Starting the Switch
• For DC power supplies, do the following:
1 Turn off the DC power source from your facility's circuit breaker to avoid electric shock hazard.
2 Connect the DC power connector block, which is wired to the DC power source and the earth ground, to the
DC power supply receptacle.
If the power connector block is not wired to the power and grounding cables, see
Connector Block
3 Verify that the ground cable is connected to an earth ground and the other ends of the power cables are connected
to the DC power source.
• For no power redundancy, connect one power supply to one power source.
• For power supply redundancy, connect two power supplies to one or two power sources.
• For grid redundancy, connect each of two power supplies to a different power source.
4 Turn on the power at the circuit breaker for the DC power source.
