SPEBlox D5 LED Purpose

What does D5 indicate? The other LED’s are all described in the spec. sheet, but D5 is not.

Typo in the datasheet.

That text should say D5, not D10.

Hi Josh,

I’ve seen D10 blink a bunch when Ethernet is active, but I’ve also seen D5 illuminate solid green in addition to D10 blinking:

I think the D5 description is missing from the spec. sheet.

Thank you,


Any updates on this? I believe the spec. sheet is missing info on D5.

D5 indicates 1000BASE-T activity. D10 is on when there is a 100BASE-T link.

Both are on with a 1000BASE-T connection on the four pair side.
