Cleaning and Working with Internal Devices

WARNING

Do not disassemble, repair, or alter the server.

Never attempt to disassemble, repair, or alter the server on any occasion other than described in this manual. Failure to follow this instruction may cause an

electric shock or fire as well as malfunctions of the server.

Do not look into the CD-ROM drive.

A laser beam used in the CD-ROM drive is harmful to the eyes. Do not look into or insert a mirror into the drive while the drive is powered. If a laser beam is caught in your eyes, you may lose your eyesight (the laser beam is invisible).

Do not remove the lithium battery.

Your server contains the lithium battery. Do not remove the battery. Danger of explosion if the battery is incorrectly replaced. Placing the lithium close to a fire or in the water may cause an explosion.

When the server does not operate appropriately due to the dead lithium battery, contact your service representative to replace only with the same or equivalent type recommended by NEC. Do not disassemble the server to replace or recharge the battery by yourself.

Disconnect all the power plugs before accessing inside the server, or connecting the peripherals.

The server has two power cords.

Make sure to power off the server and disconnect the all power plugs from a power outlet before cleaning or installing/removing internal optional devices. Touching any internal device of the server with its power cords connected to a power source may cause an electric shock even of the server is off-powered.

Disconnect all the power plugs from the outlet occasionally and clean the plug with a dry cloth. Heat will be generated if condensation is formed on a dusty plug, which may cause a fire.
