asterisk users - Feb 2006 - two tellabs 2572 echo board in a 253c mounting assembly?

Anyone gotten two of the 2572 echo canceller cards to work in a 253c mounting
assembly? I can get one to work, but when I install two, one always fails.
I've tried all my cards solo in the enclosure, on each side, and they all
work properly when only 1 is installed, however, when I install two, one of them
will come up, but the other always fails. Anyone know what might be causing
this? can't find any docs on the shelf thus far.

Thx in advance

Check to make sure that both cards aren't using the same address.

I have the cards set to auto address assignment, but changed it to shelf255d
setting (option 31) & still get the same behaviour... is there someplace
else that this can be set?

Thx!

Option 30 allows to set Module Shelf Address/ID.

I have tried it, and as far as I can tell, they both work, I did not
however test them both live with a T1 connected to both, just 1 T1
with both cards in, the lights settle on the other one without the T1,
while the first one with the T1 works, therefore I'm assuming it
works.
Are you sure that it is not working?
Are the lights on the other one out?
Do the lights come up at all?
Since they are hot swappable, try unplugging it and then inserting
them again, what happens? do the lights come on?
