For the dual AC power supply note the following:
• The LED on the left side of the chassis is only connected when the dual AC is
used. It is not relevant to the single AC power connection.
• If only a single socket is connected to the AC power, (while the other plug is
left unconnected) the chassis LED (on the left side) is lit red, indicating that
one of the dual power inlets is disconnected.
• When both the AC power cables are connected, one of the plugs can be
disconnected under power without affecting operation, in which case the
chassis left LED is lit red.
• UPS can be connected to either (or both) of the AC connections.
• The dual AC connections operate in a 1+ 1 configuration and provide load-
sharing redundancy.
• Each of the dual power cables can be connected to different power phases.
Connecting the DC Power Supply
To connect the V7122 gateway to a DC power supply use one of these two options:
DC Terminal block with a screw connection type.
DC Terminal block with a crimp connection type.
To connect DC power using a DC terminal block screw connector, follow these 3 steps:
1 Create a DC cable by inserting two 14-16 AWG insulated wires into the supplied adaptor
(see
Figure 9) and fasten the two screws, each one located directly above each wire.
2 Connect the two insulated wires to the correct DC power supply. Ensure that the
connections to the DC power supply maintain the correct polarity.
3 Insert the terminal block into the DC inlet located on the V7122 gateway.
