48-port 10 Gbps managed switch

The Netgear ProSafe XSM4348S-100NES provides 24 RJ45 ports and 24 SFP+ ports, each running at 10 Gbps with 1 Gbps backward compatibility. It targets mid-size enterprises that need a single stackable chassis for copper and fibre uplinks.

960 Gbps non-blocking fabric under load

All 48 ports operate independently on a 960 Gbps switching fabric so sustained line-rate traffic on every port does not create internal contention. Redundant modular power supplies and hitless failover keep the stack forwarding during a master failure.

Replaces mixed 1 Gbps and 10 Gbps stacks

The switch consolidates separate copper and fibre stacks into one virtual chassis that supports OpenFlow 1.3 for SDN integration. It is not for sites that require Power over Ethernet or need more than 48 ports in a single unit.

Questions about this item

How much heat and noise does the XSM4348S-100NES produce when all 48 ports run at 10 Gbps continuously?

The switch uses dual redundant modular power supplies and a non-blocking 960 Gbps fabric designed for continuous line-rate operation in rack environments.

Which transceivers or cables must I already own to use the 24 SFP+ ports on this switch?

The 24 SFP+ sockets accept standard 10GBASE-X modules or direct-attach cables; rubber caps are included to protect unused ports.

Can the M4300 stack with my existing 1 Gbps switches without losing performance?

Yes, 10 Gigabit M4300 models stack with 1 Gigabit models using any 10G port media, enabling line-rate spine-and-leaf topologies with hitless failover.
