HP NC523SFP 未檢測到鏈路
我有兩個 HP NC523SFP 10Gb 2 埠（一個在 HP DL380e Gen8 上，另一個在 Dell PowerEdge 2950 上）兩個系統都有 Centos 7，卡被檢測到並且執行相同的韌體。我已經使用 10Gtek SFP-H10GB-CU2M 電纜直接連接伺服器，根據其他一些在網上發現的文章看起來兼容（我也嘗試過使用 10Gtek SFP-H10GB-CU2M 電纜）但問題是之間沒有檢測到連結這兩張卡.. 在這些卡的另外兩個插槽上，我有光纖適配器 10Gtek AXS85-192-M3-Cisco2，它們通過 LC-SC 光纖電纜連接到 Cisco 交換機，但這些都沒有檢測到鏈路。這裡是兩台伺服器的 ethtool 輸出：

問題解決了，戴爾 2950 上的 enp8s0f0 埠壞了。我已經移動了 enp8s0f1 上的 DAC 電纜，現在我有了連結。確定這一點的測試是：
- 在 HP 上循環 DAC 電纜 -> Link OK
- 在戴爾上循環 DAC 電纜 -> Link KO
