NOTE:
The HP A58x0AF 650W AC power supply and the HP A58x0AF 650W DC power supply are referred to
as the 650W AC power supply and the 650W DC power supply throughout this installation guide.
Installing a power supply
CAUTION:
 Follow the forward inertia of the power supply when inserting it into the chassis, and make sure that the power
supply has firm contact with the connectors on the backplane.
 To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If you encounter
resistance while inserting the power supply, pull out the power supply and insert it again.
 If only one power supply is installed, install a power filler module in the empty power supply slot for good ventilation
of the switch.
To install a 650W AC power supply or 650W DC power supply into the switch:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded.
2. Unpack the power supply and check that the power supply model is correct.
3. Correctly orient the power supply with the power supply slot (see Figure 17), grasp the handle of the
power supply with one hand and support its bottom with the other, and slide the power supply slowly
along the guide rails into the slot.
If you cannot insert the power supply into the slot, re-orient the power supply rather than use excessive
force to push it in.
