  • 1.  AP-655 Power

    Posted 27 days ago

    I have an AP-655 connected to a cisco switch configured to provide 53W on a port.  The AP is only connected to E0 but is running in power restricted mode.  According to the switch the AP is only requesting 25.5W.  Is there a guide for configuring the AP-655 to using only one port for PoE without power restrictions?

    Is the switch configured to support 802.3bt?  Default can be to run in proprietary UPoE mode.

    This turned out to be the issue, Cisco's proprietary PoE was causing some problems with LLDP negotiating class 4, 25.5W, instead of class 6.  Changing settings on the cisco switch, in this case a 3850, allowed for 60W to be delivered.  They are still showing up as class 4 devices on the switch, though they are getting BT power.  Consolidated Platform Configuration Guide, Cisco IOS XE 3.7E and Later (Catalyst 3850 Switches) - Configuring PoE [Cisco Catalyst 3850 Series Switches] - Cisco

    The commands used to enable 60W on the port were:

    power inline static
    power inline four-pair forced

    Still showing as Class 4 because you didn't tell the switch to operate in standards mode, but that might not even be possible with that particular switch.

    May I know any L2-protocol are you running on switch end for transmitting TLV elements?

    Sounds like the switch does not know which class of power to use. Make sure lldp is turned on.
