The server supports 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 the server with the power on:
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. These items
might fall into the server as you lean over it.
v Avoid dropping any metallic objects into the server, such as paper clips,
hairpins, and screws.
Handling static-sensitive devices
Attention
Do not open the static-protective package containing the new part until the defective part
has been removed from the server and you are ready to install the new part. Static
electricity, although harmless to you, can seriously damage server components and parts.
When you handle server parts and components, take these precautions to avoid
static-electricity damage:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Wear an electrostatic-discharge wrist strap, if one is available.
v Always carefully handle the parts and other components (such as PCI cards,
memory modules, system boards, and microprocessors) by its edges or its frame.
Do not touch solder joints, pins, or exposed circuitry.
v Prevent others from touching the parts and other computer components.
v Before you replace a new part, touch the static-protective package containing the
new part to a metal expansion-slot cover or other unpainted metal surface on
the server for at least two seconds. This reduces static electricity from the
package and your body.
v Remove the new part from the static-protective package and directly install it in
the server without placing it on any other surface. If it is hard for you to do this
in your specific situation, place the static-protective package of the new part on
a smooth, level surface, and then place the new part on the static-protective
package.
v Do not place the part on the server cover or other metal surface.
v Take additional care when handling devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
