Rack or cabinet hardware installation
You may either place the switch on a rack shelf or mount the switch directly into a 19" wide, EIA-310- E-compliant rack. Rack
mounting includes four-post, two-post, or threaded mounts. The ReadyRails system is provided for 1U front-rack and two-post
installations.
The ReadyRails system includes separately packaged rail assemblies.
CAUTION:
Your switch is not NEBS Earthquake Z4-compliant if you use the 1U tool-less square-hole or two-post
installation methods.
WARNING:
This document is a condensed reference. Read the safety instructions in your
Safety, Environmental,
and Regulatory
information booklet before you begin.
NOTE:
The illustrations in this document are not intended to represent a specific switch.
NOTE:
Do not the use the mounted ReadyRails as a shelf or a workplace.
Rack mount safety considerations
●
Rack loading—Overloading or uneven loading of racks may result in shelf or rack failure, possibly damaging the equipment
and causing personal injury. Stabilize racks in a permanent location before loading begins. Mount the components starting at
the bottom of the rack, then work to the top. Do not exceed your rack’s load rating.
●
Power considerations—Connect only to the power source specified on the unit. When you install multiple electrical
components in a rack, ensure that the total component power ratings do not exceed the 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 the room ambient temperature. Use care not to exceed the 45°C (113°F) 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 the supply connections
other than the direct connections to the branch circuit, for example, use of power strips.
