WRU Deploying

If power is removed from a WRU in the deploying state, the WRU stays in the deploying state

and restarts the deploying process when power is restored.

After removing both batteries from a deploying WRU, and then replacing BAT A, BAT B, or

both, when the first battery is connected, the WRU goes through the power on LED

sequence. If both batteries are connected, the battery fuse test is executed. If only one

battery is connected, the battery fuse test is skipped. The remainder of the self-tests are

then executed.

The following table shows the LED power-on sequence for an deploying WRU:

No neighbor

detected

RAD Solid

If this is the first WRU deployed, this is the

expected condition.
