Im having a problem with the 48-port Gigabit ethernet blade (48-port 10/100/1000BaseT (RJ45)) on a 4506 switch, one of the ports only support 100Mb, if hardcoded to 1000Mb on both sides, then the connectivity would be gone. All other ports on this blade seem fine.
Would it be a hardware issue? Any idea what caused it?
As you have mentioned that when u r hard coding the port into 1000 Mbps ur connectivity is gone so in my opinion you just check the cabling. If possible re punch the cable into the patch panel and replace the patch cord and hope it will work fine afterwards. If this does not work out contact the equipement vendor and get it replaced if its in Warranty.
as mension in your post ...all other ports work fine then first of all check it out the cable by plug in into the other porst...if the cable is not good then replace it...and then if u find calbe is perfect then there may be chances that your port of switch not working properly...
Thanks for your suggestions.. I actually tested many good cables directly on my laptop. what I found was that with the same cable and same setting on the server NIC, it works perfect on 1000 on any other port of the same blade. It did appear to me as a hardware or internal wiring issue, but without being able to trace down where exactly the problem is, Im just a bit concerned that if a blade swap would be the fix. As this is a quite important switch to us, is there a non-intrusive way to find out?
Any diagnostics, with or without testing equipment, are going to require disconnecting either or both ends of the cable.
You can follow the cable through the system and inspect all of the connections (patch cable->panel->info outlet->patch cable to the host), maybe try re-punching the connection at the panel to make sure the wires are seated into the IDC connector.
You'd be looking primarily at the blue and brown pairs (green and orange are used for Ethernet/Fast Ethernet).
Likely as not, one of the blue or brown pair are reversed (i.e., white-blue and blue are swapped at the panel).
If that's the case, you'll need to clear and re-punch the pair.
