Use the PGND cable provided with the switch to connect the grounding strip in the equipment room.
Otherwise, the grounding effect may not be ensured, which easily causes damage to the switch.
Installing a Power Module
Each S5820X series provides two power module slots on its rear panel. Hot swappable power module
slot 1 is empty when the switch is shipped, and hot swappable power module 2 is installed with a filler
panel. You can select one or two power modules for your switch as needed. For details about optional
power modules, refer to
Hot Swappable Power Modules on page 1-13 .
This section describes how to install and remove the power module and the power cord. To prevent
damage to the device and personal injury, follow the installation and power-on procedure illustrated in
Figure 3-17 and the power-off and removal procedure illustrated in Figure 3-18 .

Installing the Power Module
The procedures of installing any type of hot-swappable power module into the S5820X series are
similar. The installation procedure is as follows:
Step1
Wear an ESD-preventive wrist strap, ensure a good skin contact and make sure that the
ESD-preventive wrist strap is properly grounded.
Step2
Take the power module from the package and check that the power module model is as required.
Step3
Face the slot into which the power module is to be inserted..
Step4
Insert the power module with the upside up (if you insert it with the upside down, the insertion is not
smooth because of the specific structure design of the power module and slot). Grasp the handle of the
module with one hand and hold the module bottom with the other, and then slide the module slowly
along the guide rails into the slot (see callout 1 in
Figure 3-19 ).
Step5
Fasten the captive screw on the power module clockwise with a Philips screwdriver until the power
module is fixed into the chassis (see callout 2 in
Figure 3-19 ).
