Switch 8800 720 Gbps Fabric Module – 1 x 10/100Base-TX – 1 x CompactFlash Card Slot
Product name: HP 720Gbps Fabric 8800 Module
Product number: JE196A
Product type: Connectivity Modules
Product series: HP Switch Fabric Modules
This Switch Fabric Module is the core of the 3Com Switch 8800 system.
This Switch Fabric performs route calculation and provides all Layer 3 switching functionality.
It also performs Layer 2 switching between interface modules and where on-board Layer 2 switching is not possible.
Based on the address-forwarding table, the hardware performs line-speed switching of Layer 2 / Layer 3 data packets.
In addition to switching functions, this Switch Fabric Module performs control and management functions for the system.
The management channel performs such functions as initialization and configuration of the system, data packet learning, protocol processing, and network management.
When a second fabric is installed in a Switch 8800, both switch fabrics are active, in essence doubling the performance of a switch compared to having just a single switch fabric; in addition, fabric resiliency is provided.
