Extreme ExtremeSwitching X870-G2 Switches - Refurbished, Used, and New
Extreme ExtremeSwitching X870-G2 switches deliver the speed and scale needed for next-generation enterprise and data center networks. Designed for high-performance backbones, these switches provide dense 100G and 400G connectivity in a compact 1RU platform, supporting demanding workloads such as cloud services, virtualization, and AI-driven applications.
The X870-G2 series includes models with up to 32 QSFP28 ports for 100G or 40G, with support for breakout configurations to 4x25G or 4x10G channels. Select models also support QSFP-DD modules, enabling 400G uplinks for environments preparing for future expansion. This flexibility makes the X870-G2 ideal for building leaf-spine architectures that require non-blocking throughput and low latency.
Running on ExtremeXOS, the X870-G2 delivers advanced Layer 2 and Layer 3 features, including IPv4/IPv6 routing, ACL-based security, and Quality of Service to prioritize critical applications. SummitStack-V and SummitStack-V160 stacking technologies allow multiple switches to operate as one logical system, simplifying administration while improving resiliency. Hot-swappable power supplies and fans, along with variable airflow options, ensure continuous operation in mission-critical deployments.
The ExtremeSwitching X870-G2 family is purpose-built for enterprises and service providers seeking dense, scalable 100G and 400G switching with proven reliability.
