dead network port: Server or switch?

Albator — Thu, 31 Mar 2011 12:45:03 GMT

Hello everyone!

one of our half-height BL460c G1 server lost connection on one network port. How can I tell if it is the NIC port or the switch port? I have no slots left to move the server to another slot. The switch shows the port as down/down.

Thank you!

Hi,

What Interconnect are you using in the back of your enclosure?
i.e. Cisco 3020, SAS switch, ProCurve switch, GbE2c switch?
Or is it a Pass-Thru module going to an external switch?

Hi,

because, as you likely know, the connections between the blades I/O and the interconnects (like the Cisco switches i.e.) in the back are hardwired by design, the only way i see that you can determine 100% if this is a server LAN port issue or a LAN switch issue is swap 2 blade servers from position....
This impacts both servers but if you already removed/reseated the blade itself and this issue stays then the next step with the least impact is changing this blade to another slot.

I don't know if the Cisco switch allows to disable/re-enable a port, to see if this 'wakes' up the connection....
