Cisco Aironet Series 702W Access Point Deployment Guide
AP-702W
Note
At this time there is no method of disabling the “ask” for additional power if high power is
present. There is a feature request to better handle this in the future, but if the goal is to have the
AP-702W not ask for additional power, then a work around would be to configure the powering
device to only allocate 15.4 W (802.3af) power on the port that the AP-702W is attached.
‘
Local power supply
AIR-PWR-C=
may be used. Do not use
AIR-PWR-B
.
Note
If PoE+ or 802.3at power source is present, the AP will negotiate higher power. If this is not
desired, a work around is to limit PoE on switch to 15.4 W until addressed in release 8.1.
Note
If the unit is powered by 802.3at (PoE+) then the device can deliver PoE out of port 4 at 7 W
output. If 802.3af (15.4 W) is desired out of Port 4, then the local power supply AIR-PWR-C
must be used.

This is the power required at the PSE, which is a switch or injector.

In the 7.6 version code, the draw is 30 W and in the 8.0 code, the draw is now reduced to 22.1 W.
