LED
Scheme 1: One Bi-Color LED
There is one bicolor(Yellow and Green) I/O LED per port to indicate speed and link status.
Physical and Logical Link Indications
State Bi-Color LED (Yellow/Green)
Physical link speed
Beacon command for locating the adapter card 1Hz blinking Yellow
Error 4Hz blinking Yellow indicates a problem with the link
Physical Activity • A constant Green indicates a physical link with the
maximum networking speed.
• A constant Yellow indicates a physical link with less than
the maximum networking speed.
Link Up • A constant Green indicates a physical link with
themaximum networking speed.
• A constant Yellow indicates a physical link with less than
the maximum networking speed.
Scheme 3: One Bi-Color LED and one Single Color LED
There are two I/O LEDs per port to indicate speed and link status. LED1 is a bicolor LED (Yellow and
green) and LED2 is a single color LED (green).
Physical and Logical Link Indications (Ethernet Mode)
