•
Do not touch the connector pins or the printed circuit board. Do not
touch the printed circuit cable between the circuit board and the
head/disc assembly.
•
Avoid wool or synthetic clothing, carpeting, plastics and Styrofoam;
these items cause static discharge.
•
Do not remove the factory-installed labels from the drive or cover them
with additional labels. If you do, you may void the warranty. Some
factory-installed labels contain information needed to service the
drive. Others are used to seal out dirt and contamination.
2.3 Hot-plugging
If there is more than one SCSI device daisy-chained on the bus, you can
connect and disconnect the drive I/O and power connector if the following
conditions are met:
•
The drive you are disconnecting (or connecting) is not the device
supplying terminator power or terminating resistance to the bus.
•
During hot-plugging, do not add or remove terminator power or
resistors from the bus.
•
During hot-plugging, do not use the bus for I/O transactions. If you are
installing a drive on the bus, there must be no I/O transactions until
the drive is connected and ready. If you are removing a drive from the
bus, there must be no I/O transactions until the drive is completely
disconnected.
To avoid damage to the disc and head, the spindle must be completely
stopped and the heads must be parked before you remove the drive from
the system. There are two ways to stop the spindle and park the heads:
•
If the drive is not configured to use the remote start/stop feature,
disconnect the DC power cable from the drive DC power connector
and wait 30 seconds.
•
If the drive is configured to use the remote start/stop feature, issue the
SCSI stop command and wait 30 seconds.
