2-4 Warnings and Precautions
Rack Precautions
•
Ensure that the leveling jacks on the bottom of the rack are fully extended to
the floor 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 si-
multaneously 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 first, 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 any hot plug 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.
