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:

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.

   

6. Pull out the power supply in a smooth motion until the unit is free of the bay.

   ---

   Note -

   When removing a hot-pluggable power supply, do not disengage and reengage the supply in rapid succession.

   ---

7. If you have removed a redundant power supply and are not replacing it immediately, install a power supply filler panel.

   The filler panel maintains proper system cooling and prevents electromagnetic interference. Align the filler panel over the empty bay and push it into place.

8. Tighten the Phillips screw on the power supply retaining clip.
