Hi Team,

Am facing an issue with Cisco 7921 IP phone when connecting to third party PoE switch ( Extreme ), the issue is phone is not even powering up.

Can anyone help me with the solution or the reason

Please note that the Phone boots normally when connecting to Cisco switches ( C3960) .

With Thanks & Regards,

Pradeep.
