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

You should extend only one component at a time - extending two or more

•
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

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
