Power should always be disconnected from the system when removing or in-•
stalling main system components, such as the motherboard, memory modules,
DVD-ROM and oppy drives (not necessary for hot-swappable drives). When
disconnecting power, rst 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 specically 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 on-board •
battery is installed upside down, which will reverse its polarities This battery
must be replaced only with the same or an equivalent type recommended by
the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
Please handle used batteries carefully. Do not damage the battery in any way; •
a damaged battery may release hazardous materials into the environment. Do
not discard a used battery in the garbage or a public landll. Please comply
with the regulations set up by your local hazardous waste management agency
to dispose of your used battery properly.
DVD-ROM laser: CAUTION - This server may have come equipped with a •
DVD-ROM drive. To prevent direct exposure to the laser beam and hazardous
radiation exposure, do not open the enclosure or use the unit in any uncon-
ventional way.
