Cisco EHWIC-1GE-SFP-CU is an Enhanced High-Speed WAN Interface Card (EHWIC) used in Cisco ISR 1900, 2900, and 3900 series routers.
It provides a flexible Gigabit Ethernet WAN interface, combining:
- 1 × RJ-45 10/100/1000 Mbps copper port
- 1 × SFP slot for fiber or copper transceivers
Only one interface (SFP or RJ-45) can be active at a time, making it a dual-purpose WAN uplink module for enterprise routers.
Key Features
- Dual-mode interface: RJ-45 Gigabit + SFP slot
- Supports 10/100/1000 Mbps Ethernet
- Compatible with Cisco ISR:
- 1921 / 1941
