Safety Precautions
To avoid personal injury or product damage when installing your switch, read the installation precautions and guidelines below.
For additional Safety and Regulatory information, refer to the Safety and Regulatory documentation included with your switch.
Installation Precautions
Warnings
■
The rack or cabinet should be adequately secured to prevent it from becoming unstable, tilting or falling.
Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest devices at the
bottom and progressively lighter devices above.
■
Do
not
wall-mount any switch without checking for restrictions in the
Installation and Getting Started
Guide
.
Wall-mount the switch with network ports facing up or down (away from or toward the floor). Do
not
wall-mount the switch with the ventilation or fan ducts facing up or down.
Cautions
■
If your installation requires a different power cord than the one supplied with the switch and/or power supply, be
sure the cord is adequately sized for the switch’s current requirements. In addition, be sure to use a power cord
displaying the mark of the safety agency that defines the regulations for power cords in your country/region. The
mark is your assurance that the power cord can be used safely with the switch and power supply.
■
When installing the switch, the AC outlet should be near the switch and should be easily accessible in case the switch
must be powered off.
■
Ensure the switch does not overload the power circuits, wiring, and over-current protection. To determine the
possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same
circuit as the switch and compare the total with the rating limit for the circuit. The maximum ampere ratings are
usually printed on the devices near the AC power connectors.
■
Do not install the switch in an environment where the operating ambient temperature exceeds its specification.
■
Ensure the air flow around the switch is not restricted. Leave at least 7.6 cm (3 inches) for cooling. For other available
air flow information, see the
