Removing a PSR150 power module
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Disconnect the power cord.
3. Loosen the captive screws of the power module with a Phillips screwdriver until they are completely
disengaged.
4. Grasp the handle of the power module with one hand and pull it out a little, support the bottom
with the other hand, and pull the power module slowly along the guide rails out of the slot.
Put away the removed power module in an antistatic bag or the power module package bag for
future use.
5. Install the filler panel to prevent dust and ensure good ventilation if no power module is installed
in the slot.
