Note: If you are connecting the PC directly to the unit, you must use a crossover Ethernet cable between
the network interface card in the PC and the RJ45 “Data In” port on the power injector.
4) POWERING ON THE UNIT
Once you have connected the power injector to the Ethernet cabling and plugged the power injector cord into an
AC outlet, the unit is powered on. There is no ON/OFF switch on the unit. To remove power, unplug the AC cord
from the AC outlet or disconnect the 8-pin DIN connector from the “Data and Power Out” port on the power
injector.
Note: Proxim recommends the use of a lightning arrestor at the building ingress point. You can purchase the
Proxim Lightning Protector MP.11/QB.11 (70251); see the documentation that comes with the unit for
more information and installation instructions.
5) VIEW LEDs
When the unit is powered on, it performs startup diagnostics. When startup is complete, the LEDs show the unit’s
operational state. The LEDs are present at the unit’s Ethernet connector; unscrew the watertight cap if necessary
to view the LEDs.
Note: Make sure the domed sealing nut of the Liquid-Tite connector is loose before unscrewing the cap or the
Ethernet cable may be twisted and damaged.
During bootup, all LEDs are blinking. Blinking can continue for up to four minutes (when DFS is enabled, for
example); however, if the LEDs are still blinking for over four minutes, you should check your installation and
proper operation of the Ethernet and wireless links to other units. If they are correct, contact Technical Support;
there could be a problem with your hardware.
Note: When powering the unit in below freezing temperatures, the unit must self-heat before booting. This is
indicated by a solid red LED. This state can take up to 30 minutes, depending upon the ambient
temperature.
