48-port Gigabit unmanaged switch

The Netgear GS748-100NAS is a 48-port Gigabit Ethernet switch built for small offices and workgroups that need plug-and-play wired connectivity. It operates at Layer 2 only and requires no configuration software or licensing. The metal enclosure supports both rack-mount and desktop placement. Power draw is 8.81 W under typical load.

Silent fanless install with fixed ports

The unit ships fully assembled with internal fanless cooling, so there are no moving parts to fail or rattle in quiet environments. All 48 RJ-45 ports are fixed on the front panel; there are no modular uplinks or SFP cages to populate. Auto-negotiation handles 10, 100 and 1000 Mbps links automatically, and jumbo frames up to 9216 bytes pass through without setup. The only common install issue is cable congestion when all 48 ports are patched in a shallow rack.

Check rack depth and power budget first

Before ordering, verify that your rack or shelf provides enough depth for the enclosure and that the front cable bend radius will not exceed the patch-panel clearance. Confirm the site has a standard AC outlet for the internal power supply; no PoE budget exists for phones or cameras. Ensure your network design does not require VLANs, link aggregation or any Layer 3 routing, because the switch is strictly unmanaged and non-stackable.

Questions about this item

How can I confirm the GS748-100NAS is operating correctly after connecting 48 devices?

All 48 RJ-45 port LEDs should light solid or blink green at 10/100/1000 Mbps; the unit draws about 8.81 W when fully loaded and runs silently without fans.

What ships with the GS748-100NAS and what must I source separately?

The box contains the unmanaged Layer 2 switch, a rack-mount kit for standard cabinets and a power cord; you must supply Cat 5e or better twisted-pair patch cables for each of the 48 ports.

Which capacity should I choose between the 48-port GS748-100NAS and a smaller model?

Select the GS748-100NAS when you need 48 simultaneous Gigabit RJ-45 connections in a single 1U enclosure; smaller models provide fewer ports and would require multiple units to reach the same density.
