情况是我的 5548UP Switch 的软件版本非常旧：
Software
BIOS: version 3.6.0
loader: version N/A
kickstart: version 7.0(5)N1(1)
system: version 7.0(5)N1(1)
Power Sequencer Firmware:
Module 1: version v1.0
Module 2: version v0.0
Module 3: version v5.0
Microcontroller Firmware: version v1.2.0.1
SFP uC: Module 1: v1.0.0.0
QSFP uC: Module not detected
BIOS compile time: 05/09/2012
kickstart image file is: bootflash:///n5000-uk9-kickstart.7.0.5.N1.1.bin
kickstart compile time: 10/29/2014 22:00:00 [10/30/2014 07:30:37]
system image file is: bootflash:///n5000-uk9.7.0.5.N1.1.bin

我不知道它是怎么发生的，但似乎这个开关电源定序器版本比现有的 7.0(5)N1(1) 版本旧。我知道这是因为成对中的其他开关具有更新的电源音序器版本和相同的软件版本。我认为这可能是因为有人以错误的方式安装了这个设备 - 例如不是全部安装，而是设置引导变量并重新启动交换机。
所以，我在谷歌上搜索了升级软件的正确路径，下一步将是版本 7.1.4.N1.1，通过执行 show install all 影响我看到：

因此，通过查看这一切应该没问题，我将升级交换机，然后我将使用电源循环选项进行重新加载。
还有什么我应该采取行动的吗？这是某种不寻常的情况，因为当前的软件（我猜）没有以正确的方式安装。或者我可能需要重新安装当前的 7.0(5)N1(1) ？
