Chapter 4: Subsystem Connection and Operation

The servers or iSCSI initiators should be the last devices that are turned on. Please refer to the documentation that came with your application servers to see their own power on procedures.

4.3.3Power On Enclosure

To power on the subsystem, turn on the two power switches located on the rear panel of the subsystem. (See Figure 4-3) Each switch controls a single PSU, therefore make sure that both switches are turned on. There is no limitation on which PSU should be powered on first.

Figure 4-3: Power Switches

CAUTION!

Although the PSUs are redundant and a single PSU can provide sufficient power to the subsystem, it is advisable to turn both of the power switches on. If only one PSU is operating and fails, system operation will be terminated.

4.3.4Power On Status Check

Once the subsystem has been powered on, the status of the entire subsystem should be checked to ensure that everything is running smoothly and that there are no complications or malfunctions.

Controller Module LEDs – The controller ready LED should flash green.

Drive Tray LEDs – The drive status LEDs (that contain hard drives) should all lights blue.

Firmware and RAIDWatch – The overall status of the system may be checked using the embedded firmware utility or the RAIDWatch GUI screen.
