4.5 Configuring the Gigabit Ethernet controllers
Two Ethernet controllers are integrated on the blade server system board. Each controller
provides a 1000 Mbps full-duplex interface for connecting to one of the Ethernet-
compatible I/O modules in I/O-module bays 1 and 2, which enables simultaneous
transmission and reception of data on the Ethernet local area network (LAN). Each Ethernet
controller on the system board is routed to a different I/O module in I/O-module bay 1 or
bay 2. The routing from an Ethernet controller to an I/O-module bay varies according to
the blade server type and the operating system that is installed. See
Blade server Ethernet
controller enumeration on page 45 for information about how to determine the routing from
an Ethernet controller to an I/O-module bay for the blade server.
Note:
Other types of blade server might have different Ethernet controller routing. See the
documentation that comes with the other blade servers for information.
You do not have 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 the Ethernet controllers, see the
Resource DVD that comes with the blade
server.
The Ethernet controllers in your blade server 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 the 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 Blade Chassis must have identical configurations.
