Use these commands to configure and See PoE settings using the controller CLI:

• If your network contains any older Cisco 6-W switches that could be accidentally overloaded if connected directly to a 12-W access point, enter this command:

  config ap power injector enable {Cisco_AP | all} installed

  The access point remembers that a power injector is connected to this particular switch port. If you relocate the access point, you must reissue this command after the presence of a new power injector is verified.

  Note	Ensure CDP is enabled before entering this command. Otherwise, this command will fail.

• Remove the safety checks and allow the access point to be connected to any switch port by entering this command:

  config ap power injector enable {Cisco_AP | all} override

  You can use this command if your network does not contain any older Cisco 6-W switches that could be overloaded if connected directly to a 12-W access point. The access point assumes that a power injector is always connected. If you relocate the access point, it continues to assume that a power injector is present.

• If you know the MAC address of the connected switch port and do not want to automatically detect it using the installed option, enter this command:

  config ap power injector enable {Cisco_AP | all} switch_port_mac_address

• If you have a dual-radio 1250 series access point and want to disable one of its radios in order to enable the other radio to receive full power, enter this command:

  config {802.11a | 802.11b} disable Cisco_AP

  Note	You must manually reset the access point in order for the change to take effect.

• See the PoE settings for a specific access point by entering this command:

  show ap config general Cisco_AP

  Information similar to the following appears:

  
  Cisco AP Identifier.............................. 1
  Cisco AP Name.................................... AP1
  ...
  PoE Pre-Standard Switch.......................... Enabled
  PoE Power Injector MAC Addr...................... Disabled
  Power Type/Mode.................................. PoE/Low Power (degraded mode)
  ...

  

  The Power Type/Mode text box shows “degraded mode” if the access point is not operating at full power.

• See the controller’s trap log by entering this command:

  show traplog

  If the access point is not operating at full power, the trap contains “PoE Status: degraded operation.”

• You can power an access point by a Cisco prestandard 15-W switch with Power over Ethernet (PoE) by entering this command:

  config ap power pre-standard {enable | disable} {all | Cisco_AP}

  A Cisco prestandard 15-W switch does not support intelligent power management (IPM) but does have sufficient power for a standard access point. The following Cisco prestandard 15-W switches are available:

  • WS-C3550, WS-C3560, WS-C3750

  • C1880

  • 2600, 2610, 2611, 2621, 2650, 2651

  • 2610XM, 2611XM, 2621XM, 2650XM, 2651XM, 2691

  • 2811, 2821, 2851

  • 3631-telco, 3620, 3640, 3660

  • 3725, 3745

  • 3825, 3845

  The enable version of this command is required for full functionality when the access point is powered by a Cisco prestandard 15-W switch. It is safe to use if the access point is powered by either an IPM switch or a power injector or if the access point is not using one of the 15-W switches listed above.

  You might need this command if your radio operational status is "Down" when you expect it to be "Up." Enter the show msglog command to look for this error message, which indicates a PoE problem:
