Connecting the RPS Power Cord
Connect RPS power cords of S5120-28C-EI, S5120-52C-EI, S5120-24P-EI, and S5120-48P-EI
The S5120-28C-EI, S5120-52C-EI, S5120-24P-EI and S5120-48P-EI can work with RPS500-A3 using
its +12 V/10.5 A output and a 0404A03C power cord.
Follow these steps to connect an RPS power cord to the switch:
Step1
Connect one end of the chassis ground wire to the grounding screw on the rear panel of the chassis and
the other end to the ground as near as possible.
Step2
Loosen the captive screws on the RPS receptacle protective cover and remove the protective cover, as
shown in Figure 3-23. (If you do not use the 12 VDC RPS interface, install the protective cover.)

Step3
Keep the upside of the 12 VDC RPS plug on top and plug it in the RPS DC receptacle (see callout 1 in
Figure 3-24). (If you plug it with the upside down, the insertion is not smooth because of the specific
structure design of the RPS DC receptacle and the RPS plug.)
Step4
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 3-24).

Step5
Connect the other end of the 12 VDC RPS power cord to the external RPS power supply system.
Step6
Check whether the RPS LED on the front panel of the switch is ON. If yes, the power is properly
connected.
