6.1 How to Remove a Power Supply
6.1.1 Before You Begin
It is not necessary to power off the system if you are removing a redundant power
supply. For more information, see “About Power Supplies” in your Sun Enterprise
220R Server Owner’s Guide.
If your system has only one power supply, complete this task:
Section 2.1 “How to Power Off the System” on page 54
6.1.2 What to Do
1. Identify the power supply that you want to remove.
2. Unlock the system doors and swing them open.
Turn the keyswitch to the Power-On/Off position. This unlocks the system front
access doors.
3. Loosen the Phillips screw that secures the power supply retaining clip until
you can push the clip upward.
4. Using your thumb, push up the retaining clip until it clears the power supply.
Caution - Keep the thumb holding the retainer clip up clear of the power supply as
you slide it out from its bay.
5. With your other hand, rotate the power supply handle so that it is
perpendicular to the front face of the unit.
