Power Injector Selection—This parameter enables you to protect your switch port from an
accidental overload if the power injector is inadvertently bypassed. It appears if you check the Power
Injector State check box above. Choose one of these options from the drop-down box to specify the
desired level of protection:

Installed—This option 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.

Note
Each time an access point is relocated, the MAC address of the new switch port will fail
to match the remembered MAC address, and the access point will remain 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.

option to cause the new MAC address to be remembered.
–
Override—This option allows the access point to operate in high-power mode without first
verifying a matching MAC address. It is acceptable to use this option if your network does not
contain any older Cisco 6-Watt switches that could be overloaded if connected directly to a
12-Watt 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-Watt switch, an overload will
occur.

Foreign—This option causes the Injector Switch MAC Address parameter to appear. The
Injector Switch MAC Address parameter allows the remembered MAC address to be modified
by hand. Choose this option if you know the MAC address of the connected switch port and do
not wish to automatically detect it using the Installed option.
