unit. A QM566 power supply blank must be fitted to slot B if only one QM561 power supply unit is fitted. Figure 7-7: Inserting or Removing a Power Supply QUaDrics QsNet" PSU A PSU B PSU A Latch HPTC-0033 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.

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.
