What are the key performance specifications?

It features a 36.6 Gbps switch fabric, up to 71.4 Mpps throughput, 1 MB packet buffer, and latency <10.2 µs for 100 Mbps FIFO 64-byte packets. Ethernet speeds cover 10/100 Mbps TX and 100/1000 Mbps T, ensuring high-performance Layer 2 switching for demanding networks.

What management interfaces are available?

Management is provided via CLI, web interface, and device software updates. Additional protocols include TACACS+, SSHv2, SNMPv3, and stacking for up to 16 switches under a single IP, simplifying administration in large enterprise environments.

What are the physical dimensions and mounting options?

Dimensions are 22.8 x 44.4 x 38.1 cm (9 x 17.5 x 15 in.), weighing 53.1 kg fully loaded. It mounts in EIA-standard 19-inch telco racks as 7U height with included hardware, or on horizontal surfaces, ideal for standard data center racks.

What are the environmental operating conditions?

Operating temperature is 32°F to 131°F (0°C to 55°C), humidity 15% to 95% relative at 104°F (40°C) non-condensing, storage -40°C to 70°C. This range supports deployment in diverse enterprise locations without special cooling requirements.

What power options does it support?

Uses an external power supply (100-127/200-240 VAC, 50/60 Hz) with optional hot-swappable redundant supply for high availability. This design minimizes downtime during maintenance or power events in critical infrastructure.
