5.3.2 Connecting an Uninterruptible Power Supply
If the 6C105 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 6C105 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 6E12X-26 and 6E13X-25
as follows:
1. Connect the RJ45 connector at one end of the cable to the COM port
on the 6E12X-26 and 6E13X-25.
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).
