3-Gigabit-Modular-Slots Chassis L2 + Managed Switch with 
12-48V DC Redundant Power Supply socket

  • Maximum 24xGigabit T / SFP connectivety
  • Advanced SNMP functionality for L2plus
  • Supports IGMP v1, v2, v3**


    Lantech LGS-2300-RPS is a full SNMP L2+ / Web managed switch that suits FTTX Ethernet network, Campus network, Surveillance control room network in aggregation point. The RPS (redundant power supply) can secure the switch from downtime or to be used in Telco environment that requests -48V power input.

    The unique features of LGS-2300-RPS are ACL 256 List*, IP address security, Mac address filtering, Static Mac filtering for big network security. The bandwidth control and rate shaping are ideal for ISP or Campus administration to allocate appropriate bandwidth within big network. The DHCP server, client function can manually configure a specific IP address, or direct the device to obtain an IP address from the network. It also supports Quality of Service (QoS), which adjusts the network traffic priority, for example, video and voice packets as high priority , in which it supports 8 priority queues with Cos (Class of Service) standard. The Internet Group Management Protocol (IGMP Query & Snooping) manages the multicast packet application in the network without congest the network, for on-line study or video conference applications. The SNTP and SMTP functions can immediately alert up to 10 email accounts for any events of the switch.email accounts for any events of the switch.

    Three (3) Modular Slots designed in 1 u compact size provides the maximum resilience link in mix of Fiber and Copper cables where meets every network demand.
