Working inside the server with power on
Your server is designed with special features that make it highly available. These
features include hot-plug PCI expansion slots and hot-swap fans. You can add or
replace PCI adapters (if supported by your operating system) or replace a fan that
no longer functions. In the past, you would need to turn off the server and
disconnect power to perform these operations. With the hot-plug features, you now
can remove the cover of your server with the power on.
Your server is designed to operate safely while turned on with the cover removed.
Here are some simple guidelines to follow when you work inside a server that is
turned on:
Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before
working inside the server; do not wear cufflinks while you are working inside the
server.
Do not allow your necktie to hang inside the server.
Remove jewelry, such as bracelets and loose-fitting wrist watches.
Remove items from your shirt pocket (such as pens or pencils) that could fall
into the server as you lean over it.
Take care to avoid dropping any metallic objects, such as paper clips, hair pins,
or screws, into the server.
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:
Limit your movement. Movement can cause static electricity to build up around
you.
Handle the device carefully, holding it by its edges or its frame.
Do not touch solder joints, pins, or exposed printed circuitry.
Do not leave the device where others can handle and possibly damage the
device.
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.)
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.
Take additional care when handling devices during cold weather as heating
reduces indoor humidity and increases static electricity.
