The file module supports hot-plug, hot-add, and hot-swap devices and is designed
to operate safely while it is turned on and the cover is removed. Follow these
guidelines when you work inside a file module that is turned on:
v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved
shirts before working inside the file module; do not wear cuff links while you
are working inside the file module.
v Do not allow your necktie or scarf to hang inside the file module.
v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
v Remove items from your shirt pocket, such as pens and pencils, that could fall
into the file module as you lean over it.
v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,
into the file module.
Handling 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:
v Limit your movement. Movement can cause static electricity to build up around
you.
v 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
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v 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.
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, put 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. Heating
reduces indoor humidity and increases static electricity.
