D.4 Connecting the UPS to the SubsystemD.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.
