Removing a PSR150 series power supply
To remove a power supply:
1.
Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2.
Disconnect the power cord.
3.
Loosen the captive screws of the power supply with a Phillips screwdriver until they are completely
disengaged.
4.
Grasp the handle of the power supply with one hand and pull it out a little, support the bottom with
the other hand, and pull the power supply slowly along the guide rails out of the slot.
Put away the removed power supply in an antistatic bag or the power supply package bag for
future use.

Install the filler panel to prevent dust and ensure proper ventilation if no power supply is installed
in the slot.
