H3C S6520X-18C-SI 16x10G Access Switch
H3C S6520X-18C-SI Access/Aggregation Switch
Overview
The H3C S6520X-18C-SI is a compact 10G access/aggregation switch designed for campus access layers and SMB aggregation scenarios. It features 16 × 10GE SFP+ ports and 2 × expansion slots for uplink modules (10G/40G options depending on the module installed). With strong L2/L3 routing, IRF support, VXLAN capability, and carrier-grade reliability, it fits well for small aggregation or high-performance access scenarios.
Note: Power and fan modules sold separately.
Highlights
1. Compact 10G Access Aggregation
16 × 10GE SFP+ ports make it ideal for edge aggregation, SMB server access, or high-speed campus access.
2. Modular Uplink Flexibility
2 × uplink module slots support optional 10G/40G uplink modules, enabling flexible deployment planning.
3. Fabric-Ready Virtualization
VXLAN, EVPN (model/firmware dependent), and IRF stacking allow seamless integration into campus or enterprise fabrics.
4. High Reliability for Always-On Services
Hot-swappable PSUs/fans, BFD/NSF, and enterprise-level link protection ensure stable daily operation.
