Installation precautions and guidelines
To help avoid personal injury or product damage when installing your switch, read the following installation precautions
and guidelines.
This section provides precautions and guidelines to observe when installing your switch. For full installation instructions,
see the Aruba 2930M Switches Installation and Getting Started Guide at http://h17007.www1.hpe.com/us/en/
networking/library/index.aspx?cat=switches&subcat=2930M&type=7. (Scroll to the Installation section and select the
latest version of the above-mentioned guide.)
WARNING:
• Do not mount the switch on a wall or under a table or under another horizontal surface.
• Mount devices installed in a rack or cabinet as low as possible. Put the heaviest devices at the bottom
and progressively lighter devices positioned higher.
• To prevent the rack or cabinet from becoming unstable and/or falling over, ensure that it is adequately
secured.
CAUTION:
• Do not ship any switch in a rack without checking for shipping restrictions in the Installation and Getting
Started Guide for your switch. Otherwise, you may void the switch warranty.
• Ensure that the power source circuits are properly grounded. Then connect the switch to the power
source by using the power cord supplied with the switch. For more information on power cords, see
Power cords on page 3.
• When installing the switch, ensure that the AC outlet is near the switch and easily accessible in case the
switch must be powered off.
• Ensure that the power cord and network cables at the switch mounting location do not create a tripping
hazard.
• Do not install the switch in an environment where the operating ambient temperature exceeds its
specification. (See the environmental operating temperature information in the Installation and Getting
Started Guide for your switch product. Visit http://www.hpe.com/networking/ResourceFinder and
locate the installation guide by using the search tool on the resulting destination page. )
• Ensure that the switch does not overload the power circuits, wiring, and over-current protection. To
determine 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.
• Avoid blocking any ventilation openings on the sides, rear, or front of the switch.
• Ensure that the air flow around the switch is not restricted. Leave at least 3 inches (7.6 cm) for cooling.
For the air flow direction, see the Installation and Getting Started Guide for your product at http://
www.hpe.com/networking/ResourceFinder. (Locate the installation guide by using the search tool on
the resulting destination page.)
• If a power supply must be removed, and then reinstalled, wait at least 5 seconds before reinstallation.
Otherwise, damage to the switch may occur. The power supply needs this time to bleed off any retained
power.
• Install cover plates on any slot that is not in use.
