XL710 no connectivity with Brocade ICX 6610 switch
I'm having the following symptom: Host 1 has a Intel XL710 card installed. If I connect the host to a Brocade ICX6610-48P switch via a 1m QSFP+ DAC (tried both a QSFP+ and a QSFP28 DAC), ethtool shows RX crc errors and no connectivity is possible except DHCP, which somehow works. Monitoring the port via the switch shows packets going out and in. Monitoring the port on Host 1 shows only packets going out. If I connect Host 1 to Host 2 (Mellanox CX3), everything works. If I connect Host 2 to the switch, everything works. If I connect Host 1 to Host 2 and Host 2 to the switch, and bridge the two ports of the CX3, everything works. Another user reported similar results: https://serverfault.com/questions/1117009/cant-get-new-nic-working/1140838 I do not currently have the capability to scope QSFP+ traffic, so no idea what's actually going on on the wire.
EN5339QI ， 10pcs X-ray has three structures
Dear Sir, we have 2K intel part EN5339QI, there are three structures after doing x-ray. we know EN5339QI is an Intel Enpirion Power System on a Chip (PowerSoC) DC-DC converter. It integrates the inductor, MOSFET switches, small-signal circuits. I would like to inquiry whether there is problem as below pictures. the left is inductor, I think they are more structures is not problem, right ? Inductance has no circuit, and its direction can be changed, which is a normal phenomenon, right? I am looking for your prompt reply. thank you very much!
