System Reliability Guidelines; Handling Static-Sensitive Devices - IBM x3455 - System - 7984 User Manual

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that the following
requirements are met:
v The CD or DVD drive bay has a drive or a filler panel and electromagnetic
v There is adequate space around the server to allow the server cooling system to
v You have followed the cabling instructions that come with optional adapters.
v All fans are operating correctly.
v You do not operate the server without the air baffles installed. Operating the
v Microprocessor socket 1 always contains a microprocessor and heat sink.
v Microprocessor socket 2 always contains either a microprocessor baffle or a
v No dual inline memory modules (DIMMs) are installed in connectors 7 through 12
v Each installed adapter is of the same type (PCI Express or Hyper Transport) as
v You do not install a graphics adapter. Operating the server with an unsupported

Handling static-sensitive devices

Attention:
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v Limit your movement. Movement can cause static electricity to build up around
v The use of a grounding system is recommended. For example, wear an
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.

work properly. Leave approximately 50 mm (2.0 in.) of open space around the
left and right sides of the server. Leave approximately 166 mm (6.54 in.) of open
space around the rear of the server. Do not place objects in front of the fans or
air baffles. For proper cooling and airflow, replace the server cover before you
turn on the server. Operating the server for extended periods of time with the
server cover removed might damage server components.
