Spin up immediately when power is applied. Verify that no jumper is installed
acr oss the Delay Spin pin pair of the J3 Option Header.
Spin up after a predetermined delay following power on: Install the jumper across
pin pai r 2 1/22 (GND/Stag ger S pin) on the J3 Opti on Hea der . S e t th e de la y
para me te rs w i th th e MOD E SELECT co m m and, Maxto r (Vendor) Specia l
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-d rive in stallations .
Spin up on START STOP UNIT command: Install the jumper across pin pair
11/12 (GND/Delay Spin) on the J3 O ption Header. Remove any jumper
from pin pair 21/22 (GND/Stagger Spin) if a jumper is ins talled there, on the
Secondary Option connector.
Install a jumper across pin pair 13/14 (SE) on t he J3 Option Header) to op erate the
disk dr ive as a single-ended d evice. Remove the SE jumper for LVD operatio n and
moni tor ing of th e DIFF SEN S si g na l .
Busy and Fault status of the drive can be monitored remotely by connecting a
remote (external) Busy and/or remote Fault displa y LEDs to the appropri ate pins
on the J3 Option Header or the J1 Option Connector.
On the J3 Option Header, connect the cathode side of the remote Busy LED to pin
18, Busy Out. Connect the anode side of the LED to pin 17, +5V.
On the J1 Option Connector, conne ct the cathode side of the rem ote B usy LED
to pin 8, Busy Out. Connect the anode side of the LED to pin 11, +5V.
On the J3 Option Header, connect the cath ode side of the remote Fa ult LED to
pin 9, Fault LED. Connect the anode side of the LED to pin 17, +5V .
On the J1 Option Connector, conne ct the cathode side of the remote F ault LED
to pin 2, Fault LED. Connect the anode side of the LED to pin 11, +5V.
Wide Data Transfer (WDTR) negations can be limited to 8-bit transfers by
installing a jumper across pin pairs 23/24 (No Wide) of the J3 Option Header. This
can also be done by setting byte 5, bit 4 in the Maxtor (Vendor) Unique Mode Page
(39h) via the Mode Select command (15h).
