PRODUCT DESCRIPTION
NETGEAR M4300-48XF 48-Port 10G SFP+ Stackable L3 Managed Switch, 2x Shared 10GBASE-T (XSM4348FS-100AJS) - Limited Lifetime Local Warranty
48 Ports of 10G Fibre
The M4300-48XF provides 48 x SFP+ ports (1G / 10G) plus 2 shared 10GBASE-T RJ45 ports (100M / 1G / 10G), on a 960 Gbps non-blocking switching fabric with latency under 0.9µs (10G SFP+) — built for fibre-heavy cores and aggregation.
Redundant Modular Power
The full-width 1U chassis has two modular PSU bays. One APS250W is included; add a second APS250W for 1+1 redundant power.
Stacking with Non-Stop Forwarding
Up to eight M4300 switches can be aggregated into a single virtual chassis, and 10G models stack seamlessly with 1G models. There are no dedicated stacking ports: any 10G port (copper or fibre, RJ45, SFP+ or DAC) can be used. Non-Stop Forwarding (NSF) gives hitless failover from the management unit to the redundant management unit, and the stack is seen by the rest of the network as a single bridge or router.
Zero-Touch Pro AV Multicast
NETGEAR IGMP Plus provides automatic Layer 2 multicast out of the box: IGMP Snooping, IGMP Fast Leave and IGMP Querier are already enabled, giving zero-touch AV-over-IP with pre-configured L2 multicast (SDVoE-ready).
Layer 3 Routing with No Licence
The entire M4300 feature set, including L2 switching with IGMP Plus and L3 routing (static, RIP, OSPF, VRRP, PIM-SSM and policy-based routing) plus PTPv2, is available without a licence. Manage it through the industry-standard CLI, the NETGEAR web GUI or SNMP, with sFlow and RSPAN for visibility.

No. The 2 10GBASE-T ports are shared with SFP+ ports, so the switch provides 48 active 10G ports in total.
Can I add a redundant power supply?
Yes. There are two modular PSU bays; add a second APS250W for 1+1 redundancy.
Do I need a licence for Layer 3 routing?
No. Static, RIP, OSPF, VRRP, PIM-SSM and policy-based routing are included without a licence.
Can it stack with other M4300 switches?
Yes. Up to 8 M4300 switches, 1G and 10G models mixed, can form one stack using any 10G port, with NSF hitless failover.
What warranty do I get?
Limited lifetime local warranty in Singapore, supplied by SourceIT with a GST invoice.
