Disclaimer: The Cisco Power Calculator is intended to be an educational resource and a starting point in
planning your power requirement; it is not a final recommendation from Cisco. This tool does not check for software
compatibility. To determine the power requirements and software most appropriate for your company we suggest you work
with a Cisco representative, Cisco channel partner or a solutions provider.

NOTE :
The Catalyst 4500 1300W and 4200W power supplies allocate variable amount of power to the system.Unlike the 2800W power supply which has
1400W for data and 1400W for PoE.The 1300W and 4200W, do not allocate a fixed amount of power for data and PoE.
PWR-C45-1400DC-P supply should be used in conjunction with an AC powered DC UPS . For more information, click&nbsp;<a href=

NOTE :
Output Power is the amount of power delivered from the Power Supply to the Catalyst 4500-E. To figure Input Power, divide output power by .85
(typical efficiency of the power supplies).
NOTE :
Output Power and Heat Dissipation numbers computed by the Cisco Power Calculator are maximum values and can be used for facility power and
cooling capacity planning. These figures are not indicative of the actual power draw or heat dissipation. Typical power draw is about 20% lower than
the maximum value shown. Also note that most of power allocated for PoE devices is dissipated at the end points.
