Product Features
Technical Overview
This switch operates at Gigabit Ethernet speeds across all ports, supporting 1000Base-T for twisted pair copper and 1000Base-X for fiber connections via the SFP slots. The 24 PoE+ ports comply with IEEE 802.3at standards, delivering up to 25.5W per port to connected devices.
The switch's modular design includes four dedicated SFP (mini-GBIC) slots that are not shared with copper ports, allowing simultaneous use of all 28 ports. Layer 2 switching capabilities enable VLAN segmentation, QoS prioritization, and advanced traffic management for optimized network performance.
Relevant factors for this section include Total Number of Network Ports, Uplink Port, Modular, Media Type Supported. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

The four SFP slots enable connectivity to fiber backbones or long-distance links between buildings, while the rack-mountable 1U form factor ensures clean integration into standard network cabinets. This switch serves as an ideal aggregation point for edge networks where both local device connectivity and uplink to core infrastructure are needed.
IP Surveillance Deployment
Power and connect multiple high-resolution IP cameras while maintaining network segregation for security traffic through VLAN capabilities.
Small Office Network Core
Serve as the central switching point for workstations, printers, and wireless access points with power delivery to reduce cable clutter and installation complexity.
Physical Profile
The switch features a standard 1U rack-mountable design measuring 1.73 inches in height, 17.52 inches in width, and 11.77 inches in depth. This compact form factor fits seamlessly into network racks while providing front-accessible ports for easy cable management. The steel construction and included mounting kit ensure secure installation in professional environments.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.73" (44 mm), 17.52" (445 mm), 11.77" (299 mm), 7.78 lb (3530 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

FAQ
How many devices can this switch power simultaneously with PoE?
The Cisco CBS350-24P-4G-NA has a total PoE budget of 195W across its 24 PoE+ ports. This allows it to power multiple devices simultaneously, with each port capable of delivering up to 25.5W. The actual number of devices depends on their individual power requirements - for example, it could power approximately 7-8 typical IP phones (7-10W each) or 4-5 wireless access points (15-20W each) while staying within the total budget.
What types of SFP modules are compatible with this switch?
This switch supports standard SFP (mini-GBIC) modules that are compatible with Cisco's 350 Series. You can use either copper SFP modules for additional Gigabit Ethernet connections or fiber SFP modules for optical connections. The switch supports 1000Base-X standards, making it compatible with a wide range of commercially available SFP transceivers for various distances and fiber types.
Is this switch manageable, and what management features does it include?
Yes, this is a fully manageable Layer 2 switch. It includes a comprehensive set of management features including VLAN support for network segmentation, QoS for traffic prioritization, IGMP snooping for multicast traffic optimization, port mirroring for network monitoring and troubleshooting, and spanning tree protocol for network redundancy. These features provide network administrators with control over traffic flow, security policies, and network performance.
What is the difference between the PoE+ ports and the expansion slots?
The 24 PoE+ ports are standard RJ-45 Ethernet ports that provide both data connectivity and power to connected devices (up to 25.5W per port). The 4 expansion slots are SFP ports designed for additional connectivity options - these accept SFP modules for either copper or fiber connections but do not provide PoE. All 28 ports can be used simultaneously, with the SFP slots typically used for uplinks to other switches or for longer-distance connections.
Can this switch be mounted in a standard network rack?
Yes, the Cisco CBS350-24P-4G-NA is designed for standard 19-inch rack mounting and occupies 1U of rack space. The package includes a mounting kit with the necessary brackets and hardware for secure installation. The switch dimensions (1.73" H x 17.52" W x 11.77" D) are compatible with most network cabinets, and all ports are front-accessible for convenient cable management.
What is the warranty coverage for this Cisco switch?
This Cisco switch comes with a lifetime limited warranty from Cisco. This warranty covers defects in materials and workmanship for the lifetime of the product. Cisco's warranty support typically includes replacement or repair of defective units, though specific terms may vary. The product is also WEEE compliant, ensuring environmentally responsible disposal options at end of life.
