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.

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 network switch features multiple ports and indicators, including a reset button, LED indicators, Gigabit PoE+ ports, Gigabit ports, shared Gigabit ports, and shared SFP slots. The back of the switch has a console port and a power port, with labels that clearly identify each component, making it easy to understand the functionality and connectivity options.

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.
