Modules in the switch are connected to each other via the backplane. The switch
processor (SP) controls the switch and interacts with multiple I/O processor (IOP)
modules. The IOPs can accommodate numerous interface specifications, speeds, and
protocols as they process signal traffic.
The IOPs connect to the network via their I/O adapter (IOA) modules. The SPs
connect to a similar network interface module called a switch processor adapter
(SPA). The IOAs and SPA contain the connections for network cables and provide a
hardware bridge between the physical network and the IOPs.
