Product sourcing insights & recommendations
The Cisco 3845 router is a legacy Integrated Services Router (ISR) that has reached its official End-of-Life (EOL) and is currently in a state of long-term obsolescence. While it remains a popular choice for secondary markets and lab environments due to its high modularity, it is no longer suitable for production enterprise networks due to the cessation of security patches and hardware support.
Product Overview & Legacy Value
The Cisco 3845 was designed for high-density enterprise branch offices, featuring a 3RU form factor that optimized concurrent services at wire-speed CiscoMountainview-Tech.
- Modular Capacity: 4 Network Module (NME) slots, 4 HWIC slots, and 4 PVDM slots, allowing for extensive voice and security expansion CiscoBbcusa.
- Performance Threshold: Optimized for T3/E3 WAN rates with a maximum theoretical throughput of approximately 350 Mbps, though modern workloads often push it to its operational limits CiscoMountainview-Tech.
Market Trends & Lifecycle Analysis
The global router market is shifting toward AI-driven and 5G-integrated infrastructure, with a projected CAGR of 14.9% reaching $25.3 billion by 2033 PersistencemarketresearchCisco.
- End of Life (EOL): Official Cisco support for the 3800 series ended in April 2011 CiscoCisco.
- Secondary Market Utilization: Today, the 3845 is primarily traded as refurbished hardware for training labs (CCNA/CCNP), legacy voice gateways, or low-cost routing where security is not a primary concern EbayFacebook.
- Migration Path: Cisco currently recommends transitioning to the Cisco 4000 Series ISR or Catalyst 8000 Edge Platforms for modern performance and SD-WAN capabilities Cisco.
Current Sourcing Landscape
Since new Cisco 3845 units are no longer produced, sourcing focuses on OEM manufacturers for similar 3RU form factors or refurbished distributors.
- Alternative Hardware: Modern 1U and 3U rackmount routers from manufacturers in Shenzhen offer significantly higher throughput (up to 3 Gbps) at a fraction of the legacy price .
- Supplier Availability: There are currently over 150 verified suppliers capable of providing custom-built integrated services routers with Gigabit Ethernet ports and rackmount configurations Alibaba.
