24x PoE+, 4x SFP, 96 Gbps, 71.4 Mpps, QoS, VLAN, SNMP, 802.1X, RSTP, MSTP
TRENDnet’s 48-Port Gigabit PoE+ Managed Layer 2 Switch with 4 shared SFP slots, model TL2-PG484, has 24 x Gigabit PoE+ ports, 24 x Gigabit ports, and 4 x shared SFP slots, a console port, a PoE Power budget of 370 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 370 W PoE power budget supplies PoE+ (up to 30 W) to ports 1-24 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 24 x Gigabit PoE+ ports, 24 x Gigabit ports, 4 x shared SFP slots, a console port, and includes rackmount brackets.

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.
