Remember the Ascend MAX TNT and the sideways left-right airflow? The preferred method of deployment was three tall in a two post rack, mid mount.
Shoot, only three tall? With the original dual-slot modem cards and separate HDLC cards, it took three chassis just to handle one DS3. Throw another couple in there to start the next DS3 and get cooking! Of course, they came in the crate with that little piece of sheet metal air deflector that I don't think I ever saw how to mount. We had something (Redback SMS-500?) that also cooled side-to-side, but in the opposite direction; had to make sure it was "upwind" of the TNTs. -- Chris Adams <cma () cmadams net>
