Outline of Cisco Full PoE 4x1G Uplink Switch

At-a-glance features and key search phrases

The Cisco C1-WS3650-48FS/K9 category centers on the Cisco Catalyst 3650 family: 48-port, full PoE (Power over Ethernet) switches with four 1G uplink ports. Common search terms and long-tail keywords that this category targets include “Catalyst 3650 48 port PoE switch”, “Cisco 3650 4x1G uplink full PoE”, “C1-WS3650-48FS/K9 specs”, “buy Cisco Catalyst 3650 refurbished”, “enterprise access switch PoE+ 48 port”, and “stackable 3650 switches for campus”. Optimizing content for these phrases helps the page rank for buyers, network engineers, and IT procurement teams seeking resilient access-layer switches with integrated PoE functionality.

Core capabilities

This category highlights devices built for enterprise access-layer deployments, branch offices, and converged networks where voice, video, wireless access points, and IoT endpoints require centralized power and robust switching features. Typical capabilities emphasized across this line include:

48 RJ-45 access ports with full PoE/PoE+ support to power IP phones, wireless APs, and cameras.Four dedicated 1 Gigabit SFP (or combination) uplink ports for flexible fiber or copper aggregation.
Layer 2 and Layer 3 switching features — VLANs, inter-VLAN routing, OSPF/EIGRP support (depending on software), and advanced QoS.
Stacking support enabling multiple switches to operate as a single logical unit for simplified management and increased resiliency.
Enterprise-grade security: 802.1X network access control, DHCP snooping, dynamic ARP inspection, and ACL capabilities.

Ports, Power, Uplinks, and Stackability

Port layout and PoE considerations

Searchers often want quick answers about port types and power budgets. The C1-WS3650-48FS/K9 variants typically provide 48 RJ-45 Ethernet ports with support for PoE (802.3af) and PoE+ (802.3at) to deliver up to the standard per-port power when properly provisioned. For practical purchasing decisions, emphasize:

Full PoE coverage: All 48 ports can supply power, making these switches ideal where every access port might require power (phones, APs, cameras).
Power budget planning: Mention that total available PoE budget depends on the internal power supply configuration or redundant power modules. Recommend buyers calculate expected per-port power draw (e.g., phones vs. high-power APs and cameras) and confirm total wattage supported by the selected model or optional power supply.
Port speed: Access ports typically support 10/100/1000BASE-T with auto-negotiation; uplinks are 1 Gbps to aggregate traffic to the distribution or core layer.

Uplinks — four 1G options and connectivity patterns

Uplink ports are critical for connecting to aggregation switches, routers, or fiber trunks. The “4x1G uplink” characteristic signals flexibility: administrators can use copper SFP (1000BASE-T) or fiber SFP modules (SX/LX) depending on distance and cabling.  

Use cases for 1G uplinks: campus aggregation, stacking uplinks, redundant links to distribution, or uplink to fiber backhaul. Module compatibility: SFP module options for multimode and singlemode fiber.
Link aggregation: LACP support for combining uplink ports into higher-throughput logical links.

Stacking and scalability

One compelling selling point of Catalyst 3650 series switches is stackability. Buyers searching “stackable 3650 48 port” want to know how many units they can stack, how stacking affects management, and whether stacking preserves PoE across members. Provide clear guidance:

Stack as a single logical switch: Multiple Catalyst 3650 switches can be deployed in a stack to provide simplified management and redundancy — operating as one control plane with distributed forwarding.
Why stack? Stacking increases uplink capacity, permits cross-module failover, and streamlines firmware upgrades and configuration changes.
Practical note: Verify stacking cable requirements and whether the specific SKU includes stacking modules or needs optional hardware.

Security, segmentation, and high-availability

Access control and threat mitigation

Security is a top search intent. Include content that answers queries for “3650 security features” and “Cisco switch 802.1X support”. Explain how the platform supports:

Redundancy and uptime

For customers evaluating risk, highlight high availability features: redundant uplinks, stacking resiliency, stateful failover behavior in stacked configurations, and the ability to maintain essential services during partial outages. Focus on search-friendly phrases like “high availability Catalyst 3650” and “redundant uplink design”.

Deployment scenarios and use cases

Campus access and wiring closets

This section helps buyers visualize where the C1-WS3650-48FS/K9 fits. Describe real-world applications:

Enterprise campus access: Dense endpoint scenarios such as classrooms, office floors, and meeting spaces — centralize PoE to power phones and APs while preserving uplink capacity.
Branch office consolidation: Replace multiple unmanaged switches with a single managed 48-port access switch — centralized VLANs, QoS, and security provide a consistent enterprise policy at remote sites.
Converged voice and video: Prioritize voice and video traffic with QoS policies while powering edge devices from the switch itself.

Wireless aggregation and IoT

Given the proliferation of APs and IoT devices, provide advice for wireless architecture and PoE planning: place APs on separate VLANs, reserve sufficient PoE budget for high-power APs, and ensure uplinks can carry aggregated wireless traffic. Use search terms like “PoE for wireless APs 3650” and “3650 switch for IoT”.

Cameras, access control, and surveillance

IP cameras are power-hungry and may require continuous power and bandwidth. Describe typical design patterns: use dedicated PoE budgets for camera-heavy ports, implement QoS for video streams, and consider separate surveillance VLANs to isolate traffic.

Throughput and forwarding capacity

Discuss expectations: buyers will search for “throughput Catalyst 3650” and “packets per second 3650”. Frame performance in practical terms: the series is designed for access-aggregation roles and supports line-rate forwarding for typical enterprise workloads, voice/video/ data convergence, and EVPN/SD-Access features depending on software licensing.
