M1000E - 10 GbE XAUI PTM no link with Brocade VDX 6740 10Gb switch

Issue

The Qlogic 10Gb Network adapter is showing inside the Windows OS as "Network Cable Unplugged"


 

Hardware configuration:

M610 Blade servers in M1000e chassis
 
Fabric A is onboard Broadcom BCM5709S NetXtreme II Gigabit Ethernet
Mezzanine Fabric B on the blade have Part# C583R – Qlogic 57711 10GB Ethernet NDC card
Mezzanine Fabric C on the blade have Part# W7KT8 – Qlogic QME2572 FC HBA card
 
Below are the I/O Modules used in the chassis

 
From the Dell 10GbE Pass through Module (XAUI), the network connectivity goes to the external Brocade VDX 6740 10Gb switch.
Under Windows 2008 R2 Std, the Qlogic 10Gb Network adapter is showing inside the Windows OS as "Network Cable Unplugged"
Under Device Manager -> Network adapter speed was set Auto Negotiate in the server end.
Similarly the Brocade switch port also was set to Auto Negotiate.



 

Solution

Manually set the Network adapter in the Windows OS to 10Gb Full Duplex and the Brocade switch port speed to 10Gb, after which the link came UP
 
The connectivity from blade server to the external Brocade switch is going through 10Gb Pass-through module (XAUI). after manually set the speed to 10Gb at both the ends, issue should be resolved.
