What is the switching capacity and forwarding performance?

Switching capacity is 1.8 Tbps inbound + 1.8 Tbps outbound (3.6 Tbps total). Forwarding rates are 1.2 Bpps for L2 and 600 Mpps line-rate for L3, with 2.5 microseconds port-to-port latency, ideal for high-throughput ToR applications without oversubscription.

What power options does this DC model support?

Two internal redundant field-replaceable 650W DC PSUs with 40.8-60V input via C13 inlet. Typical power is 182W (10% traffic, low fans), maximum 489W (100% traffic, high fans), with 25A inrush and 14A max current, suited for DC-powered environments.

What scalability features are provided?

Supports up to 96,000 MAC addresses, 4,096 VLANs, 48,000 IPv4 unicast routes, 16,000 IPv6 routes, and 80,000 total routes in hardware, plus 2,000 ACLs. Jumbo frames up to 10,000 bytes and 8 QoS queues per port enable large-scale L2/L3 deployments.

What are the environmental specifications?

Operating temperature -5°C to 50°C (front-to-back), up to 55°C temporarily; storage -40°C to 70°C; humidity 5-95% non-condensing. Five FRU fans deliver 134 CFM front-to-back airflow, with 52 dBA noise at 25°C and MTBF of 324,414 hours.

Which protocols are supported for management and routing?

Includes SNMP v1/v2c/v3, SSH-2, SYSLOG, BGP-4, OSPF, OSPFv3, VRRP, IGMPv2, and BFD. These enable advanced automation, visibility, and dynamic routing in multi-tenant fabrics for cloud and enterprise datacenters.

Product overview

The Extreme Networks SLX 9140-48V (SKU: BR-SLX-9140-48V-DC-F) is a 1U rack-mountable Layer 2/3 managed Ethernet switch designed for datacenter top-of-rack deployments. It features 48 x 25/10/1 GbE SFP28 ports and 6 x 100/40 GbE QSFP28 ports, delivering 1.8 Tbps inbound and outbound switching capacity (3.6 Tbps total) with L2 forwarding at 1.2 Bpps and L3 at 600 Mpps line-rate. Low port-to-port latency of 2.5 microseconds supports high-performance workloads. The switch supports up to 96,000 MAC addresses, 4,096 VLANs, 48,000 IPv4 routes, and 80,000 total routes in hardware. Dual redundant 650W DC PSUs (40.8-60V input) ensure high availability, with typical power draw of 182W and max 489W. Front-to-back airflow with five field-replaceable fans maintains cooling in -5°C to 50°C environments. Management includes OOB Ethernet, serial console, and USB ports. Protocols like BGP, OSPF, VRRP enable advanced routing for scalable fabrics.
