D.4 Connecting the UPS to the Subsystem
D.4.1 Connect the PSU Module Power Cords
The two (2) power cables 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 cable must be inserted into a socket on the UPS. (See
Figure D-2) Please refer to the UPS manual to determine the location of
these sockets. The UPS must then be connected to main power.
D.4.2 Set the Baud Rate
The default baud rate for the COM 2 serial port is 38400 and must be
changed to 2400. For instructions on changing the baud rate, please refer to
the SCSI to SATA RAID Subsystem’s Operation Manual that came with
the subsystem.
D.4.3 Connect COM2
The separately purchased audio-jack to DB9 serial cable connects the
COM2 port on the controller module to the UPS directly. (See Figure D-2)
The cable transmits UPS status updates to the controller module 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.
