Remove and replace the peripheral power supply in a running system. Do not replace the PPS when the system is in the low power mode.
Verify that the system is running and is not in the low power mode.
If you replace the PPS in low power mode, the system will power on unexpectedly. Note that when the system is in low power mode, the front panel and board LEDs are all off, and the yellow power supply LEDs are on.
Verify that onboard peripheral devices are not in use, or data may be lost.
Note that while the PPS is removed:
There is no peripheral power, and onboard peripheral devices will not operate.
There is no precharge current. Do not attempt to replace hot-pluggable devices except for the PPS itself.
Use a Phillips #1 screwdriver to unlock the quarter-turn access slots (Figure 7-2) on the power supply.
Pull out the power supply.

Place the replacement PPS halfway into the slot, and:
Slide the PPS to the centerplane, then use the extraction levers to seat the PPS.
Simultaneously swing both levers inward to the locked position. Do not press on the front panel of the power supply to seat it; doing so will damage the connector pins.
DO NOT FORCE the power supply into a slot; this can damage the power supply and the centerplane.
The power supply should insert and seat smoothly. If it binds, remove it, and inspect the slot for any obstructions. Do not damage the springfingers at the bottom of the power supply.
Use a Phillips #1 screwdriver to turn quarter-turn access slots to the locked position (Figure 7-2).
Be sure the green LED is lit.
If the green LED is not lit, the power supply may not be seated properly. Check to see if it is seated properly by repeating Step 3 to Step 9. If the green LED is still not lit, see Chapter 10, Flow Diagrams for Troubleshooting for more information.
