<p class="MsoNormal">Having an issue related to PoE negotiation between 3650 switches that we are beginning to deploy and older cisco phones such as 7960s and 7940s . I think these are using the pre PoE standard. Symptoms are when the stack reloads the switchports
connected to Cisco 7960 telephones come up in a hung state:<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">7960 Telephones showed no power<o:p></o:p></p>
<p class="MsoNormal">No link lights on switchport<o:p></o:p></p>
<p class="MsoNormal">Switchport status showed UP/UP <o:p></o:p></p>
<p class="MsoNormal">Switchport remained in UP/UP state even after disconnecting the cable from switchport<o:p></o:p></p>
<p class="MsoNormal">Shut/no shut port and the telephone would reboot normally<o:p></o:p></p>
<p class="MsoNormal">Moving to available switchport and telephone rebooted normally<o:p></o:p></p>
<p class="MsoNormal">Bypassed telephone and connected PC and the PC would reboot normally reconnected telephone and the telephone would reboot normally.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Newer phones such as 7942 come right up.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Once we performed a shut/no shut on all switch ports and all telephones recovered normally but still this is not normal behavior. Going to open a TAC case but wondering if anyone else has experienced this?<o:p></o:p></p>
<p class="MsoNormal">Switches are WS-C3650-48PD on Version 03.03.05SE.<o:p></o:p></p>
