Installing/Removing a power module (for the S5820X-28S and
the S5820X-28C)
Installing a power module
To install a power module (PSR300-12A series or PSR300-12D series) into the S5820X-28S or
S5820X-28C switch:
1. Wear an ESD-preventive wrist strap, ensure a good skin contact and make sure that the
ESD-preventive wrist strap is corrnctly grounded.
2. If the power module slot is covered by a filler panel, remove the filler panel first.
3. Unpack the power module (for example, a PSR300-12A power module) and check that the power
module model is correct.
4. Correctly orient the power module with the power module slot, grasp the handle of the power
module with one hand and support its bottom with the other, and slide the power module slowly
along the guide rails into the slot (see callout 1 in Figure 48 ). The slot is foolproof. If you cannot
insert the power module into the slot, re-orient the power module rather than use excessive force to
push it in.
5. Fasten the captive screw on the power module with a Philips screwdriver to secure the power
module in the chassis (see callout 2 in
Figure 48 ).

NOTE:
If you install only one power supply, install a filler panel over the empty power supply slot to ensure good
ventilation.
CAUTION:
•
To prevent damage to the power module or the connectors on the backplane, insert the power module
gently. If you encounter a hard resistance while inserting the power module, pull out the power module
and insert it again.
• If the captive screw cannot be tightly fixed, check the installation of the power module.
