1A2,
Since you stated in an earlier post, you were able to access the system via web browser this indicates that this is a IPK II CPU. To default the system, pull all cards except the CPU, power down the system, hold down the SW toggle, (I don't remember which one) power up the system, keep holding the toggle while watching the LEDs on the CPU, when they begin to flash release the toggle. If this procedure doesn't work, try the other SW toggle. If it does work slot the circuit cards, slot the first card, watch the CPU, 1 of the LED's will flash, this indicates the card is being assign to that slot, 30 to 60 seconds after it stops flashing slot the next card, FYI the MIFM is not used.
