The switch comes with power supply slot PWR1 empty and power supply slot PWR2 installed with a
filler module.
For more information about the power supplies available for the switches, see "
Figure 21 Installation procedure
Figure 22 Removal procedure
Installing a power supply
CAUTION:
•
Follow the forward inertia of the power supply when inserting it into the chassis, and make sure
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 a hard resistance while inserting the power supply, pull out the power supply and
insert it again.
•
As a best practice for heat dissipation, make sure each empty power module slot is installed with
a filler panel.
The installation procedure is the same for power supplies of different models. The following
procedure installs a PSR250-12A power supply on an HPE 5710-54HF switch.
To install a power supply:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Remove the filler module from the target power supply slot, if any, as shown in
Figure 23 Removing the filler module from a power supply slot
3.
Unpack the power supply and verify that the power supply model is correct.
4.
Correctly orient the power supply with the power supply slot (see
). 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.
The slot is foolproof. If you cannot insert the power supply into the slot, re-orient the power
supply rather than use excessive force to push it in.
