Installing the Access Point
Powering the Access Point
The access point can be powered by one of these methods:
•
•
•
•
Note
In all cases above, the AC branch circuit powering the access point must be limited to no more than 20A
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 (AIR-PWRINJ1500-2=) 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 PoE-Out port is disabled when the access point is powered by the power injector.
Note
When not using the AC input connector to power the 1552E or 1552EU (for example when powering
Note
using the Cisco power injector), it is important to cover the AC power entry connector. The correct cap
is Remke part number 75-0086 (http://www.remke.com/).
When your access point is powered by an optional power injector, follow these steps to complete the
installation:
Before applying PoE to the access point, ensure that the access point is grounded (see the

The 1550 power injector can only be used in an indoor environment, therefore, the cable from
the injector must travel from the protected location to the outside mounted access point.
