我有一台带有 447325-001 电源背板的旧 Proliant DL185 G5 服务器。两个连接器似乎很有趣，一个看起来像 ATX 电源连接器，将绿色连接到 GND 会启动所连接的 449840-002 的风扇。第二个标记为 RPS，是一个小型连接器，有 12 个引脚。
问题是，任何引脚都没有电源输出。查看 DL185 的服务手册，RPS 连接器似乎连接到“MT9 冗余电源管理接口连接器”
我搜索了任何关于 RPS 引脚排列的描述，但均未成功。我是否需要使用此连接器从 PSU 获取电源？如何在没有主板的情况下从 PSU 获得电源？
--- 更新 2 --- 从未解决 Xcp-Ng 7.6。xcp-ng 8.0 不存在问题。
我有一个 Intel Xeon X5650 处理器（来自 eBay），但 linux（Xcp-ng 7.6）只列出了 8 个使用lscpu. 但是dmidecode -t processor正确地说明了 6 个内核和 12 个线程。
我尝试更新 BIOS 和 Xcp-Ng 并添加maxcpus=12 nr_cpus=12到内核行。不幸的是，我不知道是什么原因造成的，也不知道如何继续寻找解决方案。
--- 更新 ---- 禁用超线程给了我 6 个核心，但每个核心只有 1 个线程 -- /UPDATE ---
