After installing all the components in the subsystem, connecting the host channels to the 

host, and connecting the expansion cables to the expansion enclosures, the subsystem is 

ready to be powered on. 

BEFORE powering on the subsystem, please check the following:

•

Memory module: Memory module has been correctly installed on the controller board.

•

BBU modules: Ensure that the BBU modules have been installed correctly.

•

Hard drives: Hard drives have been correctly installed on the drive trays.

•

Drive trays: ALL the drive trays, whether or not they have a hard drive, have been installed 

into the subsystem.

•

Cable connections: The host ports on the subsystem have been correctly connected to 

host computer(s).

•

Power cables: The power cords have been connected to the PSU modules on the subsys-

tem and plugged into main power.

•

Ambient temperature: All the subsystem components have been acclimated to the sur-

rounding temperature.

When powering on the subsystem, please follow the steps below:

1.

Power on any expansion enclosures if applied

If you connect any expansion enclosures to the subsystem, power on those expansion 

enclosures before powering on the subsystem.

2.

Power on the subsystem

The subsystem should be powered on before the host computers. The power on proce-

dure for the subsystem is described in Section 5.4.3 Power On Procedure.

3.

Host computers

Host computers should be the last devices that are turned on. Please refer to the docu-

mentation that came with your host computers to see its own power on procedure.

1.

Plug in all power cords to the power connectors located at the rear of the subsystem. Use 

the power cables that came with the subsystem to connect the subsystem to the power 

outlet, separate power sources, or UPS devices.

2.

Turn on the power supply switches for both power supply units.

3.

The subsystem is now turned on and the self-test will start automatically.

4.

The “Power” LED on the front LCD panel will turn blue. 

Although the PSUs are redundant and a single PSU can provide sufficient power to the sys-

tem, it is advisable to turn both the power switches on. If only one PSU is operating and fails, 

the whole system will shut down.
