[cisco-voip] Power problem

[Ahmed Elnagar]

Dear all
 
I have a 3560 switch connected to almost 14 7940 IP Phone, I have a very high call volume as it is an IPCC and a very loaded system
 
Sometime I have a very stange problem, all calls with outside callers do down on all IP Phones with no apperanet reason, sometime not all the phones it is a part of it only, sometime just only one phone.
 
I noticed this message in the logging of the switch also
 
2d09h: %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Fa0/8:ower Controller reports power Imax error detected2d09h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/8, changestate to down2d09h: %LINK-3-UPDOWN: Interface FastEthernet0/8, changed state to down2d09h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changestate to down2d09h: %ILPOWER-7-DETECT: Interface Fa0/8: Power Device detected: Cisco PD2d09h: %ILPOWER-5-POWER_GRANTED: Interface Fa0/8: Power granted2d09h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changestate to up
 
 
 
I have 12.2(25)SEE2 software version 
 
any ideas?
