Astaro Security Gateway 625
Operating Instructions
8. Redundant power supply
The Astaro Security Gateway 625 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 defect 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 defective of 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 of 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 in particular to remove the defective power unit from the power
supply system, otherwise the complete 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
not available for the security appliance if a defect has been caused by the
use of power units which are not suited for the system.
Exchanging a power supply unit
1. Identify the defective power supply unit.
Locate the defective power supply unit by examining the individual LEDs of
each unit—no LED light indicates a failure of the unit.
2. On the right side, open the interlock of the power supply unit.
3. Use the special bracket to pull the power supply unit out of the
chassis.
4. Now, insert the new power supply unit into the chassis.
5. Lock the new power supply unit.
6. Plug the power cable back into the connector of the new power
supply unit and check the following LED displays:
> LED of the new power supply unit lights green.
> LED indicating the total system power status lights green.
As soon as the new power supply unit is detected and functional, the
beeping sound will stop.
