Cisco HWIC-1FE Full Official Product Description
1. Part Number & Naming Definition
Official Full Name
Cisco 1-Port Fast Ethernet High-Speed WAN Interface Card
Spare SKU:HWIC-1FE=
Naming Breakdown
-
HWIC: High-Speed WAN Interface Card
-
1FE: Single 10/100BASE-TX Fast Ethernet routed port
Core Product Positioning
The Cisco HWIC-1FE is a single-wide pluggable Fast Ethernet interface card built for Cisco ISR modular integrated service routers. It delivers an additional independent Layer 3 routed Fast Ethernet port, extending network connectivity for WAN access, local aggregation, inter-router links and backup network paths. Equipped with dedicated hardware forwarding and a unique MAC address, it operates identically to the onboard router LAN interfaces, supporting rich enterprise routing, QoS and security functions for branch office multi-homing and network expansion.
