TRENDnet’s 28-Port Gigabit PoE+ Managed Layer 2 Switch with 4 SFP slots, model TL2-PG284, has 20 x Gigabit PoE ports, 4 x Gigabit PoE+ ports, 4 x shared SFP slots, a console port, a PoE Power budget of 185 watts, and an advanced Layer 2 management feature set. This IPv6 ready switch offers traffic management, troubleshooting, access control, and monitoring features.
Power over Ethernet
The 185 W PoE power budget supplies PoE+ (up to 30 W) to ports 1-4, PoE (up to 15.4 W) to ports 5-24, along with PD (powered device) auto classification and over current/short circuit protection.
Smart fans save energy and reduce operating noise by varying fan speed and usage based on real-time cooling needs.
Managed features include access control lists, VLAN, IGMP snooping, QoS, RMON, SNMP trap and syslog for monitoring and flexible network integration.
Provides 20 x Gigabit PoE ports, 4 x Gigabit PoE+ ports, 4 x SFP slots, a console port, and includes rackmount brackets.
