that is installed. See "Blade server Ethernet controller enumeration" for information
about how to determine the routing from Ethernet controller to I/O-module bay for
your blade server.
Note: Other types of blade servers, such as the BladeCenter HS20 Type 8678
You do not need to set any jumpers or configure the controllers for the blade server
operating system. However, you must install a device driver to enable the blade
server operating system to address the Ethernet controllers. For device drivers and
information about configuring your Ethernet controllers, see the Intel Ethernet
Software CD that comes with your blade server. For updated information about
configuring the controllers, go to the IBM Support Web site at
http://www.ibm.com/pc/support/.
Your Ethernet controllers support failover, which provides automatic redundancy for
your Ethernet controllers. Without failover, you can have one Ethernet controller
from each server attached to each virtual LAN or subnet. With failover, you can
configure more than one Ethernet controller from each server to attach to the same
virtual LAN or subnet. Any one of the integrated Ethernet controllers can be
configured as the primary Ethernet controller. If you have configured the controllers
for failover and the primary link fails, a secondary controller takes over. When the
primary link is restored, the Ethernet traffic switches back to the primary Ethernet
controller. (See your operating system device driver documentation for information
about configuring for failover.)
Important: To support failover on the blade server Ethernet controllers, the Ethernet
switch modules in the BladeCenter unit must have identical configurations.

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 or pass-thru module in I/O-module bay
2. Make sure that the ports on the switch module or pass-thru module are enabled
3. Enable only one of the Ethernet controllers on the blade server. Note the
4. Ping an external computer on the network connected to the switch module. If
