STARTECH IESC1G50UP 5-port Gigabit PoE+ network switch 30W

Industrial 5-port Gigabit PoE+ switch

The StarTech.com IESC1G50UP is an unmanaged desktop switch with five RJ45 ports that each deliver up to 30W of PoE+ power. It targets installers who need to run IP cameras or wireless access points in harsh environments without a separate power supply. The hardened enclosure operates from -40°C to 75°C and mounts on DIN rail or wall brackets. Redundant terminal-block inputs keep the link alive if one feed fails.

Sustained-load behaviour

Each port can supply the full 30W continuously while the switch passes 1000Mbps traffic, and the total PoE budget reaches 200W across all five ports. IEEE 802.3x flow control and back-pressure prevent frame loss when buffers fill during prolonged bursts. The 9KB jumbo-frame limit reduces per-packet overhead on long video streams. Maximum system draw is 126W, so the redundant inputs must be sized accordingly.

Practical limits of the Gigabit and PoE+ interfaces

Copper links are restricted to 100 metres per segment at 1000BASE-T, and PoE+ power drops off toward that distance. The 30W per-port ceiling is fixed by the IEEE 802.3at standard; devices needing more must use a midspan injector or a higher-standard switch. Unmanaged operation means no VLANs, QoS or remote monitoring — configuration is purely plug-and-play. Storage temperature extends to 85°C for cold-spare staging.
