cisco 7576 RSP and interface processor port assignments and usage.
Processor modules are keyed with guides on the backplane to prevent them from being fully inserted
in the wrong slot. Empty interface processor slots contain an interface processor filler (an empty
carrier) to help keep dust out of the chassis, provide electromagnetic interference (EMI) shielding,
and maintain proper air flow through the chassis interior.
Processor modules slide into the processor slots and connect directly to the backplane. The
spring-loaded ejector levers (see Figure 9) help to ensure that the bus connector on the back of the
processor module is fully seated in the backplane or fully dislodged from it. Captive installation
screws at both ends of each processor module faceplate prevent the processor from pulling away
from the backplane and support the EMI integrity of the system. Failure to use the ejector levers and
captive installation screws could result in a partial backplane connection, which can hang the system.
If you are replacing a Cisco 7513 chassis, move the interface processors to the same slot positions
in the new chassis to retain your existing configuration. When upgrading a Cisco 7513 to a Cisco
7576, it is not possible to retain the existing configuration. The lithium battery backup on the RSP
retains the system configuration in nonvolatile random-access memory (NVRAM). Therefore, if you
install interface processors in the same slot positions in the new chassis that they occupied in the old
chassis, the system and the individual interfaces should come up in their previous configuration. If
you install interface processors in different slots in the new chassis, the system will recognize the
interfaces, but will leave them in a shutdown state until you reconfigure and enable them.
18 Cisco 7513 and Cisco 7576 Chassis Replacement and Upgrade Instructions
Use a flat-blade screwdriver to loosen the two slotted screws approximately 1/8-inch.
Place the bracket over the screws (see Figure 8), and slide the bracket to the right.
Use a flat-blade screwdriver to tighten the screws.
When installing the network interface cables, route the cables up to and through the
cable-management bracket.
Route the excess cable out through either end of the bracket, coil it, and secure it to the
rack using nylon cable ties, or some other mode of attachment.
It might be necessary to bundle longer cables to avoid tangling them. Do this at the
cable-management bracket or at the rack, but leave enough slack in the cables to remove
processor modules. Change cables as required. Also, do not block the power supply air
vents with cables.
If you are upgrading a Cisco 7513 to a Cisco 7576, you need to carefully consider how you
