Applications

Ideal for applications requiring a large number of PoE ports. Provide efficient operation, facilitate network management and improve security. A high-quality ARM Cortex-A9 processor clocked at 400MHz and 2GB of 800MHz DDR3 memory ensure stable and fast switch operation. For additional performance, the device has a 16Mbit packet buffer for efficient management of large amounts of data.

Advanced features

The GS2048PS4 switch is extremely flexible in terms of configuration. It supports multiple network management protocols, such as STP/RSTP/MSTP, RIP, OSPF, VRRP, IGMP SNOOPING and more. With the VLAN function, the switch allows you to create up to 4K virtual local area networks, which allows you to effectively manage network traffic and enhance network security. Equipped with advanced features such as IEEE802.3x flow control, surge protection and auto-sensing technology, which provides up to 90W of power to PoE++ 802.3bt devices.

Management Features

The GS2048PS4 switch supports a range of network management functions, including VLAN, QoS, IGMP Snooping, Link Aggregation, STP/RSTP/MSTP, access control and network diagnostics. This allows for efficient and flexible network management. In terms of security, the GS2048PS4 switch offers advanced features such as ACLs (Access Control Lists), WEB/Telnet password protection and CPU self-protection. In addition, it supports QoS (Quality of Service) functions to control and prioritize different types of network traffic.

Support for PoE++

The GS2048PS4 switch supports the PoE++ (IEEE 802.3bt) standard on ports 1 to 4, enabling it to deliver up to 60W of power per port. The remaining ports support the PoE+ (IEEE 802.3at) standard with delivery of up to 30W of power per port. For the convenience of network administration, the GS2048PS4 switch offers various management options, including CLI (Commend Line Interface), configuration via console port, management via Telnet and Web, as well as SNMP. These features make it easy and convenient to manage a network, regardless of its size or complexity.
