The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

How to Enable Power Inline on Cisco 3500 seriesXL for Mitel VOIP handset to operate cascading off the Mitel Appliance?

Asked by westonp in Telecommunications, Network Switches & Hubs, IP Telephony

Tags: Cisco Power inline, Mitel VOIP, Cisco POE, Cisco VOIP

I have an working Mitel 3300cxi 12-port POE Switch Appliance that has all 12 ports connected to Mitel 5235 & 5340 handsets. The users computers plug into a lan port on each handset. I have the need to expand the number of POE ports in the server room for additional handsets by cascading the connection from the Mitel appliance to a Cisco Catalyst 3500 Series XL. The expected result will allow me to plug in POE handsets into the Cisco to get power and data similarly as one would cascade a plain'ol switch.

The process I'm using is
1) configure terminal
2) interface FastEthernet 0/2   ***Note: I'm testing 0/2 with a Mitel handset plugged into 0/2***
3) power inline auto <cr>
4) ctrl-Z to end

Afterwards, I check status by:
1) show power inline FastEthernet 0/2  ***Note: the result is not what I expect which is:
Interface=FastEthernet Phone=Unknown Power=no

Note: This phone powers up and communicates fine if directly on the 12-port Mitel 3300 CXI appliance
the question is, what am I missing to get the phone operational on the Cisco switch?
