Aaron is totally right, although the 7941G is a Class 2 IEEE device, it does not require a continuous draw of 6.49W (standard Class 2)
When Cisco IP phones are connected to common switches such as the Catalyst 3560 or Catalyst 3570, the switch can automatically detect the phone type and provide the exact amount of power that the phone needs. The use of Cisco Discovery Protocol provides this greater granularity to the power classification, allowing for more accurate reporting of power consumption. This means that Cisco phones can be more energy-efficient than other IP phones in the same IEEE power class, allowing for more IEEE endpoints per switch or a lower overall power budget.
The 7941G-GE is a Class 3 IEEE device, so the switch provides the minimum power it needs.
