What is the switching capacity and performance?

Switching capacity is 104 Gbps with throughput up to 77.4 Mpps and 1000 Mb latency under 3 µs. It features a 1 MB packet buffer, 8K MAC table, and 32 IPv4 routing entries, enabling full wire-speed L4 switching for demanding enterprise traffic.

Is it rack-mountable and what are the dimensions?

Yes, it's a rack-mountable 1U switch measuring 17.3(w) x 10.24(d) x 1.72(h) inches (43.94 x 26.01 x 4.37 cm), weighing 11.02 lb (5 kg). It fits standard 19-inch EIA racks, ideal for data centers.

What memory and processor specs are included?

128 MB flash storage, 128 MB SDRAM, and 1 MB packet buffer size. This hardware supports stable operation, jumbo frames up to 10k bytes, and features like flow control for congestion management in high-traffic scenarios.

What advanced features does it support?

Layer 3 managed with Ethernet OAM (IEEE 802.3ah), QoS policies, redundancy, security controls, and jumbo packet support. It provides diversified management via IMC and high reliability for access/distribution layers.

What is the operating environment range?

Operates from 32°F to 113°F (0°C to 45°C) with 100-240 VAC power input. Maximum heat dissipation is 189 BTU/hr, making it suitable for standard enterprise IT closets and data centers without special cooling.
