ConnectX-6_Dx LED behavior and connection status

Infrastructure & Networking Adapters and Cables Ethernet Adapter Cards
1

I have 2 question, please help to figure out.

  1. I checked the EVK’s LED D1 and D3 behavior as below:
    a. D1/D3 yellow LEDs are link status but they don’t light on.
    b. D1/D3 green LEDs are traffic status, they always light on after command “ifconfig eth down”
    As I checked the schematic, the LED D1/D3 control by pin D12, G13, D21, G12
    Could you check the LED behavior?
  2. When loopback test by 2 port and key the command “ifconfig eth1 down”
    The Link detected on eth1 status is no but the eth2 ststus still is yes.
    I don’t understand why the disconnect 2 port that status not same.
    Thanks.

Hellow howard_lee,

This is Cho from Nvidia Technical Support.
Regarding 1st question, please check the LEDs status
There are two I/O LEDs per port to indicate speed and link status.
LED1 is a bicolor LED (amber and green) and LED2 is a single color LED (green).

State Led1
Physical Link Speed		 Led2
Logical Link/Activity
Beacon command for locating the adapter card 1Hz blinking amber/green according to high/low speeds OFF
Error 4Hz blinking Amber indicates a problem with the link ON
Physical Activity • A constant Green indicates a physical
link with the highest-rated speed.
• A constant Yellow indicates a physical
link with degraded speed.		 Blinking
Link Up • A constant Green indicates a physical
link with the highest-rated speed.
• A constant Yellow indicates a physical
link with degraded speed.		 ON

2nd question, please try to execute command both interfaces.

Thank you,
Cho
