Is configuration required for setup?

No, it's an unmanaged switch with plug-and-play installation. Autosensing and auto MDI/MDIX on all ports eliminate the need for software configuration, ideal for quick SMB deployments.

What are the power and environmental specs?

Uses external 100-240 VAC adapter with 3.4W consumption. Operates at 0° to 40°C (32° to 105°F), 10% to 90% non-condensing humidity; fanless design ensures silent, reliable performance in office settings.

What Ethernet standards are supported?

Compliant with IEEE 802.3, 802.3u, 802.3ab for 10/100/1000BASE-T. Supports full-duplex, jumbo frames, and IEEE 802.1p prioritization for optimal Gigabit performance and legacy compatibility.

What are the dimensions and weight?

Measures 117.0 mm (4.6 in) wide, 30.5 mm (1.2 in) high, depth not specified; weighs 240 g (8.5 oz). Compact desktop/rack-mountable form suits small office expansions.

What compliance certifications does it hold?

Safety: UL 60950-1, EN 60950-1, CSA 22.2 60950-1, IEC 60950-1; Emissions: FCC Class B. Certified for home/office use, ensuring regulatory compliance for enterprise procurement.
