• Each of the drive bays has either a drive or a filler panel installed.
• Each of the power supply bays has either a power supply or a filler panel
installed.
• The cover is in place during normal operation.

• The cover is removed for no longer than 30 minutes while the server is operating.
• A removed hot-swap drive is replaced within two minutes of removal.
• Cables for optional adapters are routed according to the instructions provided
with the adapters.
• A failed fan is replaced within 48 hours.
Working inside a server with power on
Your server supports hot-plug, hot-add, and hot-swap devices and it is designedto
operate safely while turned on with the cover removed. Follow these guidelines when
you work inside a server that is turned on:
• Avoid 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.
• Do not allow your necktie to hang inside the server.
• Remove jewelry, such as bracelets, necklaces, and loose-fitting wrist watches.
• Remove items from your shirt pocket (such as pens or pencils) that could fall into
the server as you lean over it.
• Take care to avoid dropping any metallic objects, such as paper clips, hair pins, or
screws, into the server.
Handling static-sensitive devices
Static electricity, though harmless to you, can seriously damage server components or
options.
Note: When you are adding an internal option, do not open the static-protective
package containing the option until you are instructed to do so.
When you handle options and other server components, take these precautions to
avoid damage from static electricity:
• Limit your movement. Movement can cause static electricity to build up around
you.
• Always handle components carefully. Handle adapters, the memory board, and
memory modules (DIMMs) by the edges. Never touch any exposed circuitry.
• Prevent others from touching components.
• When you are installing a new option, touch the static-protective package
containing the option to a metal expansion-slot screw or other unpainted metal
surface on the server for at least two seconds. (This reduces static electricity from
the package and from your body.)
• When possible, remove the option and install it directly into the server without
setting the option down. When this is not possible, place the static-protective
package that the option comes in on a smooth, level surface and place the option
on it.
• Do not place the option on the server's covers or any metal surface.
