Hi. I have installed a gb-mezzanine-card in my bl460c and the card is recognized (correctly) as a bge-interface. When I configure it with a valid ip-address status remain "no carrier". I have put the cable in two different switches, one managed and one un-managed. The switches do see the link as gbit, but link remains down. pciconf -vl | grep -A 3 -i "^bge" bge0@pci17:4:0: class 0x020000 card=0x1707103c chip=0c167914e4 rev=0xa3 hdr=0x00 vendor = 'Broadcom Corporation' class = network subclass = ethernet Likewise for bge1. dmesg | grep -i "^bge" bge0: <Broadcom unknown BCM5714, ASIC rev. 0x9003> irq 16 at device 4.0 on pci17 The mezzanine card has a 5715 chip according to the spec's. regards Claus
