Connecting to Power
Connecting to a Redundant Power Supply
The DPS-500 connects to the 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.
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.
CAUTION
:
do not connect the RPS to AC power before the DC power cable is
connected. This might damage the internal power supply.
