The Cisco Ethernet Switch Module (ESM) for the Cisco 2010 Connected Grid Router (CGR 2010) can reduce your total cost of ownership by integrating Gigabit Ethernet (GE) and Fast Ethernet (FE) switch ports within the Cisco 2000 Series Connected Grid Router. This integration allows you to build redundant high-availability architectures and provides an all-in-one device to deliver advanced routing and switching, valuable for space-constrained environments.
