Installation Precautions and Guidelines

To help avoid personal injury or product damage when installing your switch, read the following installation
precautions and guidelines.
CAUTION
n
Do not mount the switch on a wall, under a table, or under any other horizontal surface.
n
Mount devices installed in a rack or cabinet as low as possible. Put the heaviest devices at the bottom and
n
progressively lighter devices positioned higher.
To prevent the rack or cabinet from becoming unstable and/or falling over, ensure that it is adequately secured.
n
The switch may use more than one power supply cable. To fully power down the switch, you must disconnect all
n
power supply cables from the switch.
WARNING
n
Do not ship any switch in a rack without checking for restrictions in the latest Aruba Installation and Getting
n
Started Guide. Otherwise, you may void the switch warranty.
Ensure the power source circuits are properly grounded, then connect the switch to the power source by using
n
the power cord supplied with the switch. For more information on power cords, see
When installing the switch, the AC outlet should be near the switch and be easily accessible in case the switch
n
must be powered off.
Ensure that the power cord and network cables at the switch mounting location do not create a tripping hazard.
n
Do not install the switch in an environment where the operating ambient temperature exceeds its specification.
n
See the environmental operating temperature information in the
section of this guide.
Ensure that the switch does not overload the power circuits, wiring, and over-current protection. To determine
n
the possibility of overloading the supply circuits, add the ampere ratings of all devices installed on the same
circuit as the switch. Then compare the total with the rating limit for the circuit. The maximum ampere ratings
for a device are usually printed near the device AC power connectors.
Do not block any ventilation openings on the front or rear of the switch.
n
Leave a minimum of 6 inches (15.24 cm) for cooling at the front and back of the switch. For the air flow direction,
n
see the Fan Trays on page 16
If a power supply or fan tray must be removed and reinstalled, wait at least 5 seconds before reinstallation.
n
Otherwise, damage to the switch may occur. The power supply needs this time to discharge any retained power.
