How many total network ports does the Netgear VSM4320C provide?

The Netgear M4350-16V4C VSM4320C provides a total of 20 network ports. These are arranged as 16 SFP28 ports operating at 25G and 4 QSFP28 uplink ports operating at 100G. This fixed 20 port configuration is useful for planning endpoint capacity, cabling, and uplink requirements in enterprise and AV network designs.

What type of access ports are available on the M4350-16V4C VSM4320C?

The switch includes 16 SFP28 access ports, each supporting 25G connectivity. These SFP28 25G ports are intended for connecting 25G capable AV or data endpoints, or for intermediate aggregation where 25G links are required. Their uniform speed and form factor helps standardize optics and cabling across deployments.

What uplink options are offered on the Netgear VSM4320C?

The M4350-16V4C VSM4320C provides 4 QSFP28 ports that support 100G operation and are typically used as uplinks. These 100G QSFP28 ports enable high bandwidth connections to aggregation or core switches. They are particularly useful when aggregating traffic from the 16 SFP28 25G ports into higher capacity backbone links.

How is the VSM4320C categorized for deployment planning?

The VSM4320C is categorized as an enterprise level fully managed AV network switch with 20 ports. This classification helps IT and AV teams position it appropriately in network designs, typically at access or distribution layers where managed control is required and both 25G edge ports and 100G uplinks are needed.

Is the Netgear M4350-16V4C suitable for AV focused networks?

Yes, the M4350-16V4C VSM4320C is specified as a fully managed AV network switch. Its combination of 16 SFP28 25G ports and 4 QSFP28 100G uplinks, along with its enterprise product level, makes it suitable for AV over IP environments that need managed switching, defined port counts, and clear separation between access and uplink capacities.
