8-Port Gigabit and 4-SFP Managed PoE Switch
Description
The Townet TW-SB8-POE managed PoE switch is designed to ensure reliable connectivity in industrial settings. It features 8 Gigabit RJ45 ports and 4 SFP slots, with 4 Mbit buffers to support up to 4K video transmission. The switching capacity is 24 Gbps with up to 4K MAC addresses.
The PoE ports offer flexible power supply: the first two support 24V passive or 48V active PoE (IEEE 802.3af/at) up to 30W, while the others can reach 60W with IEEE 802.3bt standard. The total PoE budget is 384 W, with redundant 37 57 V DC power supply up to 8 A.
The device integrates advanced network features such as up to 4K VLANs, QoS, LACP, RSTP/MSTP, IGMP Snooping, L2-L4 ACLs, 802.1X authentication, and Fast Ring protocol, which ensures self-recovery in less than 20 ms on cascaded networks of up to 30 switches. Management is via web interface, SNMP, CLI console, with I/O alarms, and temperature sensor. Robustness is ensured by industrial-grade surge protection up to 8 kV.
