Cisco Catalyst 3650-48TS-E Switch - C3 - Managed - 48 x 10/100/1000 + 4 x SFP - Desktop Rack Mount

Cisco Catalyst 3650-48TS-E Switch

The Cisco Catalyst 3650-48TS-E is a high‑performance, fully managed Layer 3 switch designed for enterprise edge and distribution layers. With 48 Gigabit Ethernet ports and four SFP uplinks, it delivers robust connectivity while supporting advanced routing, security, and management features that enable modern data center and campus networks to operate efficiently.

Design & Form Factor

This model is engineered for desktop rack mounting, fitting comfortably into a 1U rack space. Its compact footprint allows it to be deployed in tight environments such as small office branches, remote sites, or data center edge racks where space and power density are critical.

• Dimensions: 44 mm (height) × 442 mm (width) × 100 mm (depth)
• Weight: Approximately 2.5 kg
• Power Supply: Dual redundant power supplies optional, each providing up to 300 W of capacity.

Port Configuration

The switch offers a balanced mix of copper and optical connectivity:

• 48 × 10/100/1000Base‑T RJ45 ports – Full‑duplex, auto‑negotiation, supporting up to 1 Gbps per port.
• 4 × SFP (Small Form‑Factor Pluggable) uplinks – Compatible with 1 GbE or 10 GbE transceivers, enabling flexible fiber or copper uplink options.
• Optional PoE+ support on selected ports for powering IP phones, wireless access points, and other PoE devices (up to 30 W per port).

Layer 3 Routing Capabilities

The Catalyst 3650-48TS-E is a fully managed Layer 3 switch, providing static routing, OSPF, EIGRP, and BGP support. This allows it to perform as an edge router while still delivering high‑speed switching performance.

• IP Routing: Supports IPv4 and IPv6 routing protocols with route summarization and redistribution.
• VLAN Routing (SVI): Each VLAN can be assigned a dedicated IP interface for inter‑VLAN communication.
• Quality of Service (QoS): Classifier, scheduler, and policing features to prioritize voice, video, and critical data traffic.
• Access Control Lists (ACLs): Both standard and extended ACLs can be applied per interface or globally for granular security.

Security Features

Security is integral to the Catalyst 3650 series. The switch incorporates a suite of features designed to protect network integrity and data confidentiality:

• 802.1X Port‑Based Authentication: Enables dynamic VLAN assignment and access control based on user credentials.
• MAC Address Filtering: Restricts device connectivity at the port level.
• Dynamic ARP Inspection (DAI): Prevents ARP spoofing attacks by validating ARP packets against DHCP snooping tables.
• IP Source Guard: Associates IP addresses with MAC addresses to stop IP spoofing.
• Port Security: Limits the number of MAC addresses per port and can shut down a port if violations occur.

Management & Automation

The switch supports multiple management protocols, making it easy to integrate into existing network operations centers (NOCs) or automated infrastructure frameworks:

• SNMP v1/v2c/v3: For monitoring and configuration via standard network management systems.
• REST API: Enables programmatic control for modern automation tools such as Ansible, Terraform, or custom scripts.
• CLI (Command Line Interface): Full Cisco IOS XE command set for detailed configuration and troubleshooting.
• Web UI: Graphical interface for quick setup and status monitoring.
• Syslog & NetFlow: Centralized logging and traffic flow analysis for performance tuning and security auditing.

Stacking Capabilities

The Catalyst 3650-48TS-E can participate in a stacking configuration, allowing multiple switches to operate as a single logical device. This simplifies management, increases port density, and provides redundancy:

• StackWise Virtual (SWV): Enables up to eight switches in a stack with a virtual MAC address and IP.
• Redundant Stack Links: Dual 10 GbE uplinks for high availability between stacked units.
• Unified Configuration: One set of VLANs, ACLs, and routing tables across the entire stack.

Power Options & Energy Efficiency

The switch is designed to be energy efficient while offering flexible power solutions:

• Dual Redundant Power Supplies: Each unit can provide up to 300 W, ensuring continuous operation even if one supply fails.
• Energy Efficient Ethernet (EEE): Low‑power mode for idle ports reduces overall energy consumption.
• Power over Ethernet (PoE+): When enabled, PoE+ ports can deliver up to 30 W per port, supporting a wide range of devices without additional power infrastructure.

Deployment Scenarios

The versatility of the Catalyst 3650-48TS-E makes it suitable for various network environments:

• Enterprise Campus Edge: Provides high‑density connectivity with Layer 3 routing, PoE+ for access points, and robust security features.
• Branch Office Distribution: Compact form factor and stacking support allow easy scaling as the branch grows.
• Data Center Edge: Fast uplinks via SFP ports and advanced QoS help prioritize critical workloads.
• Remote Sites: Dual power supplies and PoE+ reduce cabling complexity in locations with limited infrastructure.

Conclusion

The Cisco Catalyst 3650-48TS-E Switch delivers a powerful combination of high‑throughput switching, Layer 3 routing, advanced security, and flexible management. Its compact rack‑mount design, PoE+ capability, and stacking support make it an ideal choice for enterprises seeking to build resilient, scalable, and secure networks without compromising on performance or space efficiency.
