2 The information is based on the rating of the power supply (max.) and does not reflect the actual measured consumption numbers. For the actual power consumption based on measurement, see the data sheet at: http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps12995/data_sheet_c78-728232.html
3 The total input and total output BTU ratings refer to input power to the power supply and output power to the switch. The BTU ratings are based on 100 VAC for the 250-W and 640-W power supplies and 115 VAC for the 1025-W power supply .
