3.4.3.3 Spin Up for the 80-Pin SCA-2 Connector Versions
Maxtor Atlas 10K V drives have three Spin Up modes:
Option 1 Spin up occurs immediately when power is applied.
Option 2 Drive spin up occurs after a predetermined delay following power on.
Option 3 Drive spin up is controlled by the START STOP UNIT command.
Configure the desired spin up option (Table 3-3) by setting the state of the
DELAY_SPIN (Pin 38) and STAGGER_SPIN (Pin 78) inputs on the 80-pin SCA-
2 connector (Figure 3-4). The states of these signals are set by using either hard-
wired connections at the backplane or backplane logic.

Set the delay parameters with the MODE SELECT Command,
Maxtor (Vendor) Special Function Control Page (39h).The delay is
equal to a user-specified multiplier multiplied by the numerical SCSI
ID of the drive. This will give a staggered spin-up in multiple-drive
installations.
