Rack Mounting Considerations
007-5467-001 2-17
Server Precautions
• Review the electrical and general safety precautions in Appendix E, “System Safety.”
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest server components in the bottom of the rack first, and then work up.
• Use a regulating uninterruptible power supply (UPS) to protect the server from power surges
and voltage spikes and to keep your system operating in case of a power failure.
• Allow the hot plug SATA drives and power supply modules to cool before touching them.
• Always keep the rack’s front door and all panels and components on the servers closed when
not servicing to maintain proper cooling.
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack
environment may be greater than the ambient temperature of the room. Therefore, consideration
should be given to installing the equipment in an environment compatible with the manufacturer’s
maximum rated ambient temperature (
35º C or 95º F)
. Refer to Appendix D, “System
Specifications” for information.
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required for safe operation
is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not arise due to
uneven mechanical loading.
