CISCO SB 24-PORT GIG POE+ SWITCH WITH 4 SFP

Searching for a switch offering performance, flexibility, and security to small to mid-size business networks? The Cisco Business CBS350-24FP-4G is the one for you. It has 24 gigabit RJ-45 ports, including PoE+ support, and 4 SFP uplink ports for fiber or long-reach connections. Whether powering IP cameras, wireless access points or switching traffic between VLANs, the switch provides robust capabilities in a compact package

Cisco places the entire Business 350 Series as an affordable managed switch line that simplifies deployment and management with the use of such tools as the Cisco Business Dashboard and embedded probe support.

Benefits & Features (Usable Bullets)

• IP phones, access points, and cameras may be powered via Ethernet without the need for additional power supply, thanks to full PoE+ compatibility and a 370 W budget.
• Performance bottlenecks are eliminated by the whole 56 Gbps switching fabric and wire-speed, nonblocking architecture.
• Premium Layer 3 routing features, including support for IPv4/IPv6, RIP v2, and PBR, allow you to route between VLANs without straining your router.
• Stacking feature — manage up to 4 switches as one logical switch, with cross-stack LAG, unified management.
• Robust security package — network access control (802.1X), ARP inspection, IP Source Guard, DHCP snooping, ACLs, and IPv6 first-hop defenses.
• Ease of deployment & management — Web UI with wizard mode, CLI, SNMP, and integration with Cisco Business Dashboard for centralized management.
• Resilient software infrastructure — two-image support for safe upgrades, stacking failover, hot-swap support.
• Energy efficiency — features like IEEE 802.3az, shutdown of ports on unused links, power adjustment based on cable length, and a mostly fanless design conserve energy.
• Rack-ready, small form factor — accommodates standard network wiring closets and racks without occupying too much space.

Use Cases & Real-World Scenarios

• Small/medium business core switch — ideal to aggregate and manage multiple devices (APs, servers, PCs) in centralized control.
• POE backbone for surveillance & WiFi — use the PoE ports to power cameras and access points, and backhaul via SFP links.
• Branch office networking — pile up multiple switches in a branch, switch locally between VLANs, and provide traffic resiliency.
• Voice (IP telephony) and data convergence — separate and give precedence to voice traffic (VLANs, QoS) while maintaining data throughput.
• Guest and secure user segmentation — quarantine guest VLANs, use ACL, and port-based security to protect corporate traffic.

Technical Notes & Tips for Integration

• The 4 Gigabit SFP uplinks offer flexible fiber or extended copper links — perfect for bridging closets or far-end segments.
• Because it supports dual image, you can load a firmware upgrade ahead of time without jeopardizing network downtime.
• With stacked implementations, link aggregation (LACP) can stretch across member switches both in terms of availability and bandwidth.
• In power-sensitive installations, you can program PoE shutdown on idle ports to save energy.
• Always mate SFP modules (e.g., Cisco GLC series) for compatibility and best performance.
• For heavy traffic or future growth, watch port and uplink utilization — the 56 Gbps fabric has some room to breathe but needs to be watched nonetheless.
