2911 Front to Back Air Flow Converter
2911 Front to Back Air Flow Converter
The 2911 Air Converter forces the routers to take in (intake) air from the front (bezel) (Figure 5-42) and
allow it to go out through (exhaust) the back (business) (Figure 5-43). Installation of the 2911 Front to
Back Air Converter still allows the router to run over its full temperature operating range. The pieces of
the 2911 Air Converter are symmetric, and hence, if required, instead of the default 2911 side to opposite
side venting direction, they can be reversed to facilitate back-to-front air flow. The 2911 with 2911 Front
to Back Air Converter installed adds width to the router and requires it to be installed only in a EIA
23-inch rack. Based on the requirement, the rack mount brackets can be positioned on the front, centre,
Inside, or outside.
Note The installation of the 2911 Air Converter requires only two rack-mount brackets.

choose one of these four positions to install rack mount brackets.
