PoE b7450 Problem

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:

 

#show run int ethernet 1/1/27

hello,

follow these steps to eliminate that error

Verify that the powered device works on different ports and that the hassle is handiest on one port.

Step 2 Use the display run and show interface repute privileged EXEC commands to verify that the port isn't always shut down. (maximum Cisco switches flip off port energy whilst the port shuts down.)

Step 3 Use the display interface repute privileged EXEC command to confirm that the switch port is not blunders disabled.

Step 4 Use the display run and show electricity inline interface-identity privileged EXEC command to confirm that the strength inline in no way interface configuration command isn't configured on the port.

Step five affirm that the Ethernet cable from the smartphone to the transfer port is right. connect a recognised excellent non-PoE Ethernet tool to the Ethernet cable, and ensure that it establishes a hyperlink and exchanges site visitors with any other host.

Step 6 verify that the entire cable length from the switch the front panel to the connected tool (powered tool) isn't more than 100 meters. For more information, see the cable diagnostics phase in the switch software program configuration guide.

Step 7 Disconnect the Ethernet cable from the transfer port. Use a short Ethernet cable to attach a regarded proper Ethernet tool to this transfer port (no longer at a patch panel). confirm that the device establishes an Ethernet link and exchanges visitors with every other host, or ping the port VLAN SVI. subsequent, connect a powered tool to this port, and verify that it powers on. If it does no longer energy on, go to Step 8.

Step eight Use the display inline electricity and show inline power detail privileged EXEC instructions to examine the number of linked powered gadgets towards the transfer electricity budget (to be had PoE). verify that switch strength finances can electricity the device
