TRENDnet’s 28-Port Gigabit PoE+ Managed Layer 2 Switch with 4 SFP slots, model TL2-G284, 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
Smart fans save energy and reduce operating noise by varying fan speed and usage based on real-time cooling needs.
Integration Flexibility
Managed features include access control lists, VLAN, IGMP snooping, QoS, RMON, SNMP trap and syslog for monitoring and flexible network integration.

Hardware Design
Provides 20 x Gigabit PoE ports, 4 x Gigabit PoE+ ports, 4 x SFP slots, a console port, and includes rackmount brackets.
Smart Fan
Smart fan saves energy by varying fan speed and use based on cooling needs
IPv6 Ready
This switch supports IPv6 configuration and IPv6 neighbor discovery.
Traffic Management
A broad range of network configurations are supported by: 802.3ad link aggregation, Asymmetric VLAN, 802.1Q VLAN, Voice VLAN, Private VLAN, Bandwidth Controls, GVRP, IGMP v1-v3, 802.1p Class of Service (CoS), Spanning Tree (STP, RSTP, and MSTP), and QoS queue scheduling.
Troubleshooting
Real time traffic comparison charts, error group charts, and a convenient cable diagnostic test aid in rapid troubleshooting.
Access Controls
Features such as ACL, SSL, MAC / port filtering, Denial of Service controls, 802.1X, TACACS+, and RADIUS are compatible with layered network access controls.
Monitoring
RMON, SNMP, SNMP Trap, and Port Mirroring support administrator monitoring solutions.
