Re: [gsp-2101] Cooling my 2101

2006-09-08 by Adrian Teo

Keep an eye out on the unit if it runs hot. It's ususally a sign that  
one of the voltage regulator IC's in the back are going south.

You shouldn't have to need a fan. We've done a ton of rig installations  
where the 2101 is in a tight rack, which are shipped around (tossed  
around by roadies) and still function nicely for years despite the  
abuse and the limited air flow in the racks. A good rule of thumb is to  
keep the poweramps in a separate rack.
