Connecting an Uninterruptible Power Supply
If the DLM6C-AA chassis is connected to an American Power
Conversion (APC) Uninterruptible Power Supply (UPS) for protection
from a loss of power, a connection from the COM port of a module 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
application. This procedure is performed from the General Configuration
screen of the interface module. Section 5.15.11, Configuring the COM
Port, provides detailed instructions on configuring the COM port for UPS
applications. Refer to the UPS documentation for details on how to access
the status information.
Use the Console Cable Kit provided with the DLM6C-AA chassis to
attach the UPS to the module COM port as shown in Figure 5-2.
Connect the UPS device to the COM port of the DLE28-MA as follows:
1.
Connect the RJ45 connector at one end of the cable to the COM port
on the DLE28-MA.
2.
Plug the RJ45 connector at the other end of the cable into the
RJ45-to-DB9 male (UPS) adapter, Cabletron 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).
