Connecting to a Redundant Power Supply
The DGS 3620 Series switch connects to the Master Switch using a 14-pin DC power cable. A standard, three-
pronged AC power cable connects the redundant power supply to the main power source.

–5 Connecting a DGS-3620 Series Switch to the DPS-500 (28SC, 28TC, 52T)
1. Insert one end of the 14-pin DC power cable into the port on the switch and the other end into the redundant
power supply.
2. Using a standard AC power cable, connect the redundant power supply to the main AC power source. A
green LED on the front of the DPS-500 will glow to indicate a successful connection.
3. Re-connect the switch to the AC power source. The LED indicator will show that a redundant power supply is
now in operation.
4. Do not make any changes on the switch.
Note:
See the DPS-500 documentation for more information.
CAUTION:
The DGS-3620-28TC-DC/28SC-DC
doesn’t support any redundant power system.
Only the DGS-3620-28TC, DGS-3620-28SC & the DGS-3620-52T use DPS500. The DGS-3620-
28PC and the DGS-3620-52P use the DPS700.
