Cisco Business CBS350-48P-4G 48-Port Gigabit PoE Managed Network Switch

Cisco Business CBS350-48P-4G 48-Port Gigabit PoE Managed Network Switch

Running IP phones, wireless access points, and security cameras across a growing office network shouldn’t mean running separate power adapters and cabling for every single device. The Cisco Business CBS350-48P-4G solves that problem directly, delivering 48 Gigabit PoE+ ports that power and connect network endpoints through a single Ethernet cable each, backed by the security, management sophistication, and reliability that has made Cisco the standard reference point in enterprise networking for decades.

This is a genuine managed switch from Cisco’s Business 350 Series, built for small and medium businesses that need enterprise-grade network infrastructure without enterprise-grade complexity or cost.

48 Gigabit PoE+ Ports With a Genuine 370W Power Budget

The CBS350-48P-4G provides 48 x 10/100/1000 Gigabit Ethernet ports, every one PoE+ compliant, backed by a 370W total power budget supporting up to 30W per port. This means IP phones, wireless access points, and IP surveillance cameras can all draw power directly through their network cable, eliminating the need for separate power supplies and adapters at every device location — a genuine simplification of both installation and long-term cable management across an office or facility.

Why Eliminating Separate Power Supplies Actually Matters

Every device requiring its own power adapter represents an additional point of installation complexity, an extra cable run, and a potential failure point over the network’s operating life. By powering compatible devices directly over Ethernet, the CBS350-48P-4G removes this complexity across up to 48 simultaneous connections, meaningfully simplifying deployments involving IP telephony, wireless access points, or IP-based security camera systems.

4 Gigabit SFP Uplink Ports for Flexible Network Expansion

Beyond the 48 access ports, the switch includes 4 additional Gigabit SFP uplink ports, providing fiber connectivity options for linking to core switches, other network segments, or extending connectivity across a larger facility. This uplink flexibility supports growing network topologies without forcing a switch replacement as infrastructure scales.

104 Gbps Switching Capacity for Demanding Network Loads

With a total switching capacity of 104 Gbps and a forwarding rate of 77.38 million packets per second, the CBS350-48P-4G handles genuinely demanding data loads efficiently, supporting file transfers, VoIP traffic, and video surveillance streams simultaneously without introducing network bottlenecks.

Layer 2 and Layer 3 Features for Serious Network Management

Operating with both Layer 2 and Layer 3 capabilities, the CBS350-48P-4G supports VLANs (up to 4094), static routing, and quality of service (QoS) configuration, giving IT administrators genuine control over traffic segmentation and prioritization across a growing business network. Advanced security features including 802.1X authentication, DHCP snooping, dynamic ARP inspection, and IPv6 first-hop security protect the network against unauthorized access and common network-based attacks.

Cisco Business Dashboard for Simplified Management

The switch integrates with the Cisco Business Dashboard and mobile app, giving IT administrators an intuitive, web-based interface for configuration, monitoring, and lifecycle management, rather than requiring extensive command-line networking expertise to operate effectively. True stacking support allows multiple switches to be managed as a single unified device, simplifying administration as a network grows across multiple switches.

Fanless, Quiet Operation for Noise-Sensitive Environments

The CBS350-48P-4G’s fanless design provides genuinely quiet operation, making it suitable for deployment in offices, classrooms, and other noise-sensitive environments where a fan-cooled switch’s constant background hum would be a genuine distraction.

Energy Efficiency Built In

Support for IEEE 802.3az Energy Efficient Ethernet reduces power consumption during periods of lower network activity, contributing to lower operating costs over the switch’s service life without sacrificing performance when the network is under genuine load.

Backed by Cisco’s Global Reputation and Lifetime Limited Warranty

As part of Cisco’s Business 350 Series, the CBS350-48P-4G carries a lifetime limited warranty, reflecting the same manufacturer confidence found across Cisco’s broader networking portfolio — the same brand trusted at the core of data centers and enterprise networks worldwide, now scaled and priced for small and medium business deployment.
