What ports does the Fujitsu XG2000R support?

It features 20 x 10GbE XFP ports (10 Gigabit Small Form Factor Pluggable), enabling high-speed fiber or copper connections. These support cut-through switching for ultra-low latency in enterprise 10G networks, as per Fujitsu datasheet and eBay listings.

What is the switching performance?

Switching capacity is 400 Gbps with 112 Mpps throughput and 512K MAC address table. Tolly benchmarks confirm zero-loss line-rate in 20-port full-mesh for frames 64-16,128 bytes, ideal for data center cores.

How low is the latency?

Ultra-low cut-through latency ranges 339-359 ns (average 341 ns) across frame sizes, 363 ns for Internet mix, including XFP transceiver. ServeTheHome and Tolly reports highlight its suitability for latency-critical apps.

What management options are available?

Includes out-of-band port, Web-based GUI, CLI, SNMP v1/v2c/v3, Telnet, SSH, HTTP/HTTPS. These enable comprehensive monitoring and configuration for enterprise IT teams, per Fujitsu datasheet.

What are the physical and power specs?

2U rackmount (17.6 kg, 3.5x19x24 inches), steel chassis with front-to-back airflow. Dual redundant hot-swap AC supplies, 1200W typical, operating 0-40°C, 10-90% humidity, <65 dB noise.

Is it suitable for data centers?

Yes, designed for 10GbE core networks with 400Gbps non-blocking, zero-loss performance, and redundancies. Compliance: FCC Class A, CE Mark, RoHS, supports high-density server interconnects reliably.
