Powering Down the System (Optional)
Checking the CPU LEDs and Powering Down
Before powering down, you must check the CCPU blade LEDs.
1. Carefully check the CCPU LEDs (Figure 2: Checking the CCPU LEDs).
1a. Make sure that LED1 (the Run LED) is the only LED flashing on the CPU.
(
LED1 flashes green 1/2 second on and 1/2 second off.)
1b. If any other LEDs on the CPU are flashing, wait until they stop.
1c. If you turn off the system while LEDs other than LED1 are flashing, system data could
become corrupted as the system powers down.
2. Turn the power switch to OFF (0).
3. Wait about 5 seconds for the system to shut down.
3a. The blue LED adjacent to the power switch will go out.

Skip this step if you have chosen to insert the UX Mail blade “hot” (with power applied).
• Go right to INSTALLING THE UX MAIL BLADE (PAGE 3) instead.
