[1] Do not mix “W,” “WD,” and “LW” model drives on the daisy chain.

However, an “LW” drive may operate on a “W” bus if the drive oper-
ates only in the single-ended I/O transmission mode. Install the
“LVD” jumper shown in Figure 16 to force single-ended I/O opera-
tion. The external terminator [3] will be required on the “LW” drive if it
is the last drive or only drive on the I/O daisy chain.

[2] “X” means up to 15 or the maximum allowable number of devices on

the SCSI bus. See Table 4a and system documentation.
