Prevent Damage To Components - HP D5970A - NetServer - LCII Manual

Chapter 1
WARNING
Ensure site electrical circuits have reliable earth grounding.
Never operate products in any rack enclosure with the ground
connector disconnected. Although leakage current from any
one device may be minimal, cumulative leakage current of
equipment mounted in a rack may exceed 5mA, and could
reach 15mA. This level of current can be dangerous, unless a
reliable earth ground is in place. Thus, reliable ground
circuit continuity is vital to safe operation of this system.
WARNING
Prevent shock by disconnecting power and telephone cords
when you service or install components.

Prevent Damage to Components

CAUTION
Rack optimized products are sensitive to static electricity
(ESD). When installing components, take precautions against
ESD damage. Wear a wrist-strap and use a static-dissipating
work surface connected to the server chassis when handling
printed circuit boards, memory devices, and processor chips
or modules. Ensure that the metal of the wrist-strap contacts
your skin and that the alligator clip is attached to a static-
neutral surface.
CAUTION
Power up the components one at a time as recommended in
the section titled "Power Up Sequence" to minimize current
inrush.
