Removing a PSR720-56A/PSR1110-56A power supply
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Disconnect the power cord.
3. Press the latch towards the handle, and pull the power supply along the guide rails until it is
part-way out.
4. Grasp the handle of the power supply with one hand, 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.
5. Install the filler panel to prevent dust and ensure good ventilation if no power supply is installed in
the slot.
