6.6 Diagnostics VeriPHY

The VeriPHY Cable Diagnostics page is used to run the cable diagnostics for 10/100 and 1G copper ports.

Figure 6-8. Cable Diagnostics - VeriPHY

To run the diagnostics, click Start. This takes approximately 10 seconds. If all ports are selected, then this can take approximately 30 seconds. When completed, the page refreshes automatically, and you can view the cable diagnostics results in the cable status table.

Note: VeriPHY is only accurate for cables of length 7m–140m. 10 Mbps and 100 Mbps ports are linked down while running VeriPHY. Therefore, running VeriPHY on a 10 Mbps or 100 Mbps management port causes the switch to stop responding until VeriPHY is complete.

The VeriPHY Cable Diagnostics page has the following parameters:

  • Port: Port Number
  • Cable Status:
    • Port: Port Number
    • Pair: The status of the cable pair
      • OK: Correctly terminated pair
      • Open: Open pair
      • Short: Shorted pair
      • Short A: Cross-pair short to pair A
      • Short B: Cross-pair short to pair B
      • Short C: Cross-pair short to pair C
      • Short D: Cross-pair short to pair D
      • Cross A: Abnormal cross-pair coupling with pair A
      • Cross B: Abnormal cross-pair coupling with pair B
      • Cross C: Abnormal cross-pair coupling with pair C
      • Cross D: Abnormal cross-pair coupling with pair D
    • Length: The length (in meters) of the cable pair. The resolution is 3m.
