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.

A cloud labeled Network connects to five boxes labeled VLAN, IGMP, QoS, and SNMP, all of which are linked to a network switch below. The switch features several Ethernet ports, illustrating its capability to manage multiple network functions.

Integration Flexibility

Managed features include access control lists, VLAN, IGMP snooping, QoS, RMON, SNMP trap and syslog for monitoring and flexible network integration.

The TRENDnet Layer 2 Managed PoE Switch model TL2-PG284 has a front panel labeled with various components. On the left side are a reset button and a PoE/connectivity LED toggle, next to a console port. There are three sections of ports: the first and second sections contain gigabit PoE+ ports, and the third section contains SFP slots, each clearly marked and labeled for easy identification.

Hardware Design

Provides 20 x Gigabit PoE ports, 4 x Gigabit PoE+ ports, 4 x 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.
