4: System Safety
NAS Node Serverboard Battery
Caution: There is a danger of explosion if an onboard battery is installed upside down, which
will reverse its polarities (see Figure 4-1). This battery must be replaced only with the same
or an equivalent type recommended by the manufacturer. Check with your service
representative if you have any questions. Dispose of used batteries according to the
manufacturer's instructions.

Mainboard Replaceable Soldered-in Fuses
Important: If your system comes with self-resetting PTC (Positive Temperature Coefficient)
fuses on the NAS head node serverboard, they must be replaced by trained service technicians
only. The new fuse must be the same or equivalent as the one replaced. Contact your technical
support organization for details and support.
General Safety Precautions
Follow these rules to ensure general safety:
• Keep the area around the system clean and free of clutter.
• 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.
