Cisco Cisco VN 2900 Network Adaptation Interface Installation Guide

To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, 
connect the Gigabit Ethernet high-speed WAN interface card (HWIC-1GE-SFP) only to intra-building 
or non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be 
grounded at both ends.

The Cisco Gigabit Ethernet high-speed WAN interface card itself is not hot-swappable. Removal or 
insertion of the Cisco Gigabit Ethernet high-speed WAN interface card requires powering down the 
router.

The Cisco Gigabit Ethernet high-speed WAN interface card supports the SFPs shown in 

.

Only Cisco-certified SFPs are supported on the Cisco Gigabit Ethernet high-speed WAN interface card.

When switching from one type of SFP to another, connection problems, including connection failure, 
may result. Use the show controller command at the Cisco IOS command-line interface (CLI) to 
determine whether you are using an SFP certified by Cisco.

Different SFPs have different cabling requirements; see the 

 for more information on SFP cabling.
