I think that's insane (no offense intended).  same with the comment about 
crash carts being hard to maneuver.

the management network should be constantly used for monitoring; never 
testing or using it is a serious admin failure IMO.  having enough 
obstructions in your machineroom that you can't move a small cart around
is also a serious failure: such a room would necessarily also have 
disasterous airflow, etc.
