23Cabling and Configuration Connecting Power
Connecting Power
The NSG comes with either an AC power supply or a –48 VDC power
supply. Follow the instructions appropriate to your power supply.
Note: Reliable earthing of rack-mounted equipment should be
maintained.Particular attention should be given to supply connections
other than direct connections to the branch circuit.
Connecting the AC Power Cable
If your NSG has the AC power line cord, connect the power cord to the
power plug on the NSG back panel, and connect the power cord to the
power outlet.
The power supply automatically senses the input voltage.
Connecting the –48 VDC Power Supply
If your NSG has the optional –48 VDC power supply, see
Appendix B, “Wiring the –48 VDC Power Supply,” for instructions to wire
the power supply.
When you connect the NSG to the power supply, the boot up procedure
starts. During boot up the following messages appear in the control panel
display:
Power up - indicates the beginning of the procedure.
Booting... - indicates the booting stage.
Loading... - indicates that the unit loads the application.
Once boot up is complete the Power Up screen appears in the control
panel display and you may start configuring the NSG. The Power Up
screen shows the company’s name, type of NSG and a default IP address.
