Cudy GS5048S4 48-GbE 4-SFP+ L3 Managed Gigabit Switch

Cudy GS5048S4 48-GbE 4-SFP+ Layer 3 Managed Gigabit Switch is a sure thing for large networks that need quick data, longer control, and powerful security. It offers industry-standard support like IEEE 802.1d, 802.1w, 802.1s, 802.1p, 802.3, 802.3u, 802.3x, 802.3z, 802.3ab, and 802.3ae to provide wide compatibility and smooth operation on all platforms. The switch has 48 Gigabit Ethernet ports and 4 10G SFP+ uplink slots, handling large traffic flows and providing distant connectivity through fiber. L3 management functions include DHCP Server support, QoS for priority control of traffic, ACL for controlling access to traffic, SNMP v1/v2/v3, and IGMP Snooping v1/v2 for multicast management.

The switch delivers high Layer 2 and Layer 3 performance. STP, RSTP, MSTP, and ERPS are supported to offer better loop protection and network stability. Loop detection, self-healing, and remote loopback monitoring of 802.3ah OAM allow customers to easily identify and fix issues. Support for IPv4 and IPv6, and routing protocols RIP and OSPF, prepares it for the demands of modern networks. Advanced VLAN features include multiple VLAN partitioning, MAC VLAN, Protocol VLAN, and Private VLAN for traffic security and isolation. Network protection includes IP + MAC + VLAN + Port binding, DHCP Snooping, and IP source guard with DAI (Dynamic ARP Inspection).

With security in its design, the switch boasts strong surge protection: 4KV general, 2KV differential, and ESD protection that includes 8KV air discharge and 6KV contact discharge. These shield your network from power surges and static damage. Cudy GS5048S4 is a suitable choice for business networks, data centers, or campus setups demanding strong performance, full control, and safe operation.
