5.3.2 Uninterruptible Power Supply Monitoring
If the 2H22-08R is connected to an American Power Conversion
Uninterruptible Power Supply (UPS) device for protection against the
loss of power, a connection from the 2H22-08R 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.
Use the Console Cable Kit provided with the 2H22-08R to attach the UPS
to the 2H22-08R COM port as shown in Figure 5-2.
To connect the UPS device to the COM port of the 2H22-08R, proceed as
follows:
1. Connect the RJ45 connector at one end of the cable to the COM port
on the 2H22-08R.
2. Plug the RJ45 connector at the other end of the cable into the
RJ45-to-DB9 male (UPS) adapter, Cabletron Systems Part No.
9372066.
3. Connect the RJ45-to-DB9 male (UPS) adapter to the female DB9 port
on the rear of the UPS device (refer to the particular UPS device’s user
instructions for more specific information about the monitoring
connection).
