Common Operations
Starting the PDU
For units without circuit breakers, the PDU output power cannot be turned on and off with a button or switch.
These PDUs are always on when they are plugged in. These PDUs are always off when they are unplugged.
For units with circuit breakers, the circuit breaker controls whether there is output power:
l
If the circuit breakers are on, there is output power, the LCD display is on, and the communications module
is operational.
l
If the circuit breakers are off, there is no output power, but the LCD display is on, and the communications
module is operational.
l
To turn off the PDU completely, unplug it.
To start up the PDU:
1.
For PDUs with detachable power cords.
If the power cord is not connected, connect the power cord to
the PDU. Then, connect the power cord to a power source. Otherwise, go to Step 2.
2.
Does your PDU have a circuit breaker?
-
For PDUs with circuit breakers.
Verify all circuit breakers are in the On position.
-
For PDUs without circuit breakers.
Plug in the power cord.
