Is this a managed switch and what layer does it operate at?

Yes, it is a fully Layer 4 managed Ethernet switch supporting static Layer 3 routing, IPv6, ACLs, and IRF stacking. Management via console port or HP IMC enables advanced features like flow control and jumbo frames up to 9216 bytes, ideal for enterprise traffic optimization and security.

What is the form factor and physical size?

Rackmountable 1U design with dimensions approximately 440mm depth, 300mm width, 43.6mm height, weighing 4.5 kg. Fits standard 19-inch racks, making it suitable for data centers and wiring closets. Internal PSU supports global AC 100-240V input with low 62W typical consumption.

What performance specs does it offer?

Delivers 48 Gbps switching capacity with nonblocking architecture, 16K MAC address table, and 32 routing entries. Supports Gigabit speeds, jumbo frames, and IEEE 802.3x flow control for wirespeed performance in demanding environments. Throughput handles up to 35.7 million pps.

Does it support stacking or expansion?

Yes, Intelligent Resilient Framework (IRF) enables stacking multiple switches as one logical device for enhanced resiliency. 4x shared SFP ports and 2 interface slots (model variant) allow expansion. High-bandwidth stacking up to 96 Gbps full duplex via CX4.

What are the environmental operating conditions?

Operates from 0 to 45°C temperature and 10-90% relative humidity. AC input 100-240V at 50-60 Hz with DC-in jack. Designed for reliable performance in enterprise IT environments, with low power draw of 62W typical.
