Chapter 7 Troubleshooting
DAS-208SA Disk Array employs a sophisticated combination of audio and
visual signals to warn or inform you of conditions that may require user‘s
attention. In this chapter, we will describe the diagnostic facilities that are
available as well as solutions to common problems.
This chapter will cover the following topics:
LEDs During Normal Operation
Alarm
Signals
7.1 LEDs During Normal Operation
During normal operation green POWER lights will be lit up, indicating that
power is being applied to the drives and that the drives are operational. Yellow
ACCESS LEDs will go off and on with each drive read or write operation.
Power supplies have green LEDs that stay on all the time if the power supply is
functioning properly (the LED will become red if one of the power supplies
fails). Fan failed red LEDs for the four cooling fans at the rear will light if the fan
fails.
7.2 Alarm Signals
Whenever there is a failed hard disk, fan, power supply or overheating
condition, the audio alarm will be triggered. Red LEDs will light up indicating
the part that has failed. The LCD panel will also display a warning message. To
turn off the alarm signal from the controller, enter the configuration mode (‘6
Raid Func’
Æ
’63 Beeper’) of the controller to disable the beeper.
