Temporary Storage for Removed Processor Modules
In the Cisco 7513 and Cisco 7513-MX you can install interface processors in any of the 11 interface
processor slots, numbered 0 through 5 for CyBus 0, and 8 through 12 for CyBus 1, from left to right
when viewing the chassis from the rear. Slot 6 and slot 7 are the RSP slots and are reserved for the RSP2,
RSP4, or RSP8, which is a required system component. (See the illustration of the card cage and
processor modules in
Figure 1-11
in
Chapter 1, “Cisco 7500 Series Product Overview.”
)
The backplane of the Cisco 7576 features two routers (router A and router B) on a single backplane.
Router A consists of two CyBuses and uses interface processor slots 0 through 5, with an RSP4 (or
RSP8) in slot 6. Router B also consists of two CyBuses. It uses interface processor slots 8 through 12,
with an RSP4 (or RSP8) in slot 7. (See the illustration of the card cage and processor modules in
Figure 1-17
in
Chapter 1, “Cisco 7500 Series Product Overview.”
)
Caution
If you are configuring only one of the two routers that make up the Cisco 7576, make sure to configure
router A instead of router B. To configure router A, install an RSP4 or RSP8 in slot 6, and install
interface processors in slots 0 through 5.
Caution
To prevent the overheating of internal components, always install interface processor fillers
(MAS-7KBLANK=) and RSP fillers (MAS-RSPBLANK=) in the appropriate empty chassis slots to
maintain the proper airflow across the processor modules. To prevent ESD damage, handle processor
modules by the handles and carrier edges only.
Figure 3-14
illustrates the procedures for removing and replacing processor modules in the Cisco 7513,
Cisco 7513-MX, and Cisco 7576.
Note
In a Cisco 7513 or Cisco 7513-MX that has the high system availability (HSA) feature enabled and an
RSP2 configured as the system slave, online insertion and removal (OIR) of any interface processor in
either CyBus might cause the slave RSP2 to reboot with a bus error or a processor memory parity error.
