[DuoList] Cannibalizing a 2400 to upgrade another

[Ralph Mawyer]

Susanna, the G3 card is plug and play, once you get the 2400 open.   
You could actually swap cards and verify both 2400s and the cards with  
a swap, i.e., if the new host for the G3 has problems, then it's the  
card.  The display could just be a connection given the symptoms.   
Make sure you have the G3 cache software loaded, but I assume you do  
since you've had it awhile.
