Cisco SG350 vs. CBS350-What’s the difference?

Over the past few years, the Cisco SG350 has established itself as the leading network switch for Dante applications. Functionality, convenience, and reliability, especially in essential audio applications, are just three of the primary features. Later, Cisco released CBS350 after a few years of development.

So maybe some people have several questions: is the range of functions similar, and hence may both kinds be swapped at any time? What’s the difference between SG350 and CBS350?

Introduction Differences

The Cisco 350 Series is a family of managed Ethernet switches with preset configurations. Models are available with Fast Ethernet ports ranging from 8 to 48 and Gigabit Ethernet ports ranging from 10 to 52, allowing you to build the perfect network foundation for your company.

The Cisco Business 350 Series Switches are a portfolio of economically managed switches that serve as a vital building block for any small office network. They are part of Cisco’s Business range of network solutions. Advanced features promote digital transformation, while ubiquitous security protects company important transactions, thanks to an intuitive dashboard.

Technical Specification Differences

The decimal point between the two series is the same for the processing capacity (packets per second and gigabits per second). Only the 16 port variants have seen a minor update. Due to its four uplink connections, the SG350 has a somewhat higher capacity than the CBS350, which only has two. When we consider Dante applications, which create a total load of just 1 Gbps even with 500 audio channels, all switches easily match our requirements.

	SG 350 Series		CBS 350 Series
	Millions of Packets per Second (mmps)	Switching Capacity in Gigabits per Second (Gbps)	Millions of Packets per Second (mmps)	Switching Capacity in Gigabits per Second (Gbps)
8 Ports	14.88	20	14.88	20
16 Ports	29.76	40	26.78	36
24 Ports	41.66	56	41.66	56
48 Ports	77.38	104	77.38	104
24 Ports (10G-Uplinks)	95.23	128	95.23	128
48 Ports (10G-Uplinks)	130.94	176	130.94	176

Serial Interface and USB Differences

You’ll never know which port has access to the switch management VLAN if you don’t know which port has access to the switch management VLAN. Alternatively, all ports are occupied. Alternatively, the switch does not reply to the expected IP address. In all of these circumstances, the switch can be accessed via the serial port without the need for an IP address or a VLAN assignment. This port was on the back of the SG350. After all, each switch included a serial cable. But which laptop these days has an RS232 interface? So, not only did you have to open the rack and fight your way to the backport, but you also needed the right USB-RS232 converter.

The CBS350 has two immediate advantages in this regard: on the one hand, the serial port is accessible from the front. They do, on the other hand, have a USB port! You’ll still need an adapter cable (since my CBS350 didn’t come with either a USB or RS232 cable), but you’ll save money on the USB-RS232 converter.

Optical Modules Differences

It’s reassuring that the supported SFP modules are generally the same, allowing modules to be swapped out as needed. In any case, the majority of modules on the market should work. However, if you rely on the original Cisco SFP modules, nothing will change.
