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.)

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

•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:

Cisco 2821	1 to 2 may be installed	1 may be installed1	Slot 0 to slot 3
Cisco 2851	1 to 2 may be installed	1 may be installed1	Slot 0 to slot 3
Cisco 3825	1 to 4 may be installed	1 to 2 may be installed	Slot 0 to slot 3
Cisco 3845	1 to 4 may be installed	1 to 2 may be installed	Slot 0 to slot 3

1 Requires Cisco IOS Release 12.4(24)T or later.

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

Figure 1 HWIC-1FE Faceplate

Figure 2 HWIC-2FE Faceplate

Table 2 Fast Ethernet HWIC 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

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 Cisco Access Routers.)

---

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, 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.
