Fan modules
Three fan modules, each containing one system fan (three system fans total), provide cooling for
director FRUs, as well as provide 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

SBAR assembly

The director ships with two SBAR assemblies. The active SBAR is responsible for Fibre Channel
frame transmission from any director port to any other director port. Connections are established
without software intervention. The assembly accepts a connection request from a port, determines if
a connection can be established, and establishes the connection if the destination port is available.
The assembly also stores busy, source connection, and error status for each director port.
