Power Injector module (AIR−PWRINJ or AIR−PWRINJ3)
The Power Injector module is a simple device with two ports:
One port connected to the bridge or AP♦
The other port connected to the wired part of the network, such as a noninline−capable switch
or a hub
♦
The module is connected to an AC adapter that provides the connection to the power cord.
Caution: You can use the Cisco Power Injector with these devices only:
BR350 (AIR−PWRINJ)♦
AP350 (AIR−PWRINJ)♦
AP1100 (AIR−PWRINJ3)♦
AP1200 (AIR−PWRINJ3)♦
If you attach any other Ethernet device to the power end of the power injector, damage to the Ethernet
device occurs. These are examples of such Ethernet devices to avoid:
BR340♦
Workgroup bridge (WGB)♦
Network interface card (NIC)♦
Hub♦

Note: The maximum distance that is supported for inline power is 100 meters (m). This distance is the same
for every Ethernet connection over Category 5 cable.
