This is notification for the planned End of Life (EOL) of all Cisco ESR-5915 router based products, including the Parvus DuraMAR 5915 router (0X, -2X, and -3X variants), DuraMAR 31-5915 router, and DuraWORX 8043 router + computer. The last day to order the affected products is 15 November 2021. New orders are non-cancellable and non-returnable. All products must be shipped by 15 May 2022. The announcement is made in advance of the ESR-5915 Cisco technology becoming obsolete, in order to allow customers to assess any potential impacts, provide time to order sufficient products to maintain long-term program requirements, and/or to allow for a managed product migration to a new product.
