Cisco C-SM-40T8M2X Catalyst 8000 SM-Based Switching Module, 50 Ports, 40x 1G RJ45, 8x 2.5G Multigigabit, 2x 10G SFP+, Non-PoE

The Cisco C-SM-40T8M2X is a double-wide switching module for Cisco Catalyst 8300 Series Edge Platforms. It adds integrated branch LAN switching to the router, helping consolidate LAN and WAN services into a single platform.

This module provides 50 total ports, including 40 x 1G RJ45 ports, 8 x 2.5G Multigigabit RJ45 ports, and 2 x 10G SFP+ uplinks. The SFP+ uplink ports support either 1G SFP or 10G SFP+ operation, giving flexibility for fibre uplinks, aggregation, or server connectivity.

Based on Cisco naming and channel listings, the C-SM-40T8M2X is the non-PoE version of the 40-port double-wide switching module. It is well suited to branch deployments that need dense copper access and multigigabit capability, but do not require PoE power delivery.

The Catalyst 8000 SM-based switching architecture supports enterprise-class branch features including Layer 2 switching, VLANs, EtherChannel, LACP, PAgP, 802.1X device authentication, Cisco TrustSec, and 128-bit MACsec. It also uses the host Catalyst 8300 platform and integrates with Cisco IOS XE for simplified management through a single platform.
