Blade server Ethernet controller numbering
The numbering of the Ethernet controllers in a blade server is operating-system
dependent. You can configure the blade server Ethernet-controller designations
by modifying your operating-system settings.
The routing of an Ethernet controller to a particular I/O-module bay depends
on the type of blade server. You can find out which Ethernet controller is
routed to which I/O module bay by completing the following steps:
1.
Install an Ethernet-switch module or pass-thru module in I/O-module bay
1.
2.
Make sure that the ports on the Ethernet-switch module or copper
pass-thru module are enabled (
I/O Module Tasks > Management >
Advanced Management
in the management module Web-based user
interface).
3.
Enable one of the Ethernet controllers on the blade server. Make a note of
the designation for the controller.
4.
Ping an external computer on the network connected to the I/O module. If
you can ping the external computer, the Ethernet controller that 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.
If the Ethernet controller that is associated with I/O-module bay 1 does not
have the designation that you want, modify the blade-server operating-system
settings to change the Ethernet-controller designations.
In a BladeCenter unit that supports four I/O modules, if you have installed an
I/O expansion card on a blade server, communications from the option are
routed to I/O-module bays 3 and 4. You can make sure which controller on the
card is routed to which I/O-module bay by performing the same steps, using a
controller on the I/O expansion card and a compatible Ethernet-switch module
or copper pass-thru module in I/O bay 3 or 4.
