Information About Configuring Power over Ethernet

When an access point that has been converted to lightweight mode (such as an AP1262) access point is powered by a power injector that is connected to a Cisco pre-Intelligent Power Management (pre-IPM) switch, you must configure Power over Ethernet (PoE), which is also known as inline power .

How to Configure Power over Ethernet

Configuring Power over Ethernet (CLI)

Procedure

  Command or Action Purpose
Step 1

ap name Cisco_AP power injector installed

Example:

Device# ap name AP02 power injector installed

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

Note 

Enter this command if your network contains any older Cisco 6-W switches that could be accidentally overloaded if connected directly to a 12-W access point. Make sure that the Cisco Discovery Protocol (CDP) is enabled before entering this command. Otherwise, this command will fail.

Step 2

ap name Cisco_AP power injector override

Example:

Device# ap name AP02 power injector override

Removes the safety checks and allows the access point to be connected to any switch port. 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.

Step 3

ap name Cisco_AP power injector switch-mac-address switch_mac_address

Example:

Device# ap name AP02 power injector
 switch-mac-address 10a.2d.5c.3d

Sets the MAC address of the switch port that has a power injector.

Note 

Enter this command if you know the MAC address of the connected switch port and do not want to automatically detect it using the installed option.

Step 4

show ap name Cisco_AP config general

Example:

Device# show ap name AP02 config general

Displays common information that includes the PoE settings for a specific access point.

Note 

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

Configuration Examples for Configuring Power over Ethernet

Displaying Power over Ethernet Information: Example

This example shows how to display common information that includes the PoE settings for a specific access point:

Device# show ap name AP01 config general

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)
