2-4 Warnings and Cautions
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
simultaneously may cause the rack to become unstable.
• Slide/rail-mounted equipment is not to be used as a shelf or workspace.
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 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.
