NOTE:
•
The S3600V2-28TP-SI and S3600V2-52TP-SI do not support DC power supply.
• No DC power cord is supplied with the S3600V2 Switch Series.
The S3600V2 Switch Series provides DC power input.
• Non PoE switches (S3600V2-28TP-EI, S3600V2-52TP-EI, and S3600V2-28F-EI) can be powered by
the –48VDC power supply in the equipment room.
• PoE switches (S3600V2-28TP-PWR-EI, S3600V2-28TP-PWR-SI, S3600V2-52TP-PWR-EI, and
S3600V2-52TP-PWR-SI) can be powered by an RPS power source.
The procedures for connecting a –48 VDC power source in the equipment room and an RPS power
source are similar.
Follow these steps to connect a DC power cord:
Step1 Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded.
Step2 Keep the upside of the DC plug on top and plug it in the DC receptacle (see callout 1 in Figure 28 ). (If
you plug it upside down, the insertion is not smooth because of the specific structure design of the DC
receptacle and the DC plug.)
Step3 Use a flat-blade screwdriver to fix the two screws on the DC plug to secure the plug to the DC receptacle
(see callout 2 in
Figure 28 ).
Step4 Connect the other end of the DC power cord to the –48 VDC power source in the equipment room or the
RPS power source.
Step5 Check the power LED (PWR) on the front panel. If the LED is on, the power cord is properly connected.
If you also connect an AC power cord to the switch, check the RPS LED to confirm the RPS input status.

CAUTION:
Pay attention to the positive (+) and negative (-) marks on the power cord to avoid connection mistakes.
Verifying the installation
Before powering on the switch, check that:
