CF-6801 Cooling Frame
Overview
The CF-6801 is a one rack unit (1RU) frame fan tray with a high-airflow
fan array. It provides redundant, low-noise cooling for up to two 2RU
frames of equipment (4RU), or up to twenty 6800/7000 series modules.
This fan array provides 40 cubic feet per minute (cfm) of airflow,
evacuating from the frames below it, and exhausting into the rear of the
rack.
Installation Requirements
The CF-6801 cooling frame is installed above the FR-6804(-1) frame in
two possible configurations (see Figure 4-1). The vents on the bottom of
the cooling frame match those on the top and bottom of the FR-6804(-1)
frame. Cool, ambient air is drawn in through the dust filter at the front of
the FR-6804(-1), passed through its modules, and then drawn up
through the frame slots and into the CF-6801 cooling frame. The hot air
is exhausted from the back through the use of a ten-fan array.
The CF-6801 cooling frame is mounted directly above the FR-6804(-1).
The CF-6801 frame requires 1.75 in. (44 mm) of rack space with a depth
from the mounting surface of 11 in. (280 mm).
The CF-6801 supplies forced
air cooling for the power
supply and the frame. If power
consumption is greater than
40 W, this Cooling Frame is
required.
