What is the switching performance?

The switch delivers 48 Gbps switching capacity and 35.7 million pps throughput with non-blocking architecture. It handles 8K MAC addresses, 32 routing entries for static IPv4/IPv6, and jumbo frames up to 9216 bytes for efficient large data transfers.

Does it support PoE and what power output?

Yes, it provides IEEE 802.3at PoE+ on 24 ports with up to 370W total PoE budget from external power supply. Idle power is around 55-78W, max rating 920W including 740W PoE, suitable for powering IP phones, APs, and cameras.

What management features are available?

Management includes Secure Web GUI, SNMPv1/v2c/v3, RMON, complete session logging, multiple config files, and dual flash images. Protocols supported: IP multicast snooping, IGMP, Ethernet OAM, enabling comprehensive monitoring and IRF stacking.

Is stacking supported and how?

Yes, via Intelligent Resilient Framework (IRF) technology, treating multiple switches as one logical device for higher resilience and performance. Uses 2 slots for high-bandwidth stacking up to 10GbE, reducing complexity in enterprise stacks.

What are the physical dimensions and form factor?

1U rack-mountable chassis measures 43.6 x 44 x 30 cm (or up to 42 cm depth variant), weighing around 7kg. Operates in 0-45°C temperature and 10-90% humidity, ideal for standard data center racks.
