Rack Precautions
•Ensure that the leveling jacks on the bottom of the rack are fully extended to the fl oor with the full weight of the rack resting on them.
•In single rack installation, stabilizers should be attached to the rack.
•In multiple rack installations, the racks should be coupled together.
•Always make sure the rack is stable before extending a component from the rack.
•You should extend only one component at a time - extending two or more simul- taneously may cause the rack to become unstable.
Server Precautions
•Review the electrical and general safety precautions in Chapter 4.
•Determine the placement of each component in the rack before you install the rails.
•Install the heaviest server components on the bottom of the rack fi rst, and
then work up.
•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 hot plug SAS drives and power supply units 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.
