SCA / SATA drive panel — This panel houses the RAID5 hard drives. One hard drive
A
is referred to as a hot spare drive, which is a drive that is inactive until an active drive
fails. When an active drive fails, the hot spare drive rebuilds the data of the failed drive
so that the system can recover.
Power button — This is the main power button, which is used to apply or turn off the
B
main power. When the main power is turned off, standby power is actively supplied to
the recorder.

If the recorder requires service, disconnect the power supply from
the recorder before proceeding.

Si l'entretient de l'enregistreur doit être fait, débranchez la source
d'alimentation de celui-ci avant de procéder.

Status LED Icons
Power LED — This LED lights when the recorder is receiving power.
•
Drive Activity LED — This LED indicates drive activity when flashing or flickering.
•
NOTE: This light may not respond and an audible alarm may go off if a
hard drive has failed. Check to see if a hard drive has failed and replace if
necessary.
Network Activity LED (1) — This LED flashes to indicate activity on the first
•
network.
Network Activity LED (2) — This LED flashes to indicate activity on the second
•
network.
Overheat and Fan Failure LED — When this LED is flashing, it indicates that a
•
fan has failed inside the recorder. When the LED is continuously lit, it indicates that
the recorder has achieved a condition which may cause it to overheat. This LED will
remain flashing or on for as long as these conditions exist.
NOTE: If the LED is continuously lit, the condition may be caused by cables
obstructing the airflow of the recorder or the ambient room temperature.
Check the routing of the cables and make sure all fans are operating normally.
If necessary, move the recorder to a cooler location or adjust the room
temperature.
Power Supply/Fan Failure LED — When this LED is lit, it indicates a power
•
supply fan has failed. The power supply module has a redundant backup fan that
will increase its speed to compensate, but the power module should be replaced as
soon as possible. The recorder may sound louder than usual during operation until
the power supply is replaced.
