Electrostatic discharge precautions
Static electricity can damage the storage system’s static-sensitive
components.
When performing the service procedures in this document, observe the
following electrostatic discharge (ESD) precautions:
• Wear an antistatic wrist strap at all times when handling any field
replaceable unit (FRU). Clip the end of the wrist strap to the metal frame
of the storage system enclosure. For convenience, a wrist strap is supplied
with the storage system. Do not remove the wrist strap until you have
completed the removal or replacement.
• Before handling any FRU, discharge any static electricity by touching a
grounded surface. Grounded surfaces include static-dissipating mats
(already grounded) or grounded workstations.
• Remove all plastic, vinyl, and foam material from the work area.
• Do not remove a FRU from its antistatic protective bag until you are ready
to install it.
• Handle any card FRU only by its edges and avoid touching the components
or circuitry.
• Do not slide a FRU over any surface.
• Limit body movement (which builds up static electricity) during the
removal and replacement of a FRU.
• To avoid electric shock when performing a hot replacement of a part, do
not wear metallic accessories or a watch and avoid touching live parts of
the storage system with a screwdriver or similar tools.
Unpacking replacement components
Unpack replacement components in a dry location that is not exposed to
moisture, direct sunlight, dust, and temperature extremes. If the part to be
added has been exposed to high or low temperature during transport, the
part might not operate properly.
Follow appropriate power on and power off work
procedures
If a replacement procedure requires power off and power on steps, follow the
steps carefully to ensure the security of data.
After powering off the storage system, remove the power cables from the two
power supply units on the storage system.
