SC809 Chassis Manual
2-2
Power should always be disconnected from the system when removing or install-
•
ing main system components, such as the serverboard, memory modules and
the DVD-ROM/USB comport unit. When disconnecting the 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.
Serverboard battery: CAUTION - There is a danger of explosion if the onboard
•
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.
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.
2-5 General Safety Precautions
Keep the area around the chassis clean and free of clutter.
•
Place the chassis top cover and any system components that have been re-
•
moved away from the system or on a table so that they won’t accidentally be
stepped on.
