Power Cable Connections
The base unit is shipped in “Auto Power On” mode, so the base unit will turn on when the power cables are
plugged into the unit and an outlet. Therefore, the following steps should be followed before connecting any
power cables to the array:
•
Ensure that all disk drives are properly seated.
•
Ensure that all Ethernet and Fibre Channel cables have been properly connected.
•
Ensure that any SAS cable connections to additional disk enclosures are properly connected.
•
Plug in the power cables for any additional disk enclosures attached to the base unit before connecting
the base unit power cables.
To plug an AC power cable into a base unit or disk enclosure:
1. Spread the AC cable clamp.
2. Connect the power cable to the unit.
3. Loosely lock the clamp around the power cord, but do not tighten.
4. Move the clamp in the direction indicated in Figure 10 below until the clamp is fixed securely to the
base of the AC cable plug as shown, and then tighten.

Power-On/Power-Off Procedures
The array power buttons are located on each controller module at the back of the base unit, as shown in Figure
11 below.

Power-On Procedure When Auto Power On Mode Is Not Enabled
If the array has been shut down using the power button or if Auto Power On mode is not enabled, the array can
be turned on by depressing the power button and holding it in for approximately one second. If there are two
controllers on the base unit, only one power button needs to be depressed to turn an array on or off.
When the array is first powered on, it will perform a self-test as indicated by a flashing Service LED. After the
array has successfully finished the self-test process, the Power LED should remain lit and the Service LED
should turn off. Application servers can be connected to the array after the self-test is completed.
