Disabling Spin-Up at Power On - CFP2107W
A jumper in the E5 location, disables spin up on power-on for applications where
spin up sequencing is necessary. Disabling spin up on application of power can
also be enabled by setting the DSPN bit in MODE SELECT page 00
H
(Vendor
Specific Parameters). The Host must issue a START UNIT command to cause
the drive to spin up. Refer to the Eleventh Generation SCSI Technical
Reference Manual for additional information regarding the MODE SELECT and
START/STOP UNIT commands. Refer to Figure 4-6 for the location of the
Disable Spin jumper E5 and the option header.

Note: In = Ground or TTL Low and Out = Open or TTL High. The
odd numbered pin is grounded and the even numbered pin carries
the signal.
Delaying Spin Up at Power On - CFP2107W
A jumper in the E6 location, delays spin up on power-up by the value of the
drive's SCSI ID multiplied by 4 seconds (i.e. SCSI ID 4 will delay 16 seconds).
Delaying spin up on application of power can also be enabled by setting the
SDLY bit in MODE SELECT page 00
H
(Vendor Specific Parameters). Refer to
the Eleventh Generation SCSI Technical Reference Manual for additional
information regarding the MODE SELECT command. Refer to Figure 4-6 for
the location of the Delayed Spin jumper, E6.
