Installation Precautions
WARNINGS ■ 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.
■ For safe operation do not install the switch with the side of the
switch (with the fan vents) facing either downward or upward.
Cautions ■ If one of the following switches is to be mounted in a rack, you can use a
rack kit, J9583A - HP X410 1U Universal 4-Post Rack Mounting Kit for the
following switches only:
• J9085A HP Switch E2620-24
• J9088A HP Switch E2620-48
• J9086A HP Switch E2620-24-PPoE+
■ Ensure the power source circuits are properly grounded, then use the
power cord supplied with the switch to connect it to the power source.
■ If your installation requires a different power cord than the one supplied
with the switch, ensure 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. The mark is your assurance that the power cord can be
used safely with the switch. If the PoE+ device’s supplied power cord does
not fit, contact HP networking support.
■ 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. 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 55°C (131°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.
