4   Power Supply

4.1 Powering Up and Local Power Monitoring

To turn on power in a Quartet frame, remove the front panel and place the power switch in
the '1' position. The PWR indicator will light up. The following indicators provide information
on the power supply's status.

•

PWR

The PWR LED turns on to indicate the housing frame is powered.

•

FAIL

The FAIL LED turns on to indicate that at least one power supply voltage level has
failed. This may also occur after a thermal shutdown by the power supply. A thermal
shutdown occurs at a temperature of 70

°

C (158

°

F) setting all output voltage levels to 0.

The power supply will restart only when its temperature has dropped to at least 50

°

C

(122

°

F).

•

O/L

This LED lights up to indicate a current overload has been detected on one of the DC
power lines. This indicates a problem with either the power supply or one of the housing
frame's modules.
