Connecting 1- and 2-Port Fast Ethernet
High-Speed WAN Interface Cards to the Network

Revised: 04/20/2009, OL-12851-01

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, page 1

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
guide located at:

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:
