Accessory

RPS-300W-B (GWN7813P)
Redundant Power Supply
The redundant power supply increases the stability of switch working. It helps ensure uninterrupted operation and protection against device power supply failures by providing seamless failover for switch. RPS-300W-B provides PoE capability with maximum output 240W.
Product Highlights
High Performance with Maximum Network Capacity and Control
Grandstream's GWN7820 Series network switches are ideal for enterprises and medium-to-large businesses that require high-performance networks with maximum network capacity and control.
- Supports advanced VLAN for flexible and sophisticated traffic segmentation, advanced QoS for prioritization of network traffic, IGMP/MLD Snooping for network performance optimization, and comprehensive security capabilities against potential attacks
- The PoE models provide smart dynamic PoE output to power IP phones, IP cameras, Wi-Fi access points, and other PoE endpoints. GWN7820 series can be managed in a number of ways, including the local Web user interface of the GWN7820 series switch and CLI, the command-line interface. The series is also supported by GDMS and GWN Manager, Grandstream’s cloud and on-premise network management platform.
- The GWN7820 series are the best value enterprise-grade managed network switches for medium-to-large businesses
