Cisco Catalyst C1000-48T-4G-L – Enterprise-Class Layer 2 Switch for Small Business and Branch Offices The Cisco Catalyst C1000-48T-4G-L is a fixed managed Gigabit Ethernet Layer 2 switch engineered for small businesses, branch offices, and critical IoT deployments. Featuring 48 x 10/100/1000BASE-T RJ45 ports and four 1G SFP uplinks, it delivers high-density wired connectivity for bandwidth-intensive environments. Powered by Cisco IOS Software, it combines reliable performance with intuitive management via CLI, web UI, or SNMP. Its rack-mountable 1RU form factor integrates seamlessly into standard equipment racks for structured wiring closet deployments. Key Features & Benefits 48 x 10/100/1000BASE-T Gigabit Ports – High-density RJ45 connectivity supports computers, IP phones, printers, cameras, and IoT devices at full Gigabit speeds. 4 x 1G SFP Uplink Ports – Flexible fiber uplinks allow seamless integration with core switches and backbone infrastructure for easy network expansion. 104 Gbps Switching Bandwidth / 77.38 Mpps Forwarding Rate – Non-blocking line-rate performance ensures smooth data transfers even under demanding loads. Advanced Security Features – Supports 802.1X authentication, ACLs, BPDU Guard, and SPAN for comprehensive network protection and policy enforcement. Cluster Management (up to 8 switches) – Multiple switches can be managed under a single IP address, reducing administrative overhead in multi-switch deployments. Energy Efficient Ethernet (IEEE 802.3az) – Ports dynamically sense idle periods and switch to low-power mode, reducing overall energy consumption. Cisco IOS Software – Proven operating system with CLI and on-box web UI plus Bluetooth console access for streamlined device and network management.
