Cisco cable test impedance mismatch
WebOct 21, 2024 · I have access to a high end cable tester and found that when testing ports running at 1Gb/s the Meraki results are very good with the only caveat being that the … WebThe "Open" state indicated a break in one of the pairs of cable during the UTP wiring path, and the "Short/Crosstalk" state occurs when the signal of one cable is mixed with the signal of another cable. It can happen when the cables are damaged or you have a worn or broken RJ45 plug. This produces the "short circuit" effect on the signal.
