Common Ports
The following ports are common among Cisco 3900 series, Cisco 2900 series, and Cisco 1900 series
routers:
• Gigabit Ethernet RJ45—Ports available through an RJ45 connector.
• Gigabit Ethernet RJ45/SFP—Ports available through RJ45- SFP connectors. Connection supports
fail-over if the secondary connection goes down.
• RS232 Aux—Supports modem control lines and remote administration for box-to-box redundancy
applications.
• RS232 Serial Console—Supports modem control lines and remote administration of the router with
the proprietary cable shipped in the box.
• Type A USB 2.0—Supports USB-based flash memory sticks, security tokens, and USB-compliant
devices.
• Type B mini-port USB Serial Console—Supports modem control lines and remote administration of
the router using a type B USB-compliant cable.
Licensing
Cisco 3900 series, Cisco 2900 series, and Cisco 1900 series ISRs support Cisco IOS software
entitlement. Your router is shipped with the software image and the corresponding permanent licenses
for the technology packages and features that you specified preinstalled. You do not need to activate or
register the software prior to use. If you need to upgrade or install a new technology package or feature
see Software Activation on Integrated Services Router,
