1.3 Handling AMCs
Caution – The system is sensitive to static electricity. To prevent damage to the
assembly, always connect an antistatic wrist strap between you and the system.
Avoid touching areas of integrated circuitry. Static discharge can damage these
circuits.
An antistatic wrist strap and a conductive foam pad is strongly recommend for
handling AMCs when installing or upgrading a system. Electronic components, such
as disk drives, computer boards, and memory modules can be extremely sensitive to
electrostatic discharge (ESD). After removing the component from its protective
wrapper or from the system, place the component flat on a grounded, static-free
surface (and, in the case of a board, component side up). Do not slide the component
over any surface.
If an ESD station is not available, you can avoid damage resulting from ESD by
wearing an antistatic wrist strap (available in the shipkit and at electronics stores)
that is attached to an active electrical ground. Note that a system chassis might not
be grounded if it is unplugged.
Caution – Dangerous voltages, capable of causing injury or death, are present in
this equipment. Use extreme caution when handling, testing, and adjusting within a
system.
Caution – Do not flex the AMCs; the surface-mounted components can break if the
AMC is bent.
Our suppliers take significant steps to ensure that there are no bent pins on the
backplane or connector damage to the AMCs prior to leaving the factory. Bent pins
caused by improper installation or by AMCs with damaged connectors could void
the warranty for the backplane or boards.
To minimize the amount of AMC flexing, observe the following precautions:
■ When removing an AMC from an electrostatic discharge bag, keep the AMC
vertical until you place it on the electrostatic discharge mat.
■ Do not place an AMC on a hard surface. Use a cushioned antistatic mat. The
AMC connectors and components have very thin pins that bend easily.
■ Be careful of small parts located on the component side of an AMC.
