I have the setup of 8, 3750G-24ps switches, in a stack(using stack cable). IOS 12.2(44)se1(c3750-advipservicesk9-mz.122-44.SE1.bin), is installed in all switches. Nortel class 3 IP phones are connected to all the ports which required 15.4 watt powar. If i am unplugging any ip phone from any port of the switch and replugging the same back to that port the switvh port does not comes up. but if i am restarting the switch all the port works fine with the same IP phones.
when the error occures I am getting the following error message after exactly 15 seconds" Jul 31 19:28:11: %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interfac
e Gi1/0/12: Power given, but Power Controller does not report Power Good ".
Also #sh power inline shows the below status for the 12 port :
Gi1/0/12 auto faulty 0.0 n/a n/a 15.4
appart from the above port more 3 ports are also not working similarly, which were generating the same syslog message and now showing operational status OFF.
as shown bellow.
Interface Admin Oper Power Device Class Max
Gi1/0/15 auto off 0.0 n/a n/a 15.4
Gi1/0/16 auto off 0.0 n/a n/a 15.4
Kindly help me to resolve the issue.
