3.4.3
Connecting the Power Supply
Connect the Mediant 2000 to the power supply using one of the following methods:
3.4.3.1
Connecting the AC Power Supply
When using a single AC power cable:
Attach one end of the supplied 100/240 VAC power cable to the rear AC socket and connect the
other end to the correct earthed AC power supply.
When using a dual AC power cable:
Attach one end of the supplied 100/240 VAC power cables to the rear AC sockets and connect
the other end to a separate earthed mains circuits (for power source redundancy).
Note:
3.4.3.2
Connecting the DC Power Supply
To connect the Mediant 2000 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.
When using a DC terminal block screw connector, take these 3 steps:
Create a DC cable by inserting two 14-16 AWG insulated wires into the supplied adaptor
1.
(refer to
Connect the two insulated wires to the correct DC power supply. Ensure that the connections
2.
to the DC power supply maintain the correct polarity.
Insert the terminal block into the DC inlet located on the Mediant 2000.

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 AC power phases.
