Powering the Access Point
Powering the Access Point
The access point can be powered by one of these methods:
• PoE—56 VDC; for 1552E and 1552EU access points
–
Connecting a 1500 Series Power Injector, page 2-45
• AC power
–
110 to 240 VAC for a 1552I access point—Connecting Streetlight AC Power, page 2-51
–
110 to 480 VAC for 1552E and 1552EU access points—Connecting Streetlight AC Power,
page 2-51
–
120 VAC—Connecting an AC Power Cable to the Access Point, page 2-54
• External 12 VDC
–
Connecting a DC Power Cable to the Access Point, page 2-55
• POC—40 to 90 VAC (Quasi-AC); only for a 1552C and 1552CU access points
–

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.
Note 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
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:
Step 1 Before applying PoE to the access point, ensure that the access point is grounded (see the “Grounding
the Access Point” section on page 2-41.
Step 2 Review Figure 2-2 to identify the components needed for the installation.
Note 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.
