Product overview

The Extreme Networks SLX 9140-48V-AC-R is a high-performance 1U rackmount Layer 3 managed Ethernet switch designed for datacenter top-of-rack deployments. It features 48x 25/10/1 GbE SFP28 ports and 6x 100/40 GbE QSFP28 ports, delivering 1.8 Tbps switching bandwidth in each direction for a total of 3.6 Tbps full duplex. Forwarding capacity reaches 1.2 Bpps at Layer 2 and 600 Mpps at Layer 3 with line-rate performance. The switch supports up to 96,000 MAC addresses, 4,096 VLANs, 80,000 routes, and 2,000 ACLs in hardware. Dual redundant 650W AC power supplies ensure high availability, with typical consumption at 182W and maximum at 489W. Back-to-front airflow maintains optimal cooling in dense racks, operating from -5°C to 45°C. Five field-replaceable fans and MTBF of 324,414 hours enhance reliability. Management includes RJ-45 Ethernet, RJ45/USB-C console, and USB storage ports. IEEE standards like 802.1Q VLAN, 802.3ad LACP, and 802.1p CoS enable robust networking.
