Asante MacCon IIsi SE/30, link light does not come on, but its on at the switch

[K Trueno]

Hi I have recently acquired (another, I don't have a problem I promise) SE/30 with an Asante MacCon, but when I plug it into the switch the light on the card does not come on.  It does come on though at the router end.

I have an existing SE/30 with a MacCon as well, and that machine does show a link light on both ends (same cable).  The only difference between the two is that are the connectors available:  The working one has the "Thick" and the RJ45 with a little switch, and the non-working one has the "Thick", RJ45, and BNC connectors.

Any quick thoughts?  I found a manual online and I didn't see anything obvious....

Asante Troubleshooter detects the card and passes the tests (minus the loopback and ping-pong one).

Thanks!

Success!  After more experimentation, it turns out the ribbon cable to the daughter card was flipped backwards.  So remember: white dot to white dot!

Don't know if it just never worked for the previous owner, or maybe it worked on the BNC / Thick connection the way it is, but there you go.  :?:

Wow! you're lucky that didn't fry anything!

I had that backwards as well because one of my ribbons doesn’t have a white dot.

It doesn’t seem to hurt anything because I seem to remember I did run it quite some time that way doing troubleshooting before I noticed it was backwards.

Gotta look at the pinouts again and see what gets connected when you flip the connector around.

Yeah, was confusing considering the link light on the hub/switch side was lighting up.  Supposedly that lights up with RX wires are working.

Yeah weird.  Which daughterboard do you have?  I have one with Thick and RJ45 (and a little slide switch), and the one that didn't work when flipped had Thick, Thin, and RJ45.
