Astaro Security Gateway 525
Operating Instructions
Important note:
Except for short periods of time (e.g., swapping hard disks),
do not operate the server with an empty hard disk drive.
As soon as the security appliance detects the new hard disk, the existing
hard disk is mirrored to the new hard disk. This process may take 30
minutes or more. The current status of the RAID system is displayed on
the dashboard in the RAID status section. Prior to and after termination of
the saving process, a corresponding notification email will be sent to the
administrator.
8. Redundant power supply
The Astaro Security Gateway 525 is equipped with a redundant power
supply. The power supply system consists of two separate power supply
units. This power supply system increases the availability of the security
appliance, since a defective power supply unit can be exchanged easily and
quickly during operation.
When the system is running error-free, the power fail LED on the front
doesn't light and the LED on the back of the appliance shows green. In the
event of a hardware defect in one of the power supply units these LEDs will
turn red and you will hear a continuous beeping sound. The warning sound
can be reset by pressing the red buzzer reset switch on the system chassis.
This buzzer reset switch is on the back of the appliance right beside the
power supply system.
Important note:
If you need to change a power unit because of a defect,
remember to remove the defective power unit from the power supply
system, otherwise the whole security appliance will fail.
Protect yourself from potential burns by wearing protective gloves when
exchanging a power supply unit.
Only use power units which you purchased directly from Sophos or from a
Sophos distribution partner. Please remember that any warranty claims are
voided for the security appliance if a defect has been caused by the use of
power units which are not suited for the system.
