VPX Chassis — Hybrid Switch
HybrId Switch Board
Hybrid Switch is a module that centrally switches both the PCIe-based high-speed data plane and the 10 Gigabit Ethernet control plane within a VPX chassis. The architecture combining two different communication types on a single card reduces system complexity while providing bandwidth flexibility.
- Fabric:PCIe Gen3
- Ethernet:10GbE L2/L3
- Feature:Dual-Plane Switching
Technical Specifications
| Feature | Value / Description |
|---|---|
| PCIe Fabric | PCIe Gen3 switch — x4 lanes to each payload slot |
| Ethernet Switch | 10GbE L2/L3 (1G / 10G / 40G support) |
| Front Panel Output | QSFP+ |
| Management Port | RJ45 or alternative connector |
| Control Unit | SOC / FPGA (for port management and monitoring) |
| Backplane Interfaces | PCIe Gen3 x4 payload links, IPMB, REF_CLK |
| Management | IPMC (VITA 46.11), I2C, IPMB, EEPROM |
