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.
