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.

1.

Controller module LEDs: The controller module LEDs should all flash green.

2.

Drive tray LEDs: The LEDs of all the drive trays (that contain hard drives) should be con-

stantly lit green to indicate that the drives have successfully spun up and are ready for 

I/Os.

3.

LCD panel LEDs: The blue LED on the LCD panel should come on indicating that power is 

being supplied to the system.

4.

Firmware and Bosch RAIDWatch: The overall status of the system may be checked using 

the terminal interface or the Bosch RAIDWatch GUI.

5.

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 during the initialization stage, indicating the 

RAID controller unit is attempting to access the hard drives.

When powering on the subsystem, the following messages should appear on the front panel 

LCD screen. Wait for the front panel LCD to show “READY” or “No Host LUN” before turning 

on the host computer. Refer to Figure 5.3 on how to read the screens.

The subsystem has been designed to run continuously. If a hot-replaceable component fails, 

the fault can be corrected online.
