48 Gigabit Ethernet ports and 4 10Gigabit SFP+ slots
Supports L3 management such as OSPF, RIP, QoS, VLAN, MSTP, multi-broadcast and port management
6KV surge, 6KV contact and 8KV air ESD protection
Working temperature range from -10℃ to 50℃

The LevelOne GTL-5291 offers powerful Layer3 Gigabit Ethernet switching with 52 ports, of which 48 are RJ45 10/100/1000BASE-T ports and another 4 are 10G SFP+ ports. It supports Layer3 management, such as OSPF, RIP, QoS, VLAN, MSTP, Multi-Brocast and Port Management. The switch is ideal for high-performance server aggregations, such as: B. in corporate data centers, where it can connect high-end or network-connected file servers via fiber optic ports. It can also be used as a backbone upgrade or to provide gigabit-to-the-desktop for power users. Packed with features, this switch is a cost-effective solution that provides continuous availability, enhanced security and advanced QoS to the edge network while being easy to manage.
