System Reliability Considerations; Handling Static-Sensitive Devices - IBM BladeCenter 4-Port Installation Manual

v For a list of supported options for your BladeCenter unit, refer to
http://www.ibm.com/pc/us/compat/ on the World Wide Web.

System reliability considerations

Attention: To help ensure proper cooling and system reliability, make sure
that:
v Each of the module bays on the rear of the BladeCenter unit has either a
module or filler module installed.
v A removed hot-swap module is replaced with an identical module or filler
module within 1 minute of removal.
v A removed hot-swap blade is replaced with an identical blade or a filler
blade within 1 minute of removal.
v Cables for the optional modules are routed according to the illustrations and
instructions in this document.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system.
To avoid damage, keep static-sensitive devices in their static-protective
packages until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up
around you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the
device.
v While the device is still in its static-protective package, touch it to an
unpainted metal part of the BladeCenter chassis for at least two seconds.
(This drains static electricity from the package and from your body.)
v Remove the device from its package and install it directly into your
BladeCenter unit without setting it down. If it is necessary to set the device
down, place it in its static-protective package. Do not place the device on
your BladeCenter chassis or on a metal table.
v Take additional care when handling devices during cold weather because
heating reduces indoor humidity and increases static electricity.
