2: Server Installation
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: Certain system configurations using higher-wattage processors and PCIe option
cards may require the maximum rated ambient temperature of the operational environment be 30º
C (86º F) or lower. Altitude of operation can also affect required ambient air temperatures, see
Table B-1 on page 61 . Check with your SGI sales or service representative for additional
information on this topic.
