B.4. Connecting the UPS to the Subsystem
B.4.1 Connect the PSU Module Power Cords
The three (3) power cords shipped with the subsystem must be plugged into the
power cord sockets in the rear of the PSU modules. The plug at the other end of the
power cord must be inserted into a socket on the UPS. Please refer to the
documentation that came with your UPS device to determine the location of these
sockets. The UPS must then be connected to main power.
B.4.2 Set the Baud Rate
The default baud rate for the COM2 serial port is 38400 and must be changed to 2400
or other rate as specified by the UPS specifications. To see how to change the baud
rate, please refer to the
Generic Operation Manual
that came with the subsystem.
B.4.3 Connect COM2
The separate audio-jack-to-DB9 serial cable connects the COM2 ports on the
controller modules to the UPS directly. The cable transmits UPS status updates to the
controller modules and will in turn determine the write policy of the controller
module. To connect the serial communication cable to the subsystem controller,
insert the audio jack connector on one end of the cable into the COM2 port on the
controller module. To see how to connect the DB9 connector to the UPS, please refer
to the documentation that came with your UPS.
