1.3 Determining Which DSSI ID Numbers Are Available
A DSSI ID number must be designated for the first drive installed in a BA42
expander; the DSSI IDs for the remainder of the drives in the expander will be
set automatically in increments of one, beginning with the number assigned to
the first drive.
Numbers that can be used range from 0 to 7 (up to seven DSSI drives can be
connected to a given DSSI connector on the system unit); each number may
be used only once via that connector. To find out what DSSI ID numbers are
available, see the option installation instructions in the installation guide or
user’s guide for the system.
After determining the DSSI ID number to be assigned to the first drive, use
the DSSI ID switches on the rear of the expander box to set the ID to that
number (see Section 1.4).
