In the Catalyst series switches, we'll look specifically at the 5513 and 5509 chasses and the dependencies between the line cards and the different buses located on the backplane because this backplane architecture varies, depending on slot position. All other switch platforms have constant bus speeds across all slot positions, either 1.2 Gbps (5x00 series), 24 Gbps (4000 series), or 32 Gbps (6000 series).
The 5500 has three buses (classified as A, B, and C) of 1.2 Gbps each, and 13 slots. Figure 10-1 shows the bus and slot designations for a 5513 switch.
The slots are designated as follows:
Slot 1 is reserved for the supervisor engine, which provides ...
