Διαχειριζόμενος διακόπτης Trendnet TI-PG1284i

The TRENDnet TI-PG1284i is a hardened, managed Layer 2+ Gigabit Ethernet switch with eight Gigabit PoE+ ports, four Gigabit SFP slots and a total PoE budget of 240 W. Housed in an IP30-rated metal enclosure with integrated DIN-rail mounting, the switch is designed for harsh industrial environments and supports wide operating temperatures from -40 to 75 °C. L2+ management features include PoE port control, 802.1Q / Q-in-Q VLAN, multicast support, spanning tree, link aggregation, QoS, IPv4/IPv6 static routing, ACLs and 802.1X for flexible network integration.

Advantages

The TI-PG1284i combines industrial-grade mechanical protection and wide-temperature operation with full PoE+ power per port and advanced L2+ management. It provides fault tolerance via dual redundant power inputs and an alarm relay, detailed per-port PoE controls, extensive traffic management (VLANs, IGMP snooping, QoS, link aggregation, spanning tree and ring/ERPS protection), and comprehensive monitoring through SNMP, RMON and syslog. The switch’s 24 Gbps switching capacity, SFP uplink slots and console port enable flexible deployment and out-of-band management.

Suitable for

• Industrial automation and control networks requiring hardened equipment
• Surveillance systems and IP cameras that need PoE+ power and centralized management
• Transportation, utilities or outdoor cabinets with wide temperature and vibration requirements
• Small to medium enterprise edge aggregation with fiber uplinks via SFP

How to use

Mount the TI-PG1284i on a DIN rail using the integrated mounting hardware and connect AC or DC power to the primary and redundant power inputs as required. Connect network devices to the Gigabit PoE+ RJ‑45 ports and uplink fibers to the SFP slots. Use the console port or web/CLI management to configure PoE settings, VLANs, QoS, static routes and access controls. Enable alarm relay and power redundancy features to monitor input power status.

Recommendations

For reliable operation in industrial settings, ensure the switch is installed in a properly grounded cabinet, keep SFP modules and cabling within the specified temperature ranges, and configure power priority and PD alive check for critical PoE devices. Use SNMP or syslog monitoring to track status and alarm outputs for power-failure notifications.
