Modular Server CM MFS5000SI - Link has been disconnected

Hello,

i'm having trouble with a Intel Modular Server an Computing Module MFS5000SI.

In my IMS are 3 CI - and the optional Switch - each CI with an optional Mezzanine Card AXXGBIOMEZ.

Each CI is installed with MS Windows Server 2008R2 Enterprise. In the Windows-Eventlog, every 5 Minutes, i get the error:

Source: e1express - Event-ID 27

Intel(R) PRO/1000 PB Dual Port Server Connection Link has been disconnected.

and a second later:

Intel(R) PRO/1000 PB Dual Port Server Connection Link has been established: 1000Mbps.

I updated the drivers (16.6), set RSTP to off - but still the same.

The onboard "Pro/1000 EB Backplane" Nics are working fine, only the Nics on the Mezzanine Card reports the error.

Any Ideas ?

Are you seeing this error on all 3 compute modules? How are the NICs configured on each compute module? (each connecting to a different network, teaming, VLAN, etc.)

Hello,

thanks for your reply.

yes, this error appears on all computing modules.

to find out what is causing the error, we removed the configuration on the Switches - so no team, no vlan, all in the same network.

The Nics are "straight through the switch"

anyone an idea?

i'm currently using driver version 9.14.180.0, but i'd also tested older drivers.

Or could this be an issue with the second switch module inside the IMS ?

Did you swap the switch modules to test?

Good question... If I'm not wrong the switch configuration is on the switch itself... But I thought you said you have already removed all configurations on the switches?

Yes, for testing proposes i'd set the switch to default, but this did not solve my problem, so i reconfigured the switch.

Since you're using two switches, try disabling the switch interconnect - From the CMM GUI, choose System | Switches | Advanced Configuration

 

Mouse over any port and choose Port Configuration

 

Select Port | 10G.XC | Admin Status | Down

 

and Port | 10G.SC | Admin Status | Down
