一、板卡概述
The VPX6-6902 is available in a variety of system configurations, and supports a number of standard OpenVPX profiles. Popular configurations include:
1. 24 x SRIO (x4) ports to the VPX backplane and 4x SRIO (x4) ports to the front, with no Ethernet switching.
2. 20 x SRIO (x4) ports to the VPX backplane and 4x SRIO (x4) ports to the front,along with 16x SerDes GbE ports and 2x 1000Base-T ports to the rear with an additional 2x 10GbE and one (1) 1000Base-T port to the front.
The VPX6-6902’s on-board management processor can be used to manage and configure the Ethernet switch, and also performs SRIO management and configuration. IPMI is also supported for system level management.

二、功能和技术指标：
- 6U VPX Form Factor, complies with OpenVPX / VITA-65 standards
- Combined SRIO Data plane and Ethernet Management and Control plane switch fabrics
- Enables easy implementation of scalable high performance centralized DSP clusters for small, medium and large systems
- Available with SRIO only, or SRIO + Ethernet switch fabricso SRIO switch offers up to 24x 4-lane ports to the backplane, and 4x 4-lane ports to the front. Second generation SRIO switching technology support both Gen-1 (1.25, 2.5 and 3.125 Gbaud) or Gen-2 (5.0 and 6.25 Gbaud) speeds Integrated Ethernet switch offers up to 16x SerDes GbE and 2x 1000Base-T ports to the VPX backplane, along with + 2x 10GbE and 1x 1000Base-T ports to the front.
- On-board management processor for both SRIO and GbE fabrics
- Supports star and dual-star topologies for redundant and fail-safe architectures
- Pre-configured for 3rd party SRIO diagnostic Probe to provide system monitoring, analysis and diagnostics
- Air-cooled and Conduction-cooled models available in all ruggedization levels (L0, L100,L200)
The VPX6-6902 is a combined management, control and data plane switch for small, mid-size and large 6U VPX systems. Supporting a centralized switch architecture in both star and dual-star topologies, the VPX6-6902 is available with Serial RapidIO (sRIO) switching alone, or with both sRIO dataplane and Ethernet management/control plane switching all in a single VPX slot.
The VPX6-6902 sRIO switch fabric supports both Gen-1 (1.25, 2.5, 3.125 GBaud) and Gen-2 sRIO (5.0 GBaud) data rates. Each of its 28 sRIO ports operates in x4 lane mode, offering up to 16 Gbps throughput per port.
The VPX6-6902 Ethernet switch supports Gigabit Ethernet links, with up to 22 ports to the backplane, and an additional port to the front panel. Two 10 GbE (XAUI) ports are also provide on the front panel for switch expansion or backbone connections. A full line-rate non-blocking architecture, combined with a managed Layer 2 feature set, ensures maximum performance and flexibility.
The VPX6-6902 is available in a number of port configurations. For applications requiring only sRIO switching, the VPX6-6902 provides a total of 24 ports to the backplane and 4 ports to the front panel (AC only). Each sRIO port supports 1 and 4-port widths.
This conforms to OpenVPX profile MOD6-SWH-24F.For applications requiring both sRIO and Ethernet switching, the VPX6-6902 provides 19 or 20 sRIO ports to the backplane, and adds 16 or 20 GbE SerDes + 2x 1000Base-T interfaces to the backplane, along with 2x 10 GbE XAUI and an additional 1000Base-T port to the front panel (AC only).
These configurations comply with OpenVPX profiles MOD6-SWH-16U20F and MOD6-SWH-20U19F.
