Removable Power Supply and Fan

Installing a PWR05 or FAN03
1. If there is a PSU, fan or blanking plate in the bay you wish to install the unit,
first remove the old unit, following the steps described in section
“Removing a Power Supply Unit or Fan” on page 15 .
2. Insert the new PSU or chassis fan module, and carefully slide it into the bay.
If you are installing a PSU, unlock the latch on the PSU first by loosening the
captive screw.
Insert the PSU or fan module slowly, being sure to keep it straight. Firmly
press the unit until the faceplate engages, or nearly engages, the chassis.
Forcing a misaligned unit into the bay may damage both the unit and chassis.
3. Secure the unit in the switch by tightening the captive screw(s) on the
faceplate. On the PWR05, use a screwdriver to tighten the captive screw
such that a screwdriver will be required to remove the PSU at a later date.
