WARNING: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type
recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.
CAUTION: The power supplies are hot-pluggable. The system requires two power supplies to be installed for the system to operate normally.
The system is in the redundant mode when all three power supplies are installed. Remove and replace only one power supply at a time.
NOTE: There are two fan assemblies containing two individual fans. One assembly is located near the SCSI backplane board. The other fan assembly is
attached to the back-panel.
CAUTION: The cooling fans are hot-pluggable. To maintain proper cooling while the system is on, only replace one fan at a time.
