AT-9924T

10/100/100T x 24 ports Gigabit Ethernet Layer 3 switch with 4 combo SFP expansion slots

The 9924T is an advanced Gigabit Ethernet switch. The 9924T provides fine service provisioning granularity, high availability, advanced QoS and has the same modular power supplies used in the other 9900 series switches. The 9924T is best for networks that need SFP interface options. It offers extensive management features and advanced multicast routing options. Dual hot-swappable power supplies are supported and front-to-back airflow optimizes switch cooling.
