Jumper Setting
==============
Drive Address Setting
---------------------
A jumper is available at the interface connector to determine the
drive address.
Using Cable Selection, the drive address depends on the condition of
pin 28 of the AT interface cable. In the case when pin 28 is ground
or low, the drive is a Master. If pin 28 is open or high level, the
drive is a Slave.

Mounting Orientation
--------------------
The disk drive shall operate in all axis (6 Directions). The disk
drive shall operate within specified error rates when tilted +/-5
degrees from these positions.
Performance and error rate must stay within specification limits if
the disk drive is operated in the other permissible orientations from
which it was formatted. Thus a disk drive formatted in a horizontal
orientation must be able to run vertically and vice versa.
The recommended mounting screw torque is 3 +/- 0.5 kgf.cm.
The recommended mounting screw depth is 3.5 +/- 0.5mm for bottom and
5.0 +/- 0.5mm for horizontal mounting.
The system is reponsible for mounting the drive securely enough to
prevent from excessive motion or vibration of the drive at seek
operation or spindle rotation, using appropriate screws or equivalent
mounting hardware.
The vibration test and shock test are to be conducted with the
drive mounted to the table using bottom four screws.
Landing Zone and Lock
---------------------
A landing zone on the disk, not on the data area of the disk, is
provided to protect the disk data during shipping, movement, or
storage. After power down, a head locking mechanism secures the heads
in this zone.
Cabling
-------
The maximum cable length from the host system to the HDD plus
circuit pattern length in the host system shall not exceed 18 inches.
Interface Connector
-------------------
The signal connector for AT Attachment is designed to mate with
Dupont part number 69764-044 or equivalent.
5V Power (Pins 41/42 of the Interface Connector)
------------------------------------------------
There are two input pins for +5V power supply, +5V LOGIC, pin 41 and
+5V MOTOR, pin 42. +5V LOGIC is connected to the internal logic
circuits and +5V MOTOR is connected to the spindle motor and motor
driver.
It is possible to turn on and off +5V LOGIC by an external switch
circuit to reduce power consumption to the least possible. In this
mode, a voltage drop out due to the motor spin up current can be
reduced by connecting +5V MOTOR line into the system power source
directly.
If the above power management is used, all signal lines that will be
electrically active in the host system while the drive is
disconnected from power line shall be isolated by Three-State line
drivers. Internal leakage through ESD protection circuit may pull
down LPUL (least Positive Up Level) of logic signal below the spec.
Use both lines in parallel, for regular drive applications.

are repported to the host system as non-recoverable errors.
Warranty
--------
The warranty will be covered by contracts.
Identification Labels
---------------------
The following labels are affixed to every drive.
1. A label placed on the top of the HDA contains the statement "Made
by IBM" or equivalent, Part number, and MLC number.
2. A bar code label placed on the disk drive is based on user
request. The location is to be designated in the drawing.
3. Labels containing the vendor's name, disk drive model number,
serial number, place of manufacture and UL/CSA certificates.
Except for the bar code, the labels may be integrated.
