I/O module bay 2
supports an optional I/O module, such as an Ethernet switch or pass-thru module,
that connects to the Ethernet controllers on the Ethernet expansion
card option in each of the blade servers.
Note: If you install
an I/O module in I/O module bay 2, you will also need to install an expansion card option, such as the 2/4 Port Ethernet Expansion
Card, in each blade server that will access the external Ethernet
network through the switch module in I/O module bay 2.
You must use a filler in the bay if no I/O
module is installed.
