DSS Model 8261

Introduction

DSS Network's Metro-Switch Model 8261 is an advanced high-performance, full-featured multilayer 6U Gigabit Ethernet switch fabric board. It features 12 ports of 10/100/1000 Base T Gigabit Ethernet over Copper with two 1000 Base SX/LX fiber uplinks. It is PICMG 2.16 fabric card compliant and compatible with both standard Compact PCI and PICMG 2.16 backplanes. All 12-ports may be routed to slots on the Compact PCI backplane or externally via rear I/O. A system management interface is also supported via the PICMG 2.9 IPMI interface. It optionally supports two 1000 base SX/LX gigabit fiber ports with standard 850nm or 1310nm SFF LC connectors via the front panel. It has an onboard RISC/DSP processor for local management and can be operated as a standalone or fully managed switch. LEDS are provided for each port showing link status, transmit and receive and link quality. All LEDS are multifunction and can be used for additional functions including cable testing and energy detection. It is also PICMG 2.1 R2.0 hot-swap compliant providing support for the hardware connection layer.

The model 8261 uses the latest advanced high-performance, full-featured and highly integrated 12-port Broadcom BCM5690 multilayer switch and BCM5464SR quad-port transceivers and is fully 802.3 compliant. It provides a fully non-blocking 24Gb/32 million frames per second aggregate switching fabric. The switching function supports an extended list of features including layer 3 switching, link aggregation, 802.1Q VLANs, 802.1D spanning tree and priority-based 802.1D/802.1p CoS/traffic class expediting and dynamic multicast filtering.

The Metro-Switch model 8261 12-port switch is targeted for OEMs and Systems Integrators for use in Data and Telecommunications products including switches, multiplexers, edge routers, media gateways and video broadcasting equipment. It is well suited for support of embedded broadband applications including Internet voice, digital video, IP security, network monitoring, military applications and test equipment. Ruggedized models including extended temperature and conformal coating are available.
