Faster access is valuable only along a complete path

The M4350-24X4V is a substantial step beyond a Gigabit AV edge. Its 24 copper ports reach 10Gb, while four SFP28 interfaces provide 25Gb connections. That permits a faster encoder, workstation or other supported endpoint to connect without first changing to a fiber network card.

The arithmetic also exposes the design limit. Twenty-four access links at 10Gb represent 240Gb/s in one direction. Four 25Gb links provide 100Gb/s before any are reserved for another role. Those are calculated interface totals, not measured application throughput. A deployment sending every full-rate access stream upstream would need more capacity or a different distribution of sources and receivers; traffic staying within the switch changes that calculation.

The power limit is 30W per port

This exact model supplies PoE+ at up to 30W per copper port. The M4350 family's higher-power positioning does not make XSM4328CV a 60W or 90W switch. Its base PoE budget is 576W, expandable to 720W, while NETGEAR lists 576W as the redundant PoE budget.

That creates a concrete purchasing choice. Twenty-four allocations of 30W consume 720W, so the maximum expanded configuration can cover that arithmetic but the redundant budget cannot. If all those devices must remain powered after a supply failure, select a different power design or reduce the protected load. An extra supply and a fully protected endpoint population are not automatically the same thing.

AV profiles reduce repetitive work

The AV interface, IGMP Plus and included AVB support make the product appealing when a supported media workflow would otherwise require a long sequence of individual settings. A saved, reviewed configuration can shorten repeated room deployments and make the handover more consistent across technicians.

Profiles do not define where routing occurs, how separate clock domains interact, or how much traffic crosses an uplink. AVB support also should not be treated as blanket certification for every broadcast IP workflow. Match the endpoint system to the relevant protocol and firmware support, then retain the configuration needed to reproduce the installation. The practical benefit is fewer repeated decisions, provided the original decisions are correct.

Field evidence points to topology as a major risk

An engineer commissioning a large mixed M4350/M4500 AV network reported repeated spanning-tree changes and network disruption while much of the media traffic was still absent. The deployment used other M4350 models, so that report does not establish a fault in XSM4328CV. It does show why spare bandwidth alone cannot prove that a large media network is healthy.

Cartennas would use that evidence to shape acceptance: bring up the redundant links in controlled groups, confirm the intended forwarding paths and watch topology-change counters before loading the network with streams. Repeat the test after losing and restoring an uplink. A profile that makes the first endpoint easy should not conceal the behavior of the entire network during a fault.

The right upgrade from a small AV switch

This model makes sense when port count, faster copper or the 25Gb connection changes what the installation can carry. It is a weaker upgrade when all endpoints remain Gigabit and only a few require power. In that situation, the smaller switch may already provide the useful profile workflow, with a simpler power and cooling requirement.

The purchasing case should identify what the additional capacity enables: more simultaneous streams across a particular path, fewer separate switches, or a supported endpoint that cannot fit the old port speed. That turns a family upgrade into a measurable operational improvement.
