Table 10 summarizes the types of modules that can be used in each I/O-module
bay.

Notes:
1. The enumeration of the Ethernet controllers in a blade server is
operating-system dependent. You can verify the Ethernet controller designations
a blade server uses through your operating system settings.
2. The routing of an Ethernet controller to a particular I/O-module bay depends on
the type of blade server. You can verify which Ethernet controller is routed to
which I/O-module bay by using the following test:
v Install only one Ethernet switch module or pass-through module, in
I/O-module bay 1.
v Make sure the ports on the switch module or pass-through module are
enabled (I/O Module Tasks
management module Web-based user interface).
v Enable only one of the Ethernet controllers on the blade server. Note the
designation the blade server operating system has for the controller.
v Ping an external computer on the network connected to the switch module or
pass-though module.
If you can ping the external computer, the Ethernet controller you enabled is
associated with the I/O module in I/O-module bay 1. The other Ethernet
controller in the blade server is associated with the I/O module in I/O-module
bay 2.

Permissible I/O module
One of the following
combinations:
v Two Ethernet switch
modules
v Two pass-through modules
v One Ethernet switch
module and one
pass-through module
One of the following
combinations:
v Two Ethernet switch
modules
v Two fibre-channel switch
modules
v Two pass-through modules
Important:
v The modules used must
support the network
interface used on the I/O
expansion options.
v The I/O modules in bays 3
and 4 must the same type.
