Question

Three Cat 5e cables were run from an office area to three computers in a machine shop. Work took place on the weekend when the machine shop was closed. The network is using 1000BaseT switches and all the NICs are 1000BaseT compatible. The longest run of cable is 85 meters. All cabling was certified and network connectivity was verified. On Monday, the users of the computers report very slow network performance and the switch reports CRC errors. What is the most likely reason for the problems

Answer 1

External EMI/RFI

Step-by-step explanation:

The EMI stands for Electromagnetic interference. It is a radio frequency spectrum which is disturbance that is created by the external source which affects the electric circuit by an electromagnetic induction or conductance. It is also called as the RFI or the radio-frequency interference.

In the context, the three Cat 5e cable were run from the office area to the three computers in the machine shop. The users reports a problem of a very slow network performance and also the switch reports CRC errors. This is mainly caused due to the external EMI or the external RFI.
