Power Connection Guidelines for AC-Powered Systems
This section provides guidelines for connecting the Catalyst 4500 series switch
AC power supplies to the site power source. Basic guidelines include the
following:
• Make sure each chassis power supply has its own dedicated branch circuit.
• Size the circuits according to local and national codes.
• If you are using a 200/240 VAC power source in North America, use a
two-pole circuit breaker to protect the circuit.
• Place the source AC outlet within 6 feet (1.8 meters) of the system and make
sure it is easily accessible.
• Make sure the AC power receptacles used to plug in the chassis are the
grounding type. The grounding conductors that connect to the receptacles
should connect to protective earth ground at the service equipment.
Four types of AC-input power supplies are available:
• 1000 W—Table 2-1 lists the AC-input power cord options, specifications,
Cisco part numbers, and shows the different styles of 1000 W AC-input
power cord wall plugs that are available for North America and international
locations as well as the appliance coupler that is attached to the power supply
end of the power cord.
• 1300 W—Table 2-1 lists the AC-input power cord options, specifications,
and Cisco product numbers, and shows the different styles of 1300 W
AC-input power cord wall plugs that are available for North America or
various international locations as well as the appliance coupler that is
attached to the power supply end of the power cord.
Note For North America, the power cord plug types and appliance couplers
on the power supplies are different for the 1000 W power supplies and
the 1300 W power supplies; for other countries, the plugs shown are
the same for the 1000 W and 1300 W power supplies.
