When you look at DSLAMs, they throw it [the term] in your face.

Whoopsie! Looks like I need to move up that maintenence on our TuCows
Mirror. IIRC, it's being cooled by convection. The power supply fan is
turning very slowly... I have one (personal) machine that used to host
some 5.25" full-height SCSI drives. It's equip'd with a 12V fan in the
upper back of the full tower. There is a 120V AC fan installed just inside
the case; basically, the 12V fan is sandwiched between the 120V fan and
the case wall. After commiting the machine to "inactive" status (powered
24x7, I use Netscape on it and another machines as an X terminal), I
noticed the fan had failed. Being that the fan air exit is a Gaping
Hole(tm), I keep a fan moving so that air doesn't stagnate. Turned on the
120V fan, walked away..
