v
Remove items from your shirt pocket, such as pens and pencils, that might fall
into the server as you lean over it.
v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,
into the server.
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 you work
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 part 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 you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
Returning a device or component
If you are instructed to return a device or component, follow the packaging
instructions provided with the replacement part. Use any packaging materials for
shipping that are supplied to you.
Opening the bezel media door
To open the media door, complete the following steps:
1. Read the safety information that begins on page vii and “Handling
static-sensitive devices.”
2. Unlock the left-side cover.
Note: You must unlock the left-side cover to open or remove the bezel. When
you lock the left-side cover, it locks both the cover and the bezel.
3. Check the status of the media door icon. If the icon on the side of the bezel is
in the unlocked position, open the bezel media door directly.
