Troubleshooting

12-3

Faults fall into three basic categories:

Faults are annunciated on the Human Interface Module (HIM) at the
time they occur. Warnings are not annunciated on the HIM.

To help troubleshoot your 1336 IMPACT drive, the drive logs any
faults or warnings in either the fault or warning queue. The faults and
warnings that are contained in the queues are of either a configurable
type or a non-configurable type.

Several bit-encoded parameters are also available to help troubleshoot
your drive. These parameters are covered later in this chapter and in
the auto-tuning chapter. When viewing these parameters from a HIM,
you should understand how the HIM displays the bits.

When the appropriate parameter is displayed, you will see two rows
of 8 bits represented by zeros and ones. The top row contains (from
left to right) bits 15 through bit 8, and the bottom row contains bits 7
through bit 0.

Refer to Appendix C, Using the Human Interface Module (HIM), for
additional information.
