APC的智能信号电缆(940-0024)是否真正专有?

首先,不确定此问题是否属于此处或SU,因此请在疯狂否决或抨击我之前提供相应的建议。

我们有一个UPS单元,我们最近将其配置为在网络上工作。UPS单元使用AP9606网卡,但也具有看起来像是供终端使用的串行端口(put很棒)。我不熟悉后者。长话短说,我能够使用telnet配置网络适配器。一切都很好。

无论出于何种原因,当我们重新启动配置为使用UPS单元自动关机的计算机时,UPS上的NIC似乎只是丢弃了其IP配置(仍然试图找出答案)。从那时起,任何尝试与NIC联系的尝试都将失败。

到目前为止尝试的步骤:

  • 我按照这些说明手动进行了arp录入。
  • 点击重置按钮,然后重新尝试上一步。
  • 尝试之前的步骤时,运行WireShark,以查看NIC的MAC或IP是否出现在ARP请求的任何位置。

使我与UPS单元区分开的唯一一件事是48p交换机,因此在同一子网内不应有任何网络过滤。我没有任何办法来判断卡是否完好,或者我是否真的必须按照这些说明尝试进行串行操作。因为我们安装了UPS单元,所以找不到这种智能信号电缆。但是,我手头有一条看起来似乎可以使用的Cisco YC电缆,但是我很难找到电缆配置以查看它们是否匹配。OTOH,获得这条APC电缆还意味着我将不得不找到一台具有串行端口的过时计算机。

我曾经用AP9606配置了许多SmartUPS,但我不记得曾经需要“ APC专有”串行电缆。该记录的引脚看起来像一个简单的零调制解调器电缆交换的TX和RX引脚:

而且,我建议不要只使用一根基于PL2303的USB到串行适配器电缆,而应该使用带有串行端口的PC,它们可以很好地管理过去十年中发布的几乎所有OS的串行控制台内容。

嗯,它可能是专有的(从某种意义上说,它是非标准的引脚排列),但是如果您知道要查找的内容,则可以找到引脚排列图;如果您有一些便宜的工具,也可以制作一个。

这是一个非常简单的示例:这是0024C模型:
