3.4.1.3 Write Protection (Disk Drives with 68-Pin SCSI Connector)

To configure Write Protection for the drive, install a jumper across pin pair 19 / 20
on the Secondary Option Connector (Figure 3-4). To disable Write Protection on the
drive, remove the jumper.

3.4.1.4 Spin Up (Disk Drives with 68-Pin SCSI Connector)

Atlas 10K II Ultra 160/m SCSI drives have three Spin Up modes:
Option 1:
Option 2:
Option 3:

0 = Jumper Not Installed
1 = Jumper Installed
Spin up immediately when power is applied: Verify that no jumper
is installed across pin pair 11 / 12 (GND / Spin Delay) of the
Secondary Option connector (Figure 3-4).
Spin up after a predetermined delay following power on: Install
jumpers across pin pair 11 / 12 (GND / Spin Delay) and across pin
pair 21 / 22 (GND / Stagger Spin) on the Secondary Option
connector (Figure 3-4). Set the delay parameters with the MODE
SELECT command, Quantum-Unique 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.
Spin up on START STOP UNIT command: Install a jumper across
pin pair 11 / 12 (GND / Spin Delay) and remove any jumper from
pin pair 21 / 22 (GND / Stagger Spin), if a jumper is installed there,
on the Secondary Option connector (Figure 3-4).
