Subject: [cisco-voip] 3650 PoE Issue<o:p></o:p></span></p>
<div>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">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></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif""> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">7960 Telephones showed no power<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">No link lights on switchport<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Switchport status showed UP/UP
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Switchport remained in UP/UP state even after disconnecting the cable from switchport<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Shut/no shut port and the telephone would reboot normally<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Moving to available switchport and telephone rebooted normally<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Bypassed telephone and connected PC and the PC would reboot normally reconnected telephone and the telephone would reboot normally.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif""> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Newer phones such as 7942 come right up.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif""> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">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></span></p>
<p class="MsoNormal"><span style="font-family:"Calibri","sans-serif"">Switches are WS-C3650-48PD on Version 03.03.05SE.<o:p></o:p></span></p>
