v
When the air-baffle assembly is installed in the server, the air-baffle cover is
always closed.
v Microprocessor socket 2 always contains either a microprocessor baffle or a
microprocessor.
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:
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 or scarf 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.
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 server for at least 2 seconds. (This drains static electricity from
the package and from your body.)
v Remove the device from its package and install it directly into the server without
setting down the device. If it is necessary to set down the device, place it back
into its static-protective package. Do not place the device on the server cover or
on a metal surface.
v Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.
Major components of the xSeries 235 Type 8671 server
The orange color on components and labels in your server identifies hot-swap or
hot-plug components. You can install or remove hot-swap or hot-plug components
while the system is running, provided that your system is configured to support this
function.
