NOTICE!

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

5.3.4Power 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, Host Ports Active, and Device Ports Active LEDs should all flash green.

• Drive Tray LEDs – The green LED for all the drive trays (that contain hard drives) should light up, showing that there is power.

• 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 units are attempting to access the hard drives.

NOTICE!

The subsystem has been designed to run continuously. Even if a component failure occurs the fault can be corrected online.

5.4Power Off Procedure

To power down the RAID subsystem, please follow these steps:

NOTICE!

i

When powering down the RAID subsystem, please ensure that no time-consuming processes, like a “Logical Drive Parity Regeneration” or a “Media Scan,” are taking place.

1.Stop I/O access to the system.

Stop all I/O accesses to the RAID subsystem. Please refer to the related documentation of your applications.

2.Flush the cache.

Locate the Cache_Dirty LED on the back of controller module to check if there is still cached data in memory. Use the Shutdown Controller function to flush all cached data. This prepares the RAID subsystem to be safely powered down.

3.Turn off the power.

Turn off the power switches at the top of the rear panel of the RAID subsystem. Once the RAID subsystem has been powered down, other devices connected to the subsystem may be powered down.
