Can the 7941 phones power requirements be staticly changed to below the 12.9 W that it auto negitiates? 3560 switch allows for only 26 devices, can you adjust the power settings to be able to connect more phones.

Hi
Do you mean the 7941g-ge or just the 7941?
If it's the 7941 then something seems wrong as it's supposed to be a Class 2 device...
If you mean the GE one, it's probably already negotiated the minimum power it needs as it's a Class 3 device and is negotiating less than 15.4w...

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.
