What is the PoE budget and power specs?

Provides 370W PoE power from a 487W maximum rating internal 80 PLUS Silver PSU, with 46W idle consumption on 100-240 VAC input. Supports IEEE 802.3at PoE+ up to 30W per port, ideal for powering multiple endpoints without separate power infrastructure.

What are the performance metrics?

Delivers 95.2 Mpps throughput and 128 Gbps switching capacity with a 16000-entry MAC table. Powered by 1 x ARM 625 MHz processor, 512 MB SDRAM, and 1 GB flash, it ensures low-latency Gigabit Ethernet handling for enterprise access.

Does it support Layer 3 routing?

Yes, as a Layer 3 switch with RIP and static IP routing, supporting 2048 IPv4 entries and 256 IPv6 entries. Additional features include IPv6 support, ACLs, and SDN OpenFlow for advanced network segmentation and management.

What management protocols are available?

Supports SNMP 1/2c/3, RMON 1, Telnet, TFTP, CLI for remote management, plus RADIUS authentication. These enable comprehensive monitoring, configuration, and security for IT teams in stackable deployments up to four switches.

What are the physical and environmental specs?

1U rack-mountable form factor measures 17.40 x 13.20 x 1.80 inches, weighs 11.60 lbs. Operates in 32°F to 131°F (0°C to 55°C) and 15-95% non-condensing humidity, suitable for standard enterprise racks and data closets.
