Fan Modules
Two fan modules, each containing three fans (six fans total), provide cooling for
director FRUs, as well as providing redundancy for continued operation if a fan fails.
The fan module can be replaced while the director is powered on and operating,
provided the module is replaced within 10 minutes (after which software powers off
the director). An amber LED for each fan module turns O
N if one or more fans fail or
rotate at insufficient velocity.
