On the ICP the Superconsole 1000 only works on the main control card (red-orange)pair, right?

That's the port that's pre-programmed for it (not sure on the pinout without the guide in front of me), but I believe that you should be able to program it on any digital port.

The default ICP only comes with two digital ports (the idea is for you to use IP-phones for the other ports). SS430/4150 have been phased out as sub-attendants, also. You'll need to use an IP-phone if you want sub-attendants.

I'm using IP pgones as sub-attendants, so maybe I could use the second digital port for the console? Thanks

You can put the console (or any compatible digital set on either port. They punch down on the WH/BL and WH/OR pairs.

the console goes on the r/bl or r/org pair on the on-board card on the ICP, or you can use it on a digital port if you're using a per node with digital card

Or use the 5540 IP console

Oops! Sorry for the typo... you're right, of course, its RD/BL and RD/OR

I moved it to the RD/BL pair and re-programmed. Works just fine, thanks!
