Řízený switch Trendnet TI-PG541i

TRENDnet TI-PG541i is a 6-port hardened industrial Gigabit PoE+ Layer 2 managed DIN-rail switch with four Gigabit PoE+ ports, one Gigabit copper port and one Gigabit SFP slot. The switch provides a 120 W PoE budget, an IP30 metal enclosure, dual redundant power inputs and is designed to operate in harsh environments with wide temperature tolerance and protection against vibration, shock, ESD/EMI and surge.

Advantages

The TI-PG541i delivers full PoE+ power per port while offering Layer 2 management features such as per-port PoE control, VLANs, multicast snooping and QoS for predictable traffic handling. Its hardened IP30 metal housing, integrated DIN-rail mount and compliance with industrial shock and EMC standards ensure reliable operation in demanding installations. Redundant power inputs and an alarm relay increase fault tolerance and simplify monitoring.

How to use

Mount the TI-PG541i on a DIN rail using the integrated hardware and connect primary and redundant DC power inputs according to the installation guide. Connect PoE devices to ports 1–4 and additional network devices to the remaining Gigabit port or SFP slot. Configure Layer 2 settings, PoE per-port behavior, VLANs, QoS and monitoring options via the web GUI, CLI or SNMP to integrate the switch into your network and tailor power delivery and traffic policies.

Recommendations

For reliable deployment in industrial or outdoor-adjacent sites, use properly rated power sources and grounding, enable redundant power configuration, and configure PoE scheduling and PD alive checks to prevent unexpected power interruptions to connected devices.
