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.
General Server Precautions
- Review the electrical and general safety precautions that came with the compo-
nents you are adding to your chassis.
- 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 hard drives and power supply modules to cool before touch-
ing 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 multi-unit rack assembly, the ambient operating tempera-
ture of the rack environment may be greater than the ambient temperature of the
room. Therefore, consideration should be given to installing the equipment in an
environment compatible with the manufacturer’s maximum rated ambient tempera-
ture (Tmra).
