Chassis Replacement or Upgrade Prerequisites
•
•
When removing any cable, pull the cable out at the connector; never pull or tug on the cable itself.
For detailed descriptions of the system components, refer to the Cisco 7500 Series Installation and
Configuration Guide.
Preparing the Work Area
Although some network downtime is unavoidable while you remove the RSPs from the old chassis,
and replace them in the new chassis, you can minimize the downtime by placing the old and new
chassis close together. If your existing chassis is mounted in a rack and there is space in the same
rack or another rack close by, we recommend that you install the new, empty chassis in the rack
before moving the components. (A fully configured chassis weighs approximately 160 pounds.)
Before installing the chassis in a new rack location, ensure that routing the interface cables to the
new positions will not strain or tangle them.
You can further minimize downtime by leaving interface cables attached when you move interface
processors to the new chassis, provided that doing so will not strain the cables.
Leave network interface cables connected to the interface ports only if the following conditions are
true:
•
•
Note
before you can install the new chassis, you must disconnect all power and network interface cables.
Ensure that your new chassis allows sufficient clearance for maintenance—to remove and replace
processor modules, the blower module, and interface cables at the interface processor end, and to
access the internal components at the noninterface processor end.
Figure 4 shows the chassis footprint and the clearance required.

Ethernet interface cables use either slide-type locks or thumbscrews. Although all Ethernet
Interface Processors (EIPs) ship from the factory with slide-type locks on each port, all EIPs also
include conversion kits for replacing the slide-type locks with jackscrews to accommodate
Ethernet interface cables with thumbscrews.
Multimode, FDDI connectors use small plastic arms on two sides of the connector that act like
springs and are constrained by the inside of the connector port. To remove a multimode cable
from an FDDI Interface Processor (FIP) port, pinch the two plastic arms inward while pulling the
connector out of the port.
You are able to place the new chassis close to the existing chassis, and moving the processor
modules to the new chassis will not strain the interface cables.
The new chassis is already located in its permanent location, or you will need to move it only a
few feet into the space vacated by the old chassis when it is removed.
If these conditions are not true, for instance, if you must remove a rack-mounted chassis
