Install the QM561 power supply units as follows:
1. Unpack the QM561 power supply units and remove the blank from the
interconnect enclosure, if fitted.
2. If only fitting one QM561 power supply unit, insert it into slot PSU A and fit
slot PSU B with a QM566 power supply blank. If fitting two QM561 PSUs,
insert them in slots PSU A and PSU B.
3. When a QM561 power supply unit is fully inserted, the locking latch secures
the QM561 in place.
The QM561 power supply unit has four LEDs, as shown in Table 7-1 that indicate
the status of the module.
Table 7-1: Table 2-3 Power Supply LEDs
Label
Color Status when Lit
AC OK Green QM561 ON and mains OK
Red Mains fault
Fault Red QM561 fault
Over Temp Red QM561 over temperature alarm is active
DC OK Green DC output OK
Amber DC output fault
To verify that a QM561 power supply unit is operational, ensure that both the AC
OK and the DC OK LEDs are lit up green, while both the Fault and the Over
Temp are unlit.
