cal outlet. If an electrical accident occurs, you can then quickly remove
power from the system.

Do not work alone when working with high voltage components.

Power should always be disconnected from the system when removing
or installing main system components, such as the motherboard, memory
modules and the DVD-ROM and floppy drives (not necessary for hot
swappable drives). When disconnecting power, you should first power down
the system with the operating system and then unplug the power cords
from all the power supply modules in the system.

When working around exposed electrical circuits, another person who is fa-
miliar with the power-off controls should be nearby to switch off the power,
if necessary.

Use only one hand when working with powered-on electrical equipment.
This is to avoid making a complete circuit, which will cause electrical shock.
Use extreme caution when using metal tools, which can easily damage any
electrical components or circuit boards they come into contact with.

Do not use mats designed to decrease electrostatic discharge as protection
from electrical shock. Instead, use rubber mats that have been specifically
designed as electrical insulators.

The power supply power cord must include a grounding plug and must be
plugged into grounded electrical outlets.

Motherboard Battery: CAUTION - There is a danger of explosion if the
onboard battery is installed upside down, which will reverse its polarities

recommended by the manufacturer. Dispose of used batteries according to
the manufacturer’s instructions.

DVD-ROM Laser: CAUTION - this server may have come equipped with a
DVD-ROM drive. To prevent direct exposure to the laser beam and hazard-
