v Around-the-clock access to the blade server, even if the server is turned off
At some time, you might need to flash the service processor to apply the latest
firmware. Download the latest firmware for your blade server service processor from
the IBM Support Web site at http://www.ibm.com/pc/support/. Use the BladeCenter
management module Web interface to flash the service processor. The Web
interface is described in the IBM
Eserver
BladeCenter Installation and User’s
Guide on the IBM BladeCenter Documentation CD.
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 the Ethernet
switch modules, which enables simultaneous transmission and reception of data on
the Ethernet local area network (LAN).
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
Broadcom
NetXtreme Gigabit 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/.
Note: Enumeration of the Ethernet controllers is operating-system dependent. For
example, the Ethernet controller located nearer the top of the blade server,
whose communications are routed through Ethernet switch module 1, is
designated as the first connection (or Local Area Connection) by Microsoft
Windows 2000, but is designated as the second connection (or eth1) by Red
Hat Linux Version 7.3. The Ethernet controller located nearer the bottom of
the blade server, whose communications are routed through Ethernet switch
module 2, is designated as the second connection (or Local Area Connection
2) by Microsoft Windows 2000 but is designated as the first connection (or
eth0) by Red Hat Linux Version 7.3. You can verify the designations through
your operating system settings or by testing:
1. Install only one Ethernet switch module, in switch bay 1.
2. Enable only one of the Ethernet controllers on the blade server. Make
note of the designation the blade server operating system has for the
controller.
3. Ping an external computer on the network connected to the switch
module.
If you can ping the external computer, the Ethernet controller you enabled is
the upper controller in the blade server and is associated with Ethernet
switch 1.
Your Ethernet controllers support failover, which provides automatic redundancy for
your Ethernet controllers. You can configure either one of the integrated Ethernet
controllers 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.)
