components beginning at the bottom of the rack, then work to the top. Do
not exceed your rack load rating.
•
Power considerations: Connect only to the power source specified on the
unit. When multiple electrical components are installed in a rack, ensure
that the total component power ratings do not exceed circuit capabilities.
Overloaded power sources and extension cords present fire and shock
hazards.
•
Elevated ambient temperature: If installed in a closed rack assembly, the
operating temperature of the rack environment may be greater than room
ambient. Use care not to exceed the 50°C maximum ambient temperature
of the switch.
•
Reduced air flow: Install the equipment in the rack so that the amount of
airflow required for safe operation of the equipment is not compromised.
•
Reliable earthing: Maintain reliable earthing of rack-mounted equipment.
Pay particular attention to supply connections other than direct
connections to the branch circuit (for example, use of power strips).
•
Product should not be mounted with the rear panel facing in the downward
position.
Installing the Dell ReadyRails System
The ReadyRails system is provided to easily configure your rack for installation
of your switch. The ReadyRails system can be installed using the 1U tool-less
method or one of three possible 1U tooled methods (two-post flush mount, two-
post center mount, or four-post threaded).
