48-port 10G stackable switch

The Netgear ProSafe XSM4348CS-100NES is a managed Layer 4 switch built for mid-size enterprise cores and SMB aggregation. It delivers 48 RJ45 10GBase-T ports and four SFP+ expansion slots in a single rack unit. Stackable design allows mixed 1G and 10G models to form a single virtual chassis with non-stop forwarding.

Thermals noise and power

Maximum power draw is rated at 237.2 W under full load. The chassis operates from 0 to 50 °C with up to 90 % relative humidity, non-condensing. Storage tolerances extend to –20 to 70 °C and 95 % humidity. Dual redundant modular power supplies and full-width airflow keep temperatures stable without external cooling assumptions.

960 Gbps non-blocking fabric

A 960 Gbps switching fabric provides line-rate throughput across all 48 ports. The 128K MAC table and 12 KB jumbo frame support handle heavy multicast and storage traffic. Buyers who need Power over Ethernet must choose a different model, as this unit does not supply PoE.

Questions about this item

How do I install the Netgear XSM4348CS-100NES in a rack, and what step is often missed?

Mount the 1.73" high chassis using the included full-width rack kit, then insert the two modular power supplies — the step often missed is fitting both units for redundancy before powering on.

What maintenance or replacement will the Netgear XSM4348CS-100NES need later?

The two hot-swap power supplies are the only field-replaceable parts; fans are internal and not user-serviceable, so plan to replace a PSU if a fault LED lights.

What limit appears first on the Netgear XSM4348CS-100NES under sustained heavy load?

The 237.2 W maximum power draw and 50 °C operating ceiling are reached before the 960 Gbps fabric or 56 MB buffer saturate, so cooling and PSU capacity set the practical ceiling.
