oh yea I also have this error &quot;port failed Power On Self Test.&quot;

Thanks. &nbsp;I was hoping I would not have to buy another one. &nbsp;Aww well. &nbsp;No there were no outside lines connected. &nbsp;And we did have a electrician come and and there were some issues with inconsistent power coming in. &nbsp;So the City has to come it to check that out as well.<br />
<br />
Thanks for you help.

Hi,<br />
<br />
There was lightning storm here the other day and the transformer infront of the office was hit. We lost power however there was a big bang and then nothing went to backup everything instantly shut off. <br />
Anyway I majority of the equipment is fine. &nbsp;The only wierd thing this is we have a 3com 3250 with to ports that show up red in the web interface. &nbsp;But I think those 2 are blocking other from working fine. &nbsp;Is there a way to reset inidvidual ports on these switches? &nbsp;I have rebooted these several time. &nbsp;but with no luck.<br />
<br />
Thanks in advance.

3Com Switch ports not responding

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
