You do not have to set any jumpers or configure the controllers for the blade
workstation operating system. However, you must install a device driver to enable
the blade workstation operating system to address the Ethernet controllers. For
device drivers and information about configuring the Ethernet controllers, see the
Broadcom NetXtreme Gigabit Ethernet Software CD that comes with the blade
workstation. To find updated information about configuring the controllers, see
http://www.ibm.com/bladecenter/.
The Ethernet controllers support failover, which provides automatic redundancy for
the Ethernet controllers. Without failover, you can have only 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. Either 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, the 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 workstation Ethernet controllers, the
Ethernet switch modules in the BladeCenter unit must have identical configurations.
Blade workstation Ethernet controller enumeration
The enumeration of the Ethernet controllers in a blade workstation is
operating-system dependent. Through the operating-system settings, you can verify
the Ethernet controller designations that a blade workstation uses.
The routing of an Ethernet controller to a particular I/O-module bay depends on the
type of blade workstation. 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 workstation. Note the
4. Ping an external computer on the network that the switch module is connected
If you have installed an expansion card in a blade workstation, communication from
the expansion card is routed to I/O-module bays 3 and 4, if these bays are
supported by your BladeCenter unit. You can verify which controller on the card is
routed to which I/O-module bay by performing the same test and using a controller
on the expansion card and a compatible switch module or pass-thru module in
I/O-module bay 3 or 4.

to. If you can ping the external computer, the Ethernet controller that you
enabled is associated with the switch module in I/O-module bay 1. The other
Ethernet controller in the blade workstation is associated with the switch module
in I/O-module bay 2.
