Configuring Power over Ethernet

Note

Unselect the Pre-standard 802.3af Switches check box if power is being provided by a power injector. This

is the default value.

Step 5

Select the Power Injector State check box.

Select this check box if the attached switch does not support IPM and a power injector is being used. If the attached

switch supports IPM, you do not need to select this check box.

The Power Injector Selection drop-down list is displayed that contains parameters that enable you to protect your switch

port from an accidental overload if the power injector is inadvertently bypassed.

Step 6

From the Power Injector Selection drop-down list, choose an option to specify the desired level of protection.

You can choose any one of the following three options:

• Installed—Examines and remembers the MAC address of the currently connected switch port and assumes that a

power injector is connected. Choose this option if your network contains older Cisco 6-Watt switches and you want

to avoid possible overloads by forcing a double-check of any relocated access points.

If you want to configure the switch MAC address, enter the MAC address in the Injector Switch MAC Address

text box. If you want the access point to find the switch MAC address, leave the Injector Switch MAC Address

text box blank.

Note

Each time that an access point is relocated, the MAC address of the new switch port fails to match the

remembered MAC address, and the access point remains in low-power mode. You must then physically

verify the existence of a power injector and reselect this option to cause the new MAC address to be

remembered.

• Override—Allows the access point to operate in high-power mode without first verifying a matching MAC address.

You can use this option 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 advantage of this option is that if you relocate the access point,

it continues to operate in high-power mode without any further configuration. The disadvantage of this option is

that if the access point is connected directly to a 6-W switch, an overload occurs.

Step 7

Click Apply.

Step 8

Click Save Configuration.

What to Do Next

Manually reset the access point in order for the change to take effect.
