I/O module interface requirements
Your BladeCenter unit has two or four I/O-module bays and supports a
minimum of one hot-swap I/O module in I/O-module bay 1 or bay 2. Several
types of I/O modules are available to meet specific network requirements.
Each of the I/O modules must support the blade server interface to which it
connects. See http://www-947.ibm.com/support/ entry/portal/
documentation/ for a list of options available for your BladeCenter unit.
The blade server integrated Ethernet controllers support connection with the
Ethernet switch modules and pass-thru modules. The I/O module in
I/O-module bay 1 provides a network connection to one of the Ethernet
controllers in all the blade servers in the BladeCenter unit. To provide a
network connection for the second Ethernet controller in each blade server,
install an I/O module in I/O-module bay 2.
In BladeCenter units that support four I/O modules, if you install an I/O
expansion card on any blade server, you must install a hot-swap I/O module
that supports the interface type used in I/O-module bay 3 to obtain connection
1 for the I/O expansion card. To provide connection 2 for the I/O expansion
card, install an I/O module that supports the interface type used in
I/O-module bay 4. The I/O modules in I/O-module bay 3 and bay 4 provide
connections to all the I/O expansion cards in the BladeCenter unit.
