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 could 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 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.

Major components of the server

Blue on a component indicates touch points, where you can grip the component to

remove it from or install it in the server, open or close a latch, and so on.

Orange on a component or an orange label on or near a component indicates that

the component can be hot-swapped, which means that if the server and operating

system support hot-swap capability, you can remove or install the component while

the server is running. (Orange can also indicate touch points on hot-swap

components.) See the instructions for removing or installing a specific hot-swap

component for any additional procedures that you might have to perform before you

remove or install the component.
