What He Said, in spades. 

Best bet is to lag-bolt the base of the rack to the floor if possible,
and to tie the back of the rack to a stud in the wall behind the rack. 
This is especially important for open racks with only one set of 
vertical supports, and only a bit less so for racks with two sets.

We had to do this where I was stationed in Japan, because the racked  
gear, when extended, wanted to pull the racks over, breaking the      
conduits leading power and signal in/out, and because the frequent    
small quakes and less-frequent (but pretty hairy) bigger quakes       
really came close to knocking over the racks even when all the gear   
was stowed.
