System Reliability Considerations; Handling Static-Sensitive Devices - IBM xSeries 200 Hardware Maintenance Manual

v Remove jewelry, such as bracelets, necklaces, rings,
and loose-fitting wrist watches.
v Remove items from your shirt pocket (such as pens or
pencils) that could fall into the server as you lean over
it.
v Avoid dropping any metallic objects, such as paper
clips, hair pins, or screws, into the server.

System reliability considerations

To help ensure proper cooling and system reliability, make
sure that:
v Each of the drive bays either has a drive, or a filler
panel and electromagnetic compatibility (EMC) shield
installed.
v There is space around the server to allow the server
cooling system to work properly. Leave about 127 mm
(5 in.) of space around the front and rear of the server.
v Cables for optional adapters are routed according to the
instructions that are provided with the adapters.
v A failed fan is replaced within 1 hour.

Handling static-sensitive devices

Attention:
devices and your system. To avoid damage, keep
static-sensitive devices in their static-protective bag 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 anti-static package, touch it
to an unpainted metal part of the system unit 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 system unit without setting it down. If it
is necessary to set the device down, place it on its
static-protective package. (If your device is an adapter,
place it component side up.) Do not place the device on
your system unit cover or on a metal table.
