I have a BCM450 with an expansion cabinet. I tried to add a GATM8 card in slot 5 of the expansion. Went into element mgr and chose "catm8/gatm8" in the resources tab for slot 5. Then hit configure. When the next window pops up the dip switch settings field is blank. Its on 6.0 with the latest patches and has a CEC card. Any ideas?
