Chapter 2: Server Installation
•Use a regulating uninterruptible power supply (UPS) to protect the server from power surges, voltage spikes and to keep your system operating in case of a power failure.
•
•
Allow the power supply units and hot plug Serial ATA drives 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
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.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply circuitry and the effect that any possible overloading of circuits might have on overcurrent protection and power supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself should be grounded. Particular attention should be given to power supply connec- tions other than the direct connections to the branch circuit (i.e. the use of power strips, etc.).
