Chapter 3 Installing a Cisco 7500 Series Router

Installing the Cisco 7507 and Cisco 7507-MX

You can install interface processors (as shown in the following figure) in any of the five interface

processor slots, which are numbered 0 and 1, and 4 through 6, from left to right when viewing the chassis

from the rear. (See Figure 1-5.) Slot 2 or slot 3 contains the RSP, which is a required system component.

Caution To prevent overheating internal components, always install fillers in empty slots to maintain the proper

flow of cooling air across the cards. To prevent ESD damage, handle processor modules by the handles

and carrier edges only.

Figure 3-8 illustrates the procedure for removing and replacing processor modules in the Cisco 7507 and

Cisco 7507-MX.

Note In a Cisco 7507 or Cisco 7507-MX that has the high system availability (HSA) feature enabled and an

RSP2 configured as the system slave, online insertion and removal of any interface processor in either

CyBus might cause the slave RSP2 to reboot with a bus error or a processor memory parity error. The

master RSP will recover from this event and issue a “cBus Complex Restart” message. (Cisco 7507 or

Cisco 7507-MX systems that are configured with an RSP4 as the system slave are not affected and do

not experience this problem.) The RSP8 only supports the HSA feature when used with another RSP8.

If you have a Cisco 7507 or Cisco 7507-MX with an RSP2 configured as the system slave, we strongly

recommend that you use the following procedure to remove and replace an interface processor:

Step 1 Remove the slave RSP2 (also called a processor module) using the appropriate procedure in Figure 3-8.

Step 2 Wait 15 seconds.

Step 3 Remove and replace the interface processor (also called a processor module) using the procedures in

Figure 3-8.

Step 4 Wait 15 seconds.

Step 5 Reinsert the slave RSP2 using the appropriate procedure in Figure 3-8.
