Table 2 Meaning of the P117F Front Panel Buttons
Button Function Meaning
Select
The buttons determine what function will be displayed by the 17 Port
LEDs (the top two rows of LEDs).
The five Function LEDs (above the Select buttons) show which
function is currently displayed by the Port LEDs. The Port LEDs can
display either Link, Collision, Transmit, Receive or Full Duplex.
If, for example, the Link (LNK) LED is lit, then LEDs 1 to 17 will
display the Link status of every port.
(For P117FR ATM port LEDs, see also Table 4).
