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:
interface FastEthernet 0/1/0
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. Figure 113 and Figure 114 show the HWIC-1FE and
HWIC-2FE faceplates, and Table 33 describes the functions of the LEDs.

LED Meaning States
FDX/COL Duplex/Collision On = Full-duplex
Off = Half-duplex
Blinking = Collision activity
100 Speed On = 100 Mbps
Off = 10 Mbps
LNK/ACT Link Status On = Link pulses detected
Off = No link pulses detected
Blinking = Transmit or receive activity
