6.8.3 Connector and jumper description

A jumper is used to designate the drive address as either master or slave. The jumper setting method is described in
section "Drive address setting."
Connector specifications are included in section "Interface connector."

6.8.4 Drive mounting

The drive will operate in all axes (six directions) and will stay within the specified error rates when tilted ±5
degrees from these positions.
Performance and error rate will stay within specification limits if the drive is operated in the other permissible ori-
entations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run verti-
cally and vice versa.
The recommended mounting screw torque is 0.3±0.05 Nm.
The recommended mounting screw depth is 3.0±0.3 mm for bottom and 3.5±0.5 mm for horizontal mounting.
The user is responsible for using the appropriate screws or equivalent mounting hardware to mount the drive
securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation.

6.8.5 Load/unload mechanism

The head load/unload mechanism is provided to protect the disk data during shipping, movement, or storage. Upon
power down, the heads are automatically unload from the disk area and the locking mechanism of the head actuator
will secure the heads in unload position.

6.9 Vibration and shock

All vibration and shock measurements recorded in this section are made with a drive that has no mounting attach-
ments for the systems. The input power for the measurements is applied to the normal drive mounting points.

6.9.1 Operating vibration

The drive will operate without a hard error while being subjected to the following vibration levels.
6.9.1.1 Random vibration
The test is 30 minutes of random vibration using the power spectral density (PSD) levels shown below. .
The vibration test level is 6.57 m/sec2 RMS (Root Mean Square) (0.67 G RMS).
