1Gbit/s Ethernet I/O ModuleThis chapter explains the features and specifications of this product.
1.1 Overview
This product is an expansion LAN card exclusive to BX620 S2 Server Blade. This product has a
dual-port (2 ports) LAN controller, and provides LAN connection completely separate/ independent
of the onboard LAN. The external access is performed via the Switch Blade installed to the network
blade slot 3 or 4 (NET3 or NET4) on the chassis.
One product can be added to one BX620 S2 Server Blade. The following figure shows a
configuration example when ten BX620 S2 Server Blades (slot 1 to 10) are installed in the chassis. In
this example, 1Gbit/s Ethernet I/O Modules are installed in all server blades for convenience of
explaining LAN connection between each 1Gbit/s Ethernet I/O Module and network blade, however,
1Gbit/s Ethernet I/O Modules do not necessarily need to be installed on all server blades.
