Cisco Product Identification Tool
The Cisco Product Identification tool provides detailed illustrations and descriptions showing where to
locate serial number labels on Cisco products. It includes the following features:
• A search option that allows browsing for models using a tree-structured product hierarchy
• A search field on the final results page making it easier to look up multiple products
• End-of-sale products are clearly identified in results lists
The tool streamlines the process of locating serial number labels and identifying products. Serial number
information expedites the entitlement process and is important for access to support services.
The Cisco Product Identification tool can be accessed at the following URL:

Built-In Ports
Cisco 3800 series routers provide the following built-in ports:
• Two 1000BASE-T Gigabit Ethernet ports with RJ-45 connectors for shielded twisted pair. One of
these ports provides a slot for an optional small-form-factor pluggable (SFP) module.
• One RJ-45 console port for connecting to a terminal.
• One RJ-45 auxiliary port for connecting to a modem.
• Two built-in USB 1.1 ports to support USB devices qualified and approved by Cisco. No approved
USB devices are currently available, but enhancements are planned to provide additional flexibility
and functionality.
• Cisco Redundant Power System connector (Cisco 3825 router only).
