Catalyst 2960 PoE-48 Switch Issues After Water Exposure

[arsenzhanasbay]

Hello everyone,

I have a Catalyst 2960 series PoE-48 switch that was exposed to water during a rainstorm. The switch was located in a cross-connect cabinet under an open window, and several security cameras were connected to it. Since the incident, the cameras have stopped functioning.

Current Symptoms:

• The switch's fan is very noisy.
• All indicators go off, and port indicators freeze.
• Occasionally, when the fan is not noisy, the necessary indicators (like SYST) light up correctly, but this is rare.

Could anyone advise on where I should start looking to diagnose this issue? Is it possible to repair this on my own, or should I consider replacing the switch?

Thanks in advance for your help!

@arsenzhanasbay hi, if it got exposed to water there can be many circuit shorts and that can lead to component failures. specially the POE power. i suggest you to go to replacement. also this model is old and better move to recent model with support.

  - Usually that means that it's a fatal hardware problem as result of the water exposure.
    You may try to attach a console and have a cold start (power off/on) and check if there are any outputs on the console
    Last gasp actions could be factory reset , but I would not expect too much from that ,
