HP NC523SFP no link detected

0

I have two HP NC523SFP 10Gb 2-port (1 on a HP DL380e Gen8 and the other on Dell PowerEdge 2950) both systems have Centos 7, the cards are detect and are running the same firmware. I have connected directly the servers with 10Gtek SFP-H10GB-CU2M cable which according to some other posts found online looks compatible (I've tried also with 10Gtek SFP-H10GB-CU2M cable) but the problem is that the link is not detected between the two cards.. On the other two slots of these cards I have the fiber adapters 10Gtek AXS85-192-M3-Cisco2 these are connected to a Cisco switch with an LC-SC fiber cable but neither these gets the link detected. Here the ethtool output from both servers:

DL380e Gen8 (seems that both fiber and copper transreceiver are recognized)

What can I check? I have tried to force the link speed but I get "Operation not permitted" I noticed that on the Dell the copper cable is detected as "Port: Other"

Problem solved, it's the port enp8s0f0 on Dell 2950 broken.. I have moved the DAC cable on enp8s0f1 and I have the link now. The test to determinate this was:

  • Looping the DAC cable on HP -> Link OK
  • Looping the DAC cable on Dell -> Link KO
