Rack Mounting the Switch, Rack Mounting Safety Considerations

Page 20 highlights

Rack Mounting the Switch You may either place the switch on the rack shelf or mount the switch directly into a 19" wide, EIA-310-E- compliant rack (four-post, two-post, or threaded methods). The Dell ReadyRails™ system is provided for 1U front-rack, and two-post installations. The ReadyRails system includes two separately packaged rail assemblies and two rails that are shipped attached to the sides of the switch. WARNING: This 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. Rack Mounting Safety Considerations • Rack loading-Overloading or uneven loading of racks may result in shelf or rack failure, causing damage to the equipment and possible personal injury. Stabilize racks in a permanent location before loading begins. Mount the 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 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 40°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 the supply connections other than the direct connections to the branch circuit, for example: use of power strips. • Do not mount the equipment with the rear panel facing in the downward position. 14 Installation

Rack Mounting the Switch
You may either place the switch on the rack shelf or mount the switch directly
into a 19" wide, EIA-310-E- compliant rack (four-post, two-post, or threaded
methods). The Dell ReadyRails™ system is provided for 1U front-rack, and
two-post installations. The ReadyRails system includes two separately
packaged rail assemblies and two rails that are shipped attached to the sides
of the switch.
WARNING:
This 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.
Rack Mounting Safety Considerations
Rack loading—Overloading or uneven loading of racks may result in shelf
or rack failure, causing damage to the equipment and possible personal
injury. Stabilize racks in a permanent location before loading begins.
Mount the 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 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 40
°
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 the supply connections other than
the direct connections to the branch circuit, for example: use of power
strips.
Do not mount the equipment with the rear panel facing in the downward
position.
