• Ground yourself to the drive whenever the drive
electronics are or will be exposed. Connect yourself
to ground with a wrist strap (Seagate part number
12263496). Connection may be made to any grounded
metal assembly. As a general rule, remember that you
and the drive electronics must all be grounded to avoid
potentially damaging static discharges.
• Turn off the power before removing or installing the
DC power cable.
• Do not remove any circuit boards from the drive.
• Never use an ohmmeter on any circuit boards.
• When installing the drive on a carrier or tray, dis-
charge the carrier or tray prior to inserting it into the
system.
