before touching them.
WARNING: WARNING:
To reduce the risk of personal injury, electric shock, or damage to the equipment, remove the power cord to remove
power from the server. The front panel Power On/Standby button does not completely shut off system power. Portions
of the power supply and some internal circuitry remain active until AC/DC power is removed.
WARNING: WARNING:
To reduce the risk of fire or burns after removing the energy pack:
Do not disassemble, crush, or puncture the energy pack.
Do not short external contacts.
Do not dispose of the energy pack in fire or water.
Do not expose the energy pack to low air pressure as it might lead to explosion or leakage of flammable liquid or
gas.
Do not expose the energy pack to temperatures higher than 60°C (140°F).
After power is disconnected, battery voltage might still be present for 1s to 160s.
CAUTION: CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating uninterruptible power
supply. This device protects the hardware from damage caused by power surges and voltage spikes and keeps the
system in operation during a power failure.
CAUTION: CAUTION:
Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner
results in improper airflow and improper cooling that can lead to thermal damage.
