1-10 Cisco 7010 Hardware Installation and Maintenance
Physical Description
Figure 1-7 Router System Architecture
The backplane slots are keyed so that the processor modules can be installed only in the slots
designated for them. Keys on the backplane fit into two key guides on each module. (See Figure 1-8.)
Although the RP, SP, and SSP each use unique keys, all three interface processor slots use the same
key, so you can install an interface processor in any interface processor slot.
Caution When installing an RP, SP, SSP, or interface processor, ensure that you are installing it in
the appropriate slot to avoid damaging the key guides or the backplane.
