CAUTION!
Although the PSUs are redundant and the subsystem can withstand a
single PSU failure, it is advisable to replace a failed PSU immediately.
The subsystem will be held in an idle state if two PSUs have already failed
in the subsystem.
Step 4. Power on the host computers.
The host computers are the last devices that are turned on.
Please refer to the documentation that came with your host
computers to see their own power on procedures.
4.5.3 Power On Status Check
Once the subsystem has been powered on, the status of the entire subsystem
should be checked to ensure that all components are receiving power and
functioning without complications or malfunctions.

active LEDs should all flash green after a successful initialization.
Drive tray LEDs – The blue LED for all the drive trays (that contain
hard drives) should light up, showing that there is power.
LCD panel LEDs – The blue LED on the LCD panel should be lit,
indicating that power is supplied to the system.
