v
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.
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 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.
Removing the cover and bezel
To remove the cover and bezel, complete the following steps:
1. Read the safety information that begins on page v and “Installation guidelines”
on page 28.
2. If you are installing or replacing a non-hot-swap component, turn off the server
and all attached peripheral devices. Disconnect all power cords; then,
disconnect all external signal cables from the server.
3. Slide the server out of the rack until the slide rails lock into place.
