[c-nsp] X6708-10G-3C compatible with 7604 chassis?

[Tim Durack]

This might help you:

In the Cisco 6504 E, on the FAN-MOD-4HS fan-tray there is a switch at the
rear. This switch should be in the "A" position. See Figure 2.1.1.
This allows the fan to run in high-power mode. In this mode it generates an
airflow of 100 ft3/min per slot.

When the switch is in the "M" position it operates in the restricted-power
mode and generates only 75 ft3/min per slot. The WS-X6716-10GE line card
has a cooling requirement of 84 ft3/min. In this case it could prevent the
line card from powering up.

Note: on another FAN-MOD-4HS fan-tray the positions of the switch are
labeled "VARIABLE" and "FULL". The switch should be put in the "VARIABLE"
position.
