CHAPTER 4: DIAGNOSTICS
Cross D - Abnormal cross-pair coupling with pair D
- Length: The length (in meters) of the cable pair.
Buttons
Start: Press this button to run the diagnostics. This will take approximately 5 seconds. If all ports are selected, this can take
approximately 15 seconds. When completed, the page refreshes automatically, and you can view the cable diagnostics results in
the cable status table. Note that Diagnostics are only accurate for cables of length 7–140 meters.
10 and 100 Mbps ports will be linked down while running Cable Diagnostics. Therefore, running Cable Diagnostics on a 10 or 100
Mbps management port will cause the switch to stop responding until Cable Diagnostics is complete.
