Powering the Access Point
The access point can be powered by one of these methods:
•
•
•
•
In all cases above, the AC branch circuit powering the access point must be limited to no more than 20A
Note
from the over-protection device supplied by the user. This branch power protection must meet all local
and national electrical codes.

Connecting a 1500 Series Power Injector

The power injector provides 56 VDC to the access point over the Ethernet cable and supports a total
end-to-end Ethernet cable length of 100 m (328 ft) from the switch to the access point.
The cable from the power injector to the access point and/or switch should be at least 10 ft (3.05 m) long.
Note
The PoE-Out port is disabled when the access point is powered by the power injector.
Note
When your access point is powered by an optional power injector, follow these steps to complete the
installation:
Step 1 Before applying PoE to the access point, ensure that the access point is grounded (see the
