Page 109: Installing A Microprocessor And Heat Sink
Installing a microprocessor and heat sink To install a microprocessor and heat sink, complete the following steps. Note: The following illustration shows how to install a microprocessor and heat sink in the blade server; installing a microprocessor and heat sink in the MPE unit is similar.
Page 110 Attention: v Do not press the microprocessor into the socket. v Make sure that the microprocessor is oriented and aligned correctly in the socket before you try to close the microprocessor retainer. 4. Center the microprocessor over the microprocessor socket. Align the notches on both sides of the microprocessor with the notches in the socket and carefully place the microprocessor into the socket.
Page 111: Removing The System Board Assembly
Removing the system board assembly Note: This section describes how to remove components from the blade server when the system board assembly is being replaced; removing components from the MPE unit when MPE board assembly is being replaced is similar. When replacing the system board, you will replace the system board and blade base as one assembly.

Page 113: Chapter 5. Configuration Information And Instructions
This chapter provides information about updating the firmware and using the configuration utilities. Firmware updates IBM periodically makes BIOS, service processor (BMC), and diagnostic firmware updates available for the blade server. Go tohttp://www.ibm.com/bladecenter/ to download the latest firmware for the blade server; then, install any updates using the instructions that are included with the downloaded file.
Page 114: Blade Server Ethernet Controller Enumeration
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://www.ibm.com/bladecenter/. The Ethernet controllers in your blade server support failover, which provides automatic redundancy for the Ethernet controllers.
Page 115: Configuring A Sas Raid Array
RAID level-0 (striping) or RAID level-1 (mirroring) array under an operating system that is listed at http://www.ibm.com/servers/eserver/serverproven/compat/us/. For more information, see the Installation and User’s Guide. If an optional BladeCenter Storage Expansion Unit 3 is installed, you can use it to control all of the SAS hard disk drives installed in the blade server.
