  • 1.  PoE b7450 Problem

    Posted May 12, 2018 05:04 AM

    Hello,

     

    We recently upgraded our infastructure from Cisco to Brocade devices. Im going to include a show version output but its a b7450 48port model. Earlier I recieved a complaint from a client regarding loss of internet connecvitity. After investigating the issue I realized that a Cisco 8841 phone was not powering up and since the phone wasnt powering up it wasnt sharing the network connecvitity. When  remove the phone from the equation the computer authenticates ( dot1x ) with no issues. The first thing I did was validate the power inline settings.

    After the power settings were checked I verified that the port was enabled and was functioning. I also bounched the port for good measure with the disable/enable command but that didnt seem to yield any results. What could possible be wrong with the device?  With so much power available to the switch why arent the VoIP phones getting power with the configuration settings are correct? My gut is telling me there may be something wrong with the switch's firmware so Ill go ahead and include the show version.

    Its also worth mentniong that I tested a few other ports and I was able to get one port working 1/1/27. The ports configuration is identical to other ports on the switch but this one seems to be one of the few ports actually providing power:
