The ESR-PRE3 Performance Routing Engine 3 is a high-performance control plane module featuring 2 GB DRAM and 128 MB flash, engineered to optimize routing throughput and stability in compatible Cisco routers.
The ESR-PRE3 offers 2 GB DRAM for large routing tables, 128 MB flash for IOS images, a multi-core CPU for fast packet processing, and standard control-plane security features.
ESR-PRE3 is compatible with Cisco modular platforms requiring a Performance Routing Engine 3, including the Cisco 7600 Series and select ISR G2/4000 Series routers.
Power down the router, remove the blank slot cover, insert the ESR-PRE3 module into the control-plane slot until the latches click, then secure the screws and power the router back on.
Yes. Upgrading from PRE2 to ESR-PRE3 is plug-and-play on supported chassis and delivers increased DRAM, flash memory, and CPU performance without additional licensing.
With 2 GB DRAM and a multi-core CPU, the ESR-PRE3 accelerates route convergence, supports larger BGP/MPLS tables, and reduces control-plane latency under heavy loads.
ESR-PRE3 supports Cisco IOS XE 16.x and later, Cisco IOS 15.x releases, and compatible feature sets for advanced routing, security, and MPLS services.
ESR-PRE3 provides 2 GB DRAM, which is critical for caching large routing tables, running advanced protocols, and ensuring high-speed lookup operations in enterprise networks.
The 128 MB flash stores the IOS image, system configuration files, and logs, enabling fast boot times and reliable firmware upgrades on the ESR-PRE3.
No. The ESR-PRE3 does not require an additional module license; it uses the router’s existing IOS licensing for feature activation.
Verify module seating and power, check console logs for POST errors, ensure the IOS version supports PRE3, and update to the latest firmware if required.
ESR-PRE3 consumes approximately 12–15 W, operates at 0–40 °C (32–104 °F), and supports 10–90% non-condensing humidity in standard enterprise rack environments.
ESR-PRE3 is covered by Cisco’s limited lifetime warranty and is eligible for SMARTnet® or Cisco Solution Support contracts for advanced hardware replacement and software updates.
ESR-PRE3 supports control-plane policing (CoPP), secure boot, hardware-accelerated encryption, and IOS software security features to protect routing infrastructure.
You can purchase ESR-PRE3 through authorized Cisco partners, certified resellers, or the Cisco online store with global shipping and support options.
After installation, load the latest IOS image, enable required routing protocols, adjust memory buffers via CLI, and monitor CPU/DRAM utilization for tuning.
