Working inside the server with the power on
Your server supports hot-plug, hot-add, and hot-swap devices and is designed to
operate safely while turned on with the cover removed. Follow these guidelines 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 cuff links while you are working inside the
server.
• Do not allow your necktie or scarf to hang inside the server.
• Remove jewelry, such as bracelets, necklaces, rings, 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.
• 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 package 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 static-protective 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 because heating
reduces indoor humidity and increases static electricity.
