Installing a power supply
1. Wear an ESD wrist strap and make sure it makes good skin contact and is correctly grounded.
2. If the power supply slot is covered by a filler panel, remove the filler panel first.
3. Handle the filler module at the rear of the switch:
{ To install the PSR750-A power supply into the 5800-48G-PoE+ (2 slots) or 5800-48G-PoE+ TAA
(2 slots) switch, remove the filler module (see callout 1 and callout 2 in Figure 33).
{ To install the PSR300-12A, PSR300-12A2, PSR300-12D1, or PSR300-12D2 power supply into
the 5800-48G-PoE+ (2 slots) or 5800-48G-PoE+ TAA (2 slots) switch, make sure the filler
module has been installed at the rear of the switch.
4. Unpack the power supply and verify that the power supply model is correct.
5. Correctly orient the power supply with the power supply slot, 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 (see callout 1 in Figure 34 or Figure 35).
To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If
you cannot insert the power supply into the slot, re-orient the power supply rather than use
excessive force to push it in.
6. Fasten the captive screws on the power supply with a Phillips screwdriver to secure the power
supply in the chassis (see callout 2 in Figure 34 or Figure 35).
If the captive
screw cannot be tightly attached, examine the installation of the power supply.
7. If you install only one power supply, install the filler panel over the empty power supply slot for
good ventilation.
