This guide describes how to connect Cisco 1- and 2-Port Fast Ethernet high-speed WAN interface cards
(HWICs) to your network. It contains the following sections:

Cisco 1- and 2-Port Fast Ethernet HWICs
The Cisco Fast Ethernet HWICs are single-wide interface cards, available as a 1-port HWIC
(HWIC-1FE) and as a 2-port HWIC (HWIC-2FE), that provide Cisco modular and integrated services
routers with additional line-rate Layer 3 routed ports. (See the “Fast Ethernet HWICs Supported
Platforms” section on page 2.)
Fast Ethernet HWICs Standards
The Fast Ethernet HWICs are designed in accordance with IEEE 802.3 10BASE-T Ethernet and IEEE
802.3u 100BASE-TX Fast Ethernet standards.
The following IEEE standards are also supported:
• 802.1p
• 802.1u
• 802.1x
Fast Ethernet HWICs Restrictions
The following features are not supported on the Fast Ethernet HWICs:
• Cisco Interswitch Link (ISL) tagging

Cisco 1- and 2-Port Fast Ethernet HWICs
• Connectivity fault management (CFM)
• Flow control
• Online insertion and removal (OIR)
Fast Ethernet HWICs Supported Platforms
Install the Fast Ethernet HWICs in the following Cisco routers:
• Cisco 1841 integrated services router
• Cisco 2800 series integrated services routers
• Cisco 3800 series integrated services routers
Note Insert Fast Ethernet HWICs into HWIC slots only. They do not fit into WIC/VIC slots.
Table 1 shows the maxmum number of each type of HWIC that may be installed, the slot locations, and
slot numbering for each platform.
For information about HWIC slot locations on each router, see the “Interface Card Slot Locations and
Numbering on Cisco Access Routers” section of the Cisco Interface Cards for Cisco Access Routers

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. Figure 1 and Figure 2 show the HWIC-1FE and
HWIC-2FE faceplates, and Table 2 describes the functions of the LEDs.

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
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.
Step 3 Using the appropriate cables, connect the HWIC to your system.
Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
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.
Cisco Access Routers.)
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.
