Features
Layer 3 All-Optical 10G Core & Aggregation Switch RG-S6120-20XS4VS2QXS
Recommended aggregation switch for large-sized networks, or core switch for small and medium-sized networks. With 20 x 1GE/2.5GE/10GE SFP+ ports and 4 x 10GE/25GE SFP28 ports, the switch provides flexible access capabilities. The 2 x 40GE QSFP+ uplink ports deliver high-speed uplink connectivity, fully satisfying the requirements of high-performance networks.
VSU Virtualization, Flexible Networking and High Performance
- Millisecond Failover
Connected by an aggregate link, the VSU virtual system and peripherals switch links in milliseconds to ensure service continuity in case of a failure.
- High Scalability
VSU virtualization technology is supported to increase bandwidth through link aggregation, which greatly improves forwarding capabilities of the switch.
- Simplified Networking
Multiple physical switches can be virtualized into one logical unit to simplify network configuration and architecture, eliminating loops, and improving reliability.
Hardware Redundancy, Guaranteed Service Continuity and Network Connectivity
- Hot-Swappable Power Modules + Intelligent Fan Modules
Power modules can be replaced without affecting device operation. Intelligent fan speed regulation is supported for efficient cooling, providing dual protection for the network.
- Hardware-Level Boot Redundancy
Two Flash chips are used to store the system boot program for hardware-level boot redundancy, avoiding device failure caused by a failed Flash chip.
- Optical Port Fault Isolation
The innovative isolated chip design ensures that short-circuit current cannot reach the power supply chip directly. Failure of one optical module will not affect the normal operation of other optical ports, thus effectively ensuring service stability.
Network Security Policies and Real-Time Monitoring, Delivering Enhanced Network Robustness
- CPP
CPP protects the CPU from data attacks to ensure CPU stability under high usage, achieving significant improvement in the device’s security performance.
- NFPP
NFPP protects CPU from high load damage to guarantee device management and operation, thus improving network security and stability.
Ruijie Unified Networking Central (RG-UNC) Visualized Management, Automated and Effortless Operations
- RG-UNC, a unified visual management platform, supports real-time monitoring of key devices and links, fine-grained alarms, centralized configuration backup and recovery, network-wide management, plug-and-play, and rapid deployment, enhancing O&M efficiency.
RG-UNC Unified Networking Central – Simplified Management, Automated and Effortless Operations
- Unified platform management, real-time monitoring of network status, comprehensive insight into the user experience chain, intelligent analysis and diagnosis, and comprehensive protection of the business experience.
- Supports end-to-end operation and maintenance of optical links, and makes optical networks visible, manageable, and controllable.
