Monitoring power supply status
To determine power supply status:
1. Observe the LED indicator on the power supply (see Figure 31 (page 62)). The LED patterns
may temporarily change during POST and other diagnostic tests; for information about how
to interpret the LED patterns, see Table 12 (page 62).
2. Enter the psShow command to verify power supply status.
The power supply status displays OK, Absent, or Faulty. If a power supply is absent or faulty,
contact HP to order replacement power supply.
