Network topology

The typical network topology for an BladeCenter S system is a single chassis with one or more blade servers. These servers communicate with devices on the external network through an I/O module that is installed in the chassis. Management of the blade servers is performed remotely through the advanced management module.

An Ethernet switch module in I/O module bay 1 of the BladeCenter S chassis can connect all of the blade servers to the external network.
Note: There are normally multiple linkages from the I/O module to the external network.

If you install an Ethernet switch module in I/O module bay 2, remember that you will also need to install an Ethernet expansion card option on each of the blade servers that will access the Ethernet switch module.
