Safety Precautions
To avoid personal injury or product damage when installing your switch, read the installation precautions and guidelines below.
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.
Cautions
Ensure the power source circuits are properly grounded, then use the power cord supplied with the switch to connect
■
to the AC power source.
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 the air flow
■
direction, see the Installation and Getting Started Guide for your product, located on the HP Networking web site
at www.hp.com/networking/support.
For additional Safety and Regulatory information, refer to the Safety and Regulatory documentation included with your switch.
