[R-390] Rack question?

[Ronnie Davis]

Hello to all
I have a nice condition 5' Motorola rack cabinet that I plan on using to
store 3 R-390A's. How close can I mount them and not have to worry about
heat problems if all three are running? Should I just mount two in there and
leave extra space for air? It has two fans on it and im going to leave off
both doors, so only the sides will be covered. Any help will be greatly
appreciated.
Thanks
Ronnie
