PCMech: Protect Your Electronics From Electricity
 

It is common practice to protect expensive equipment such as TVs and computers from
electrical surges with surge protectors. I practiced this very well. All the
desktops in my house were connected to surge protectors. All the TVs in the house
were likewise connected. However, there were two things that were not protected:
one Ethernet switch, and the cable lines. The results of these two devices not
being connected may surprise you.
