TRENDnet's 28-Port Gigabit Web Smart PoE+ Switch, model TPE-2840WS, offers 4 x Gigabit PoE+ ports (Ports 1-4 802.3at), 20 x Gigabit PoE ports (Ports 5-24 802.3af), 4 x SFP slots, and a PoE Power budget of 185 Watts. This IPv6 ready switch offers advanced traffic management, troubleshooting, access control, energy saving GREENnet, and monitoring features at a reduced cost.

The TRENDnet network switch has a reset button on the left side, followed by a PoE/connectivity LED toggle. The middle section features Gigabit PoE+ ports, with Gigabit PoE ports adjacent to them. SFP slots and a smart fan are on the right side. Included mounting brackets are shown separately on the right.

Hardware Design

Provides 4 x Gigabit PoE+ ports (Ports 1-4 802.3at), 20 x Gigabit PoE ports (Ports 5-24 802.3af), 4 x SFP slots, a PoE Power budget of 185 Watts, 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.
