Applying AC Power (# 7626 AC-Power units)

1. To view the wireless repeater board, open the shelter enclosing the wireless repeater.

2. Thread the power adapter plug through the square black grommet into the repeater

shelter.

Every Davis shelter has two of these grommets at the bottom of the shelter to provide

weather-resistant entrances for cables. If it is too hard to thread the power adapter

cable through the grommet in its current position, remove the grommet, thread the

power adapter plug through it, and replace the grommet in the shelter.

3. Insert the AC adapter plug into the

repeater power jack at the top of the

board above the battery socket.

Make sure the AC adapter is

plugged into the outlet.

If the battery has not already been

installed, the wireless repeater

begins powering the board. The

repeater immediately performs the

Power-On Self Test (POST) using

the two LEDs located at the bottom

of the board. The STAT LED blinks

red, yellow and then green, fol-

lowed by the TX LED blinking

green once, indicating that the repeater is powered up and has passed POST.

4. Once the POST light sequence displays, the repeater is ready to communicate. If the

repeater has not displayed the POST light pattern, unplug the AC adapter from the

repeater, wait for about a minute and plug it back in. If the repeater has still not per-

formed POST and displayed the light pattern, see “Maintenance and Troubleshooting”

on page 36 for more information.
