While a drive is powering up and spinning up, the controls and indicators have slightly

modiﬁed meanings, as described in Section 5.2.

Each control set for a disk drive position contains indicators and buttons and indicators for:

Run Fault conditions Port A

Write protection Unit number selection Port B

You can set most switches by pushing them in. These switches hold the set position until

released with another push. However, the Fault/Set No. switch is a momentary pushbutton.

When pressed and held, it is set; when released, it is not set.

The following table explains the functions of the switches and indicators:
