• You do not operate the server without the air baffle or the fan filler installed. Operating the server without
the air baffle or the fan filler might cause the microprocessor to overheat.
Note:
The air baffle comes with the microprocessor 2 expansion board option.
• Microprocessor socket 2 always contains either a socket cover or a microprocessor and heat sink.
• You have installed the air baffle and fan 2 when you installed the microprocessor 2 expansion board option.
Note:
Do not install the ServeRAID M5120 SAS/SATA adapter in slot 4, 7, and 8 for proper cooling.
Working inside the server with the power on
Guidelines to work inside the server with the power on.
Attention:
Static electricity that is released to internal server components when the server is powered-on
might cause the server to halt, which might result in the loss of data. To avoid this potential problem,
always use an electrostatic-discharge wrist strap or other grounding system when you work inside the
server with the power on.
The server supports hot-plug, hot-add, and hot-swap devices and is designed to operate safely while it
is turned on and the server cover is removed. Follow these guidelines when you work inside a server
that is turned on:
Note:
In order to work inside the server with the power on, you have to disable the power cut-off switch
before removing the server cover.
• Avoid wearing 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 and pencils, that could fall into the server as you
lean over it.
• Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.
Handling static-sensitive devices
Use this information to handle static-sensitive devices.
Attention:
Static electricity can damage the server and other electronic devices. To avoid damage, keep
static-sensitive devices in their static-protective packages until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the following precautions:
• Limit your movement. Movement can cause static electricity to build up around you.
• The use of a grounding system is recommended. For example, wear an electrostatic-discharge wrist
strap, if one is available. Always use an electrostatic-discharge wrist strap or other grounding system
when working inside the server with the power on.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Do not leave the device where others can handle and damage it.
• While the device is still in its static-protective package, touch it to an unpainted metal surface on the
outside of the server for at least 2 seconds. This drains static electricity from the package and from
your body.
