4 4Setting up a SCSI-to-SCSI controller using RS-232
1. Connect the RS-232 port of the SCSI-to-SCSI controller to a
null modem using the appropriate RS-232 cable. Do the
same to the serial interface of the local host. If your local
host has more than one serial interface, write down the
corresponding port number of the selected port (that is,
COM1, COM2, etc.).
2. Configure the RS-232 serial communication port of the local
host to correspond to that of the interface on the controller.
You will only need to set the baud rate; the GUI RAID
Manager automatically sets the other communications
parameters. If you want to modify the baud rate setting on
the controller, use the on-board console interface or the GUI
RAID Manager. For information on the latter, see Chapter
4, Array Management.
Your hardware should be set up as shown in the following
