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

for Fibre Channel frame transmission from any director port to any other director
port. Connections are established without software intervention. The assembly
