Working Inside The Server With The Power On; System Reliability Considerations; Handling Static-Sensitive Devices - IBM xSeries 300 Hardware Maintenance Manual

v Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and any other options that you intend to install.
v Back up all important data before you make changes to disk drives.

Working inside the server with the power on

The server is designed with safety in mind. Follow these guidelines when you
work inside a server that is turned on:
v Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before
working inside the server; do not wear cuff links while you are working inside
the server.
v Do not allow your necktie to hang inside the server.
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: Static electricity can damage electronic 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
