Intel® Server Compute Blade SBXD62 Installation and User’s Guide 41
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 I/O-module bay will vary based
on blade server type and the operating system that is installed. See
“Blade Server Ethernet
Controller Enumeration” on page 41 for information about how to determine the routing
from an Ethernet controller to an I/O-module bay for the blade server.
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
Broadcom NetXtreme Gigabit Ethernet
Software CD 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 Intel® Blade Server Chassis SBCE 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 that a blade server uses
through the 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 1.
2. Make sure that the ports on the switch module or pass-thru module are enabled (click
I/O-module Tasks
→
Management
→
Advanced Management in the management
module Web-based user interface).
3. Enable only one of the Ethernet controllers on the blade server. Note the designation
that the blade server operating system has for the controller.
