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.

…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.
