Rack Precautions
•
Ensure that the leveling jacks on the bottom of the rack are extended to the
floor so that the full weight of the rack rests on them.
•
In single rack installations, 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 server or other com-
ponent from the rack.
•
You should extend only one server or component at a time - extending two or
more simultaneously may cause the rack to become unstable.
Server Precautions
•
Review the electrical and general safety precautions in Chapter 3.
•
Determine the placement of each component in the rack before you install the
rails.
•
Install the heaviest server components at the bottom of the rack first and then
work your way up.
•
Use a regulating uninterruptible power supply (UPS) to protect the server from
power surges and voltage spikes and to keep your system operating in case
of a power failure.
•
Allow any drives and power supply modules to cool before touching them.
•
When not servicing, always keep the front door of the rack and all covers/panels
on the servers closed to maintain proper cooling.
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating
temperature of the rack environment may be greater than the room's ambient
temperature. Therefore, consideration should be given to installing the equipment
in an environment compatible with the manufacturer’s maximum rated ambient
temperature (Tmra).
