Caution
You must use only the Cisco SD card designed to support the router. Using an unsupported SD card can
impact the router performance, especially in extreme environmental conditions.
10/100BASE-T Fast Ethernet Connector
The router has an external Fast Ethernet (FE) connector (see
Figure 3-7
) that enables you to connect the
router to an Ethernet hub or switch without opening the chassis.
The external connector is connected to the one of the fast Ethernet ports inside the router chassis. The
internal port used depends on the router hardware configuration. If you are connecting the external
Ethernet connector to an internal Ethernet port for the first time, Cisco recommends you connect it to
the ETH 2/5 port. For more information, see the
“Fast Ethernet Ports” section on page 3-22
