Connecting the switch to a +12 VDC output RPS
This section applies to the A5120-24G EI (2 slots), A5120-24G EI TAA (2 slots), A5120-48G EI (2 slots),
A5120-48G EI TAA (2 slots), A5120-24G EI, and A5120-48G EI switches.
To connect these switches to the RPS that provides +12 VDC output:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is properly
grounded.
2. To use the RPS receptacle, loosen the captive screws on the RPS receptacle protective cover and
remove the protective cover, as shown in Figure 26.
(If not using the RPS receptacle, leave the protective cover in place.)

3. The RPS cable provided with the switch has a directional plug that fits the switch's RPS receptacle.
Orient the plug to the RPS receptacle, and insert the plug as shown in Figure 27.
Do not use excessive force. The RPS receptacle is directional. If you cannot insert the plug, re-orient
the plug so it fits.
4. Tighten the screws on the plug with a flat-blade screwdriver.
5. Connect the other end of the power cord to the RPS.
