Is this switch managed or unmanaged?

This is an unmanaged network switch, requiring no configuration or software setup. It operates plug-and-play, ideal for small offices needing quick expansion. Supports IEEE 802.3 standards for reliable Layer 2 switching.

What is the maximum speed per port?

Each port auto-senses 10/100 Mbps, with full-duplex mode providing up to 200 Mbps bidirectional throughput. This doubles effective bandwidth for applications like file transfers and internet access in workgroups.

Does it support legacy equipment?

Yes, ports auto-negotiate between 10BASE-T and 100BASE-TX, ensuring compatibility with older 10 Mbps devices alongside modern Fast Ethernet gear. Auto MDI/MDIX further simplifies integration without special cables.

What are the physical dimensions and power requirements?

Dimensions: 220 mm width, 24.2 mm height, 135.4 mm depth; weight 480 g. Power consumption is 3 Watts via internal supply, operating in 0-95% non-condensing humidity for reliable office use.

What LEDs are available for monitoring?

Front-panel LEDs indicate power, activity, connection speed, and duplex status per port. This provides at-a-glance network diagnostics without technical tools, aiding quick troubleshooting in SMB environments.
