Figure 12. Remove tool-less feature
3. Pull on the tool-less features to remove them from the rack rails.
4. Mount the rack rails directly to the front and back of the rack using two screws and clip nuts at the four mounting points.
5. Attach the inner switch rails to the switch.
Line up the rail with the mounting heads and attach the rail to the switch. For more information, see2RU front-rack
installation.
6. Align the switch rails with the rack rails and slide the switch into the rack until it is flush with the front of the rack.
7. Tighten the screws on the rails to secure the switch in the rack, if needed.
To install the switch in a rack you do not intend to ship, see Four-post rack mount.

Rack mounting safety considerations
NOTE:
To prevent bodily injury when mounting or servicing this unit in a rack, take special precautions to ensure that the
system remains stable. The following guidelines are provided to ensure your safety:
If your chassis is the only unit in the rack, mount it at the bottom of the rack.
When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component
at the bottom of the rack.
If the rack comes with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
If the chassis ships with blanks, remove the blanks from each slot before lifting the chassis.
NOTE: These instructions are 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 loadingOverloading 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 the load rating for your rack.
Power considerationsConnect 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 cables present fire and shock hazards.
Elevated ambient temperatureIf you install the switch 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 airflowDo not compromise the amount of airflow that is required for safe operation of the equipment. Install the
equipment in the rack so that the equipment constantly has the correct amount of airflow surrounding it.
Reliable earthingMaintain 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 fan panel facing in the downward position.
