Working Inside The Server With The Power On; Handling Static-Sensitive Devices - Lenovo x3300 M4 7382 Installation And Service Manual

• You have replaced a failed fan within 48 hours.
• You have replaced a hot-swap drive within 2 minutes of removal.
• You do not operate the server without the air baffles installed. Operating the server without the air baffles
might cause the microprocessor to overheat.
Notes: 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.

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:
• 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.
