Connecting 1- and 2-Port Fast Ethernet High-Speed WAN Interface Cards to the Network
Connecting Fast Ethernet HWICs to a Network
Connecting Fast Ethernet HWICs to a Network
To connect a Fast Ethernet HWIC to the network, do the following procedure:
Step 1
Confirm that the router is powered down.
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the HWIC-1FE and HWIC-2FE interface cards only to intra-building or unexposed wiring or
cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. The
intra-building port(s) of the equipment or subassembly must not be metallically connected to
interfaces that connect to the OSP or its wiring. These interfaces are designed for use as
intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and
require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient
protection in order to connect these interfaces metallically to OSP wiring.
Step 2
Insert the Fast Ethernet HWIC into an HWIC slot on the router. (See Installing Cisco Interface Cards in
Note
Insert Fast Ethernet HWICs into HWIC slots only. They do not fit into WIC/VIC slots.
Using the appropriate cables, connect the HWIC to your system.
Step 3
Caution
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the 1-port HWIC (HWIC-1FE) and 2-port HWIC (HWIC-2FE) only to intrabuilding or
nonexposed wiring or cabling.

For 10BASE-T operation, Category 3, 4, or 5 UTP cable may be used, for distances of up to
328 feet (100 meters).
For 100BASE-TX operation, Category 5 UTP cable is required, for distances of up to
328 feet (100 meters).
The HWICs support Auto-MDIX, so either straight-through or crossover cable can be used.
Step 4
Power up the router.
