About Power Over Ethernet
Airespace equipment supports 802.3af-compliant Power over Ethernet (PoE),
which can reduce the cost of discrete power supplies, additional wiring,
conduits, outlets, and installer time. PoE also frees installers from having to
mount an Airespace Access Point or other powered equipment near AC
outlets, providing greater flexibility in positioning APs for maximum coverage.
When you are using PoE, the installer runs a single CAT-5 cable from each
Airespace AP to the PoE-equipped Airespace Wireless Switch or other network
element, or to a PoE power hub. When the PoE equipment determines that
the Airespace AP is PoE-enabled, it sends 48 VDC over the unused pairs in
the Ethernet cable to power the Airespace AP.
Note: Airespace APs can receive power from the Airespace Switch, or
any other network device conforming to the IEEE 802.3af standard.
Note: Each Airespace AP can also receive power from an Airespace AP
External Power Converter.
The Airespace Switch can be ordered with or without PoE, as required. It can
be ordered with internal PoE or an external PoE hub. Contact Airespace for
recommended external PoE hubs.
