o
Start: start the ping messages sending by switch’s IP interface.

VeriPHY
VeriPHY is a function performed by Reason Switches to verify integrity of electrical
cables connected to the switch, for diagnostics purposes.
This function is performed directly at the PHY chips, which do interface between layer
2 and layer 1 communication. PHY chips inspect link quality majority based on the
impedance measured on each pair in a CAT-5 cable.
VeriPHY cable inspection can only be used in electrical cables, that is, CAT-5 or higher quality cables connected through a RJ45
connector. This function does not support Optical links.
While running on, VeriPHY function can disturb communication on the port that is being used by this function. Thus, if using
VeriPHY function, make sure in the period the function is running, there will be no major problem on data loosing.
Port:
Select the port that is requested to perform cable inspection by VeriPHY.
After one of the configurations described before is changed, there is a button that
allows the user to start the function, as follows.
o
Start: start the VeriPHY inspection.
The result is displayed in a table, where the rows represent the ports and the
columns each pair in a CAT-5 cable. Columns are divided by Pair (pair A, B, C and D)
and Length (Length of the pair A, B, C and D).
By default, all cells
are shown with the “
--
“ symbol. When the diagnostic is finished,
the results are shown to check if any problem was detected. Possible results are as
follows:
o
Pair column:
OK: means that cable is without injuries;
Open: means that the pair represented at this cell is open;
