To the right of the power supply bays, the processor slots house the processor modules. In the Cisco 7000, the RP is always located in the far right slot (the RP slot), and the SP (or SSP) is always located in the adjacent slot. The remaining five interface processor slots, numbered 0–4 from left to right, support any combination of network interface types: serial, FDDI, Ethernet, and Token Ring, and so forth.

In the Cisco 7507, the RSP2 is always located in slot 2 or 3. The remaining six interface processor slots, numbered 0 and 1 and 4 through 6, from left to right, support any combination of network interface type.

The processor modules slide into the slots and connect directly to the backplane. The backplane slots are keyed to guides on each type of board. (See Figure 4 for the Cisco 7000 and Figure 5 for the Cisco 7507.) The keys ensure that the processor modules can be installed only in their designated slots.
