Description: The Cisco SM-D-ES2-48 is a discontinued product, and Cisco stopped selling it in October 2020 [Cisco EOS Announcement]. However, you may be able to find used modules from third-party vendors. The SM-D-ES2-48 is a good option for expanding the number of Ethernet ports on a Cisco 2900 or 3900 series router. It is important to note that the SM-D-ES2-48 is a Layer 2 switch, which means that it cannot route traffic between different networks. If you need a switch that can route traffic, you will need to consider a different model. The Cisco SM-D-ES2-48 is a modular Layer 2 Ethernet switch service module that can be installed in Cisco 2900 series and 3900 series routers. It provides 48 10/100/1000BASE-TX ports, which can be used to connect devices to the network. The SM-D-ES2-48 also includes two SFP ports that can be used for uplink connections to other switches or routers.
