Important: To support failover on the blade server Ethernet controllers, the Ethernet switch
modules in the SBCE unit must have identical configurations to each other.
Blade server Ethernet controller enumeration
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.
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:
1.
Install only one Ethernet switch module in I/O module bay 1.
2.
Make sure the ports on the switch module are enabled (Switch Tasks > Management >
Advanced Switch Management in the management module Web-based user interface).
3.
Enable only one of the Ethernet controllers on the blade server. Note the designation the blade
server operating system has for the controller.
4.
Ping an external computer on the network connected to the switch module. If you can ping the
external computer, the Ethernet controller you enabled is associated with the switch module in
I/O module bay 1. The other Ethernet controller in the blade server is associated with the switch
module in I/O module bay 2.
Two Ethernet switch modules are required to use both dual Ethernet channels of the blade server.
One Ethernet switch module is installed in the SBCE unit and is fully functional with blade server
integrated Ethernet channel ETH0. If the second blade server integrated Ethernet channel ETH1 is
configured, it is unable to communicate with network resources.
Within the SBCE unit, Ethernet switch modules are physically wired independently to the integrated
Ethernet controller channels of each blade server: the ETH0 Ethernet controller channel on the blade
server is wired to the top Ethernet switch module and the ETH1 Ethernet controller channel on the
blade server is wired to the bottom Ethernet switch module. Two Ethernet switch modules are
required to use both blade server Ethernet channels.
See the SBCE Installation and User’s Guide for more information.
