FAN module 21
FAN module The Router 6040 and Router 6080 are equipped with pairs of FAN
cooling modules. The two fans in each pair work together to provide
redundancy. The failure of one fan does not affect the operation of the
other fans, and normal system operating temperature can be maintained.
The speed of the fans is controlled by the RPU or RPU2 to maintain
optimum system temperature. If a fan stops working, the RPU or RPU2
will display an alarm.
The following figure shows a FAN module, using the 3Com Router 6080
as an example.

Auto-Config With the automatic configuration (auto-config) feature, your
Router 6000 can automatically detect and configure all its interfaces
upon its first use and start Telnet, FTP, or Web service. Then the connected
router or console terminal that has been pre-configured at the network
center automatically connects to the router to configure it or to transfer
the configuration file. Alternatively, this connection can be initiated
administratively.
