Step2
Keep the upside of the RPS plug on top and plug it in the RPS DC receptacle (see callout 1 in Figure
3-25). (If you plug it upside down, the insertion is not smooth because of the specific structure design of
the RPS DC receptacle and the RPS plug.)
Step3
Use a flat-blade screwdriver to fix the two screws on the RPS plug clockwise to secure the plug to the
RPS DC receptacle (see callout 2 in Figure 3-25).

Step4
Connect the other end of the RPS DC power cord to the external RPS power supply system.
Step5
Check whether the RPS LED on the front panel of the switch is ON. If the LED is ON, it shows the power
cord is properly connected.
Installing an Interface Module
Each S5120-28C-EI/S5120-52C-EI/S5120-24P-EI/S5120-48P-EI switch provides two interface module
slots on the rear panel. For details about optional interface modules, refer to Optional Interface Modules
on page 1-15.
The installation and removal of various interface modules are similar. This section describes the
installation and removal of the Dual-Port 10 GE SFP+ Interface Module (LSPM2SP2P) for illustration.
Installing an Interface Card
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
Loosen the mounting screws of the filler panel on the interface module slot of the switch's rear panel
with a Phillips screwdriver and remove the filler panel.

Hold the fastening screws on the front panel of the SFP+ interface module, and gently push the
interface module in along the slot guide rail until the interface module is in close contact with the switch.
