Installing the switch | 28
n If your installation requires a different power cord than the one supplied with the switch and power supply,
be sure that the cord is adequately sized for the current switch 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.
n Do not ship any switch in a rack without checking for restrictions. Otherwise, you may void the switch
warranty.
n 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.
n When installing the switch, ensure that the AC outlet is near the switch. Make it easily accessible in case
the switch must be powered off.
n 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. For operating temperature information, see Physical and environmental specifications.
n Ensure that the switch does not overload the power circuits, wiring, and over-current protection at your
installation site. 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 are printed on the devices near the AC power connectors.
n Avoid blocking any ventilation openings on the sides, rear, or front of the switch.
n Ensure that the air flow around the switch is not restricted. Leave at least 3 inches (7.6 cm) for cooling.
n A slot cover plate MUST be secured over any power supply slot that does not contain a power supply unit.
This is required for proper air flow and thermal operation. Leaving a power supply slot uncovered can
cause an over-temperature condition inside the switch that can result in the switch shutting down. During
replacement of a power supply unity, it is acceptable to allow the slot to remain uncovered for up to two
minutes in a switch connected to a power source.
n Marking label (includes power rating) is at the bottom of the switch.
n This switch equipment is not suitable for use in locations where children are likely to be present.
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 a cover plate on any slot in the switch that is not in use.
Prepare the installation site
Cabling Infrastructure: Ensure the cabling infrastructure meets the necessary network specifications. See Cabling
and Technology Information for more information.
Installation Location: Before installing the switch, plan its location and orientation relative to other devices and
equipment:
n In the front or the back of the switch, leave at least 7.6 cm (3 inches) of space for the twisted-pair and fiber-optic
cabling.
n In the back of the switch, leave at least 7.6 cm (3 inches) of space for the power cord.
n On the sides of the switch, leave at least 7.6 cm (3 inches) for cooling, except if the switch is installed in an open
EIA/TIA rack.
