Safety Information and Technical
Specifications
Be aware of the locations of the power on/off switch on the chassis as well as
the room's emergency power-off switch, disconnection switch or electrical
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 server board, memory
modules and the DVD-ROM and floppy drives (not necessary for SATA
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
familiar 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 unconventional way.
Server board replaceable soldered-in fuses: Self-resetting PTC (Positive
Temperature Coefficient) fuses on the server board must be replaced by
trained service technicians only. The new fuse must be the same or equivalent
as the one replaced. Contact technical support for details and support.
