Řízený L2 Gigabit Ethernet switch Trendnet TI-PG102I

The TRENDnet TI-PG102I is a Managed L2 Gigabit Ethernet switch with eight Gigabit PoE+ RJ-45 ports and two Gigabit SFP slots. It provides a 240W PoE budget (up to 30W per port), a switching capacity of 20 Gbps, and a hardened IP30 metal enclosure with DIN-rail mounting for industrial installations. The switch operates over a wide temperature range (-40° to 75° C) and includes redundant power inputs, alarm relay output, and diagnostic monitoring features suitable for SMB and industrial networks.

Advantages

The TI-PG102I delivers centralized power distribution via PoE+ with per-port controls (enable/disable, priority, PD alive check, scheduling) and supports flexible network integration through managed L2 features such as VLANs, QoS, IGMP snooping, link aggregation and access control lists. Industrial-grade construction (IP30 metal case, shock and vibration resistance) and wide operating temperature make it suitable for harsh environments, while SNMP, RMON and syslog support enable remote monitoring and troubleshooting.

Suitable for

• Powering and connecting IP cameras and access points with PoE+ in industrial or commercial sites
• Small and medium business networks requiring managed L2 features (VLAN, QoS, ACL)
• Fiber uplinks or long-distance links using 100Base-FX / 1000Base-FX SFP modules
• Environments requiring DIN-rail mounting and wide temperature operation

How to use

Mount the TI-PG102I on a DIN rail and connect DC power to the redundant power inputs (use compatible TRENDnet power supplies). Connect PoE devices to the RJ-45 ports and install SFP fiber modules in the SFP slots for uplinks if needed. Access the switch management interface via web GUI, CLI or SNMP to configure VLANs, PoE policies, QoS, ACLs and monitoring options. Use SNMP, syslog or RMON for remote monitoring and enable alarm relay to notify on main or redundant power failure.

Recommendations

For stable PoE operation, calculate total PD power requirements to ensure the 240W budget is not exceeded; assign power priority to critical devices and enable PD alive check and scheduling to manage power during peak loads. Use compatible SFP modules for required fiber speeds and verify environmental ratings when installing in extreme temperature or high-vibration locations.
