Pre-owned, used and refurbished Cisco CISCO837-K9

Cisco no longer supports the CISCO837-K9 router and recommends migrating to the CISCO877-K9 because the CISCO877-K9 offers more advanced security features. For customers that do not need the benefits these added features provide, we can help you save money on a pre-owned or used CISCO837-K9. All of our used routers are covered under a full one-year warranty, making your purchase risk-free. If you are ready to upgrade to a new surplus or refurbished CISCO877-K9, consider selling us your used CISCO837-K9 as this router offers high performance and availability, and is in high demand.

General Information
Manufacturer: Cisco
Product ID: CISCO837-K9
Product Description: Cisco 837 ADSL Router
Product Type: Router Appliance
Marketing Information
The Cisco 837 routers are asymmeric digital subscriber line (ADSL)-over-plain old telephone service (POTS) routing devices. They have an integrated 4-port Ethernet switch for the LAN and an ADSL physical interface for the WAN, allowing the routers to connect a corporate telecommuter or small office to corporate LANs and the Internet.

The routers support high-speed encryption, the 10/100BASE-T switch, and dial backup functionality via the auxiliary console port. The autosensing function in these routers eliminates the need for a crossover cable and allows the router to detect medium dependent interface in normal mode (MDI) or medium dependent interface in crossover mode (MDIX) in any other PC or hub with a straight-through cable or a crossover cable. The routers are capable of bridging and multiprotocol routing between LAN and WAN ports.

The dial backup feature allows the user to connect an analog modem to the console port as a backup link to the WAN in case the ADSL service goes down. This feature gives the Cisco 837 routers a high level of performance and security.

The Cisco 837 router is designed with both hardware-based and software-based encryption.
