Rack Mounting Considerations
007-5839-001 11
Server Precautions
• Review the electrical and general safety precautions.
• 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.
• Add 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-pluggable disk drives and power supply modules to cool before touching.
• Always keep the rack’s front door and all panels and components on the servers closed when
not servicing to maintain proper cooling.
• The server is not considered suitable for visual display work place devices under the German
government ordinance for work with visual display units.
Rack Mounting Considerations
Use the guidelines provided in the following subsections to properly install the server in a rack.
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)
.
Important: In a system using three NVIDIA M2090 GPUs the maximum rated ambient
temperature of the operational environment should be 30
º C (86º F).
A system using two M2090
GPUs in the front slot positions can be operated at 35º C (95º F) with 115 watt system CPUs.
Check with your SGI sales or service representative for additional information on this topic.
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required for safe operation
is not compromised.
