Can a UTP cable burn a Ethernet port?

By stoh ·
Here's the scenario.
I have a Cable Modem, a CAT5 UTP cable "punched" into a CAT5 RJ45 connector and a built-in Ethernet NIC connecting for broadband speed.

All went fine till recently, I found out there was no connection between my NIC and Cable Modem. No. the UTP cable was not faulty. To my surprise, I discovered that the Ethernet port jumpers and C95 (vicinity) were burnt! No other burnt marks were observed.

I changed the Ethernet port and the problem was solved.

I just want to know what caused my built-in Ethernet port to be burned? Was it that harmless-looking UTP cable? Or was there other contributing factors?

I would appreciate if someone will find the "culprit" for this "mystery" case.
Thank you so much.

Can a UTP cable burn a Ethernet port?

The UTP cable by itself will not do this mischief. Like any other cable, it's able to transmit electical pulses. My guess would be that you experience an elecrical surge somewhere that choose your Ethernet port as an outlet. Consider yourself lucky it's not the motherboard or the modem itself. This is just my guess.

i would say answer 1 is essentially correct but i would add something

you say it's a cable modem you connect to.. and the cable will hop from house to house and so is a probable source for all sorts of electric surges including direct or indirectlightning.

so to protect your computer i would suggest :
1 check the cable modem is firmly grounded (electrically :)
2 check the grounding of the cable splitter box.

hope this helps

I'm just kind of curious as to what kind of main board you have that you can replace built in devices? Is it a laptop or desktop?
