Cisco Cisco VN 2900 Network Adaptation Interface Installation Guide

Limitations of the single-mode and dual-mode access point HWICs include the following:

Only one access point HWIC is supported in the router at a time. Installation of two access point 
HWICs in the router is not supported.

The access point HWIC must be installed in an HWIC slot. To determine which slots on your 
platform support HWICs, see the 

.

The 4.9-GHz band is not supported.

Although the use of two antennas is not required, both antennas should be used to take advantage of 
diversity for the best RF performance.

The following are guidelines for wireless access devices:

Do not touch or move antenna(s) while the unit is transmitting or receiving.

Do not hold any component containing a radio so that the antenna is very close to or touching any 
exposed parts of the body, especially the face or eyes, while transmitting.

The use of wireless devices in hazardous locations is limited to the constraints posed by the local 
codes, the national codes, and the safety directors of such environments.

For regulatory information about the access point HWIC, see the 

Before working on a chassis or working near power supplies, unplug the power cord on AC units; 
disconnect the power at the circuit breaker on DC units. Statement 12
