Cisco 1750 Modular Access Router End-of-Sale Announcement

Product Bulletin No. 1660

Cisco 1750 Modular Access Router
End-of-Sale Announcement

This Product Bulletin serves as the formal notification of the End of Sales (EoS), End of Engineering, and End of Life (EoL) for Cisco 1750, Cisco 1750-2V, and Cisco 1750-4V router models along with associated spares and bundles. The replacement product is the Cisco 1751 Modular Access Router. All Cisco 1750 customers are advised to transition to the Cisco 1751, which offers new features, higher performance, and twice the default memory for the same price (see Table 1 for Cisco 1750 and Cisco 1751 feature comparisons). Table 2 lists Cisco 1750 SKUs affected by the End-of-Sale announcement. Key dates for EOS/EOL are detailed in Table 3. The replacement products are detailed in Table 4.

The Cisco 1750 has won many industry awards and had offered a platform to converge voice and data networks for small and medium-sized business (SMB) and enterprise small branch office customers. The introduction of the Cisco 1751 has taken the successes of the Cisco 1750 to the next level, leading to the EOS of the Cisco 1750 platform. Reasons for this action include:

  • Customers have demonstrated clear preference for Cisco 1751 since its introduction, leading to a dramatic decrease in Cisco 1750 sales

  • New Cisco IOS® images with voice features will require memory beyond the maximum available memory

  • Manufacturers are discontinuing some components used in the Cisco 1750

The Cisco 1751, introduced in May 2001, delivers new features, higher performance, and more memory at the same price as the Cisco 1750. Table 1 details the advantages of the Cisco 1751 platform. For more information on Cisco 1751, please go to Cisco 1751 data sheet at:

Support Programs

EoS refers to the time when products are no longer available for new purchases; it does not apply to the service and support programs for those products. Cisco will continue to support the listed products through its SMARTnet and comprehensive maintenance programs. Customers with either of these service contracts are entitled to free software updates, 24-hour phone support through the Technical Assistance Center, and advanced replacement of hardware for repairs. Comprehensive maintenance customers also receive onsite service. Customers who do not have a maintenance contract can purchase software updates and hardware repair services from Cisco to meet specific requirements rather than full-service coverage. Cisco is committed to providing software support for a minimum of two years and providing technical support for a period of five years after the EoS date.

Software Support

Cisco 1750 family is supported in Cisco IOS Software releases through Cisco IOS 12.2.8T and Cisco IOS 12.3 Mainline.
