Power Subsystem
007-4276-001 35
Warning: Hazardous voltage, current, and energy levels are present inside the
power subsystem. There are no user-serviceable parts inside it; servicing should be
done by technically qualified personnel.
Caution: Once you remove a power supply, make sure you replace it within two
minutes. If not possible in this time frame, re-insert the original unit. When a replacement
unit is available, repeat the replacement procedure. Vacant spaces alter airflow patterns
in the server system and may cause environmental conditions to exceed the
environmental limits of the server.
Removing a Power Supply Module
To remove a power supply module, follow these steps:
1. Remove the front bezel by gently pulling on the edge of the front bezel. The ball
studs of the bezel release. Check the LED for each power supply module to
determine which power supply module needs to be replaced.
2. Loosen the power supply module retaining screw. See Figure 2-5 on page 34 for the
location of the screw.
3. Press down on the power supply module tab. Gently pull the power supply module
handle towards you and remove the power supply module from the power
subsystem bay.
Caution: You might feel initial resistance in sliding out the power supply from its bay.
Do not tilt or twist the supply; this can damage components. Resistance is caused by the
power supply module disengaging from its connector. Use even, steady force to remove
the supply.
