S5148F-ON switch installation
To install the S5148F-ON switch, complete the installation procedures in the order presented in this section.
Always handle the switch and components with care. Avoid dropping the switch or its field replaceable units (FRUs).
NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap
when handling the S5148F-ON switch and components. As with all electrical devices of this type, take all the necessary
safety precautions to prevent injury when installing this switch.

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.
