1- and 2-Port Fast Ethernet High-Speed WAN Interface Cards
Fast Ethernet HWICs Port Numbering
Port numbers identify the interfaces on the modules and interface cards installed in the router. Modules
and interface cards are identified by three digits: slot number/subslot number/port number.
For example, HWIC port 0 in HWIC subslot 1 of router slot 0 is represented as:
Fast Ethernet HWICs LEDs
The Fast Ethernet HWICs use three LEDs per port to indicate full- or half-duplex operation, collisions,
speed, transmit/receive activity, and link status.
