Introduction
Power Supply Front Panel Layout
1.4 Power Supply Unit Front Panel Layout
The power supply individual front panels contain the input ON/OFF
circuit breakers and the FAULT, MASTER / STANDALONE and SLAVE
indicators. Refer to Figure 1-2 and Table 1-3. for a description of front
panel controls and indicators.

2 SLAVE indicator
Lights when set as SLAVE Model 4Q06125PS in the
4Q12125PS configuration.
3 MASTER indicator
Lights when configured as MASTER Model 4Q06125PS
in the 4Q12125PS configuration
4 FAULT indicator
Lights red when a fault is detected. The following failure
or fault conditions can cause the FAULT indicator to light:
overtemperature, instant internal overcurrent, output
overvoltage/overcurrent, local 15V failure, input under/
overvoltage, input overcurrent, internal output under/
overvoltage, internal output overcurrent, overtempera-
ture, fan failure.
When the FAULT indicator lights, an audible beep
sounds a warning for approximately two seconds and the
output is crowbarred by an internal contactor. The fault is
latched. After the cause of the fault is removed, the unit
can be restarted by cycling the POWER circuit breaker to
OFF, then ON, or by applying a START_EXT pulse at
