Connecting a DC power cord
NOTE:
• The 3600-24 v2 SI Switch and 3600-48 v2 SI Switch do not support DC power supply.
• No DC power cord is supplied with the 3600 v2 Switch Series.
The 3600 v2 Switch Series provides DC power input.
• Non PoE switches (3600-24 v2 EI Switch, 3600-48 v2 EI Switch, and 3600-24-SFP v2 EI Switch)
can be powered by the –48VDC power supply in the equipment room.
• PoE switches (3600-24-PoE+ v2 EI Switch, 3600-24-PoE+ v2 SI Switch, 3600-48-PoE+ v2 EI Switch,
and 3600-48-PoE+ v2 SI Switch) 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:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. 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.)
3. 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).
4. Connect the other end of the DC power cord to the –48 VDC power source in the equipment room
or the RPS power source.
5. 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.
