HP ProCurve 4000M Installation Manual page 25

Insert the power supply into the
opening, lower it until it rests on the
bottom of the switch chassis, then
slide it all the way in until it connects
to the switch. The power supply
face plate will be flush with the back
of the switch.
Once the power supply is installed, make sure you tighten the four retaining
screws that hold it in place. The screws can be tightened with either a flat-
bladed or Torx T-10 screwdriver. Be careful not to overtighten the screws.
