RMC 7189
1U Rackmount System
o Motherboard Battery: CAUTION - There is a danger of explosion if the onboard
battery is installed upside down, which will reverse its polarites (see Figure 4-1). 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.
o 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.
o Mainboard replaceable soldered-in fuses: Self-resetting PTC (Positive Tempera- ture Coefficient) fuses
on the mainboard 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.
4-2 General Safety Precautions
Follow these rules to ensure general safety:
o Keep the area around the RMC7185 clean and free of clutter.
o The RMC7189 weighs approximately 37 lbs (16.8 kg). When lifting the system, two people at either end
should lift slowly with their feet spread out to distribute the weight. Always keep your back straight and lift
with your legs.
o Place the chassis top cover and any system components that have been re- moved away from the sys-
tem or on a table so that they won't accidentally be stepped on.
o While working on the system, do not wear loose clothing such as neckties and unbuttoned shirt sleeves,
which can come into contact with electrical circuits or be pulled into a cooling fan.
o Remove any jewelry or metal objects from your body, which are excellent metal conductors that can
create short circuits and harm you if they come into contact with printed circuit boards or areas where
power is present.
