The Dell PowerConnect W-AP175 is a resilient, environmentally hardened, outdoor rated, dual-radio, dual-band 
IEEE 802.11 a/b/g/n wireless access point. This outdoor access point is part of Dell’s comprehensive wireless 
network solution. The W-AP175 works only in conjunction with an Dell PowerConnect W-Series controller and 
each AP can be centrally managed, configured, and upgraded through the controller.

There are three versions of the W-AP175, which mainly differ in the way they receive power.

W-AP175P: PoE+ powered (802.3at)

W-AP175AC: AC powered (100-240 V AC)

W-AP175DC: DC powered (12-48 V DC)
