是否可以通过 POST 错误消息修复 Cisco 3500 XL (3548) 交换机？

我有一台旧的 Cisco 3500 XL，它似乎有硬件问题。我已加载最新的 IOS 并清除了所有配置。

有人有修理开关核心的经验吗？我是一个相当熟练的 SMD 焊接工，我可以更换/回流一些芯片吗？

我检查了电源电压，一切都在允许范围内，没有任何部件损坏的迹象。有些芯片摸起来很烫。

我知道这些产品自 2007 年起就停产了，但电子产品应该享有终身保修。我没有思科支持合同，因此无法提交工单。我该怎么办？

我不会打扰。

您可以在各种网上市场上以几乎免费的价格买到二手开关，甚至是带有有限保修的翻新开关。

eBay 上售价约为 75 美元。何必费心修理呢。您自己花的时间可能更宝贵。
