[c-nsp] APC Cabinets with SIde Air Distribution

[Simon Hamilton-Wilkes]

The best solution for this is the 6509 NEB chassis.  Failing that I've
installed 6513's in 2 post racks rather than 4 post - as the attached cable
management gave a good 6 or 8 inches of airspace.

 We are in the process of a hardware refresh on our core network which will
see about 10 Catalyst 6500's replace existing 6006's and older 6509's. All
will have either Sup 720 or Sup 32. Hardware has been ordered and is
arriving daily.

 I am interested in what others are doing to accommodate hot isle/cold isle
configurations with the cold isle in the front of the cabinet? As most of
you are aware the fan tray on the 6500 is on the left side drawing cool air
in the left and expelling hot air out the right. With our current
configuration we have cabinets with an outside measurement of 22" which
leaves very little room for air flow on the sides, shortly after installing
this equipment in 1999 we wound up removing the sides of all cabinets. Of
course this resulted in the exhaust from one switch being drawn in the
intake of the next.

 We want to fix this situation with this hardware refresh project and have
been looking at the APC 29" wide cabinet (PN AR3150) with APC's Side Air
Distribution Fan (PN ACF201BLK).

  Can anybody comment on this setup? Or perhaps offer different/better
solutions for air flow management?

 Thanks for your comments, and or advice.
