5.3.4 Monitoring an Uninterruptible Power Supply
If the 2E43-51 is connected to an Uninterruptible Power Supply (UPS)
device for protection against the loss of power, a connection from the
2E43-51 COM port to the UPS can be made to monitor the power status
of the UPS. To use the COM port for this purpose, it must be reconfigured
to support the UPS connection using the procedure described in
Section 5.7.10. Refer to the UPS documentation for details on how to
access the status information.
The Console Cable Kit provided with the 2E43-51 is used to attach the
UPS to the 2E43-51 COM port as shown in Figure 5-2.
To connect the UPS device to the COM port of the 2E43-51, proceed as
follows:
1. Connect the RJ45 connector at one end of the cable to the COM port
on the 2E43-51.
2. Plug the RJ45 connector at the other end of the cable into the
RJ45-to-DB9 male (UPS) adapter.
3. Connect the RJ45-to-DB9 male (UPS) adapter to the female DB9 port
on the rear of the UPS device (see the particular UPS device’s user
instructions for more specific information about the monitoring
connection).
