Layer 3 24-Port 100/1000X SFP with 8-Port shared TP + 4-Port 10G SFP+ Stackable Managed Gigabit Switch with 36-75V DC Redundant Power, trunking stack up to 4 units


Core Routing Switch
With 24 Gigabit ports, 4 SFP+ fiber interfaces and Layer 3 IP/multicast routing capability, the XGS3-24242 provides high-performance solution for telecoms, network service providers and enterprises.

High-density and VRRP Backbone Routing Switch
With the built-in robust IPv4/IPv6 Layer 3 IP and multicast routing protocols, the XGS3-24242 ensures reliable routing between VLANs and network segments. The routing protocols can be applied by VLAN interface with up to 1K routing entries. The high-density routing interfaces provide expandability to meet the growing network’s needs. Moreover, with the hot VLAN feature – Q-in-Q (VLAN stacking) – supported, it allows the service providers to offer certain services such as Internet access on specific VLANs for specific customers and yet still provides other types of services for their other customers on other VLANs.

Data Center Security and QoS Switch
The XGS3-24242 performs 208 Gigabits per second non-blocking switch fabric, so it can easily provide a local, high bandwidth, and Gigabit Ethernet network for the backbone of your department. With the four built-in SFP+ ports, the XGS3-24242 provides the 10G uplink to the backbone network through 10G Ethernet LR/SR SFP+ modules. It further improves the network efficiency and protects the network clients by offering the security and QoS features.
