Safety Precautions

ATTENTION:

Before changing your system configuration, always back up your data to prevent data loss.

Hardware should only be handled by qualified technicians in an ESD safe environment with ESD safe tools.

Before installing components, always consult the manufacturer’s manual.

CAUTION:

Always turn off the power to your system and remove the AC power cord before installing or removing hardware to avoid experiencing electrical shock or damaging the system.

During operation, heat sinks can heat up significantly. Do not touch them immediately after turning off the power. Leave sufficient time for cooling off before touching them to avoid burns.

Server systems require sufficient ventilation, as provided by a rack case. Insufficient ventilation can cause overheating of components and potentially damage them.
