Important: To avoid problems and to maintain proper system performance, always make sure that the BIOS, service processor (BMC), and diagnostic firmware levels are consistent for all blade servers within the SBCE unit. 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 Ethernetcompatible 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 62 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 servers, such as the Intel® Server Compute Blade SBX82, that are installed in the same SBCE unit as the Intel® Server Compute Blade SBXD132 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 Broadcom NetXtreme Gigabit Ethernet Software CD that comes with the blade server. For updated information about configuring the controllers, see http://support.intel.com/support/. 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 operatingsystem 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 SBCE 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 that a blade server uses through the operating-system settings. 62 Intel® Server Compute Blade SBXD132 Installation and User's Guide
