Dell PowerVault 715N (Rackmount NAS Appliance) - Manual (Page 6)

Each hard drive has two LEDs. The LEDs are most visible when the bezel is attached to the front of the system. The LEDs
provide the following information for each hard drive:
When the LED on the left side is green, the hard drive is installed in the drive bay and working. When this LED is
amber, the hard drive is installed in the bay, but it is not working properly.
When the LED on the right side flashes amber, the hard drive is active.

System Beep Codes
When an error that cannot be reported through a console redirection screen occurs during a boot routine, the system
might emit a series of beeps that identify the problem. For example, five beeps indicate a problem with the processor.
This information is valuable to the Dell technical support representative if you must call for technical assistance.
When a beep code is emitted, record it, and then look it up in Table 2-2 . If you are unable to resolve the problem by
looking up the meaning of the beep code, use the System Diagnostics to identify a more serious cause. If you are still
unable to resolve the problem, see " Getting Help ," for information about obtaining technical assistance.
