Chapter 4: Subsystem Connection and Operation

4-7

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.

4.3.4 Power 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.

Audible Alarm -

If any errors occur during the initialization process, the onboard

alarm will sound in a hastily repeated manner.

Drive tray LEDs should normally start flashing right after power-on, indicating the RAID

control unit is attempting to access the hard drives.

NOTE:

The subsystem has been designed to run continuously. Even if a component failure

occurs the fault can be corrected online.
