首先,不确定这个问题属于这里还是 SU,所以请在疯狂地投票或抨击我之前提出相应的建议。
我们有一个 UPS 设备,我们最近对其进行了配置以在我们的网络上工作。UPS 单元使用 AP9606 网卡,但也有用于终端使用的串行端口(腻子很棒)。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,当我们重新启动我们已配置为使用 UPS 设备自动关闭的机器时,UPS 上的 NIC 似乎只是删除了它的 IP 配置(仍在试图弄清楚这一点)。从那以后,任何尝试与 NIC 联系的尝试都失败了。
迄今为止尝试的步骤:
将我与 UPS 单元分开的唯一东西是 48p 开关,因此在同一子网内不应有任何网络过滤。我无法判断卡是否坏了,或者我是否真的必须按照这些说明尝试串行。因为我们继承了 UPS 单元,所以找不到这种智能信号电缆。但是,我手头有一根看起来可以工作的 Cisco YC 电缆,但我很难找到电线配置以查看它们是否匹配。OTOH,获得这条 APC 电缆也意味着我必须找到一台也有串行端口的过时计算机。

我曾经用 AP9606 配置了许多 SmartUPS,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:

而不是使用带有串行端口的 PC,我建议您只使用一根基于 PL2303 的 USB 转串行适配器电缆——它们适用于管理过去 10 年内发布的几乎所有操作系统的串行控制台内容。
好吧,它可能是专有的(从某种意义上说,它是一种非标准的引出线),但是如果您知道要寻找什么,则可以找到引出线图,并且如果您有一些便宜的工具,您也可以制作一个。
这是一个相当简单的:这是 0024C 模型:
