Japan Power Cord Warning
Installation precautions
Follow these precautions when installing the switch.
WARNING:
• The rack or cabinet should be adequately secured to prevent it from becoming unstable and/or
falling over.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 installed above.
• When wall mounting, to meet national and international safety requirements, wall mount with the
network ports facing up. The side vents cannot be placed up or downward.
CAUTION:
• When installing the switch, the AC outlet should be located near the switch and should be easily
accessible in case the switch must be powered off.
• Ensure that the AC power source circuits are properly grounded.
• Use only the AC/DC power adapter and power cord (if applicable), supplied with the switch. Use
of other adapters or power cords, including those that came with other Hewlett Packard
Enterprise Networking products, may result in damage to the equipment. For those switches that
use a power cord, if your installation requires a different power cord than the one supplied with
the switch, be sure to use a power cord displaying the mark of the safety agency that defines the
regulations for power cords in your country. The mark is your assurance that the power cord can
be used safely with the switch.
• 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 might
exceed 40°C (104°F). This includes a fully-enclosed rack. Ensure the air flow around the sides
and back of the switch is not restricted. Leave at least 7.6 cm (3 inches) for cooling.
• Ensure all port covers are installed when the port is not in use.
