Chapter 4. Installing and removing replaceable units This chapter provides instructions for replacing units on the blade server. Replaceable units are components, such as memory modules, and I/O expansion cards. Some removal instructions are provided in case you need to replace one replaceable with another. You can replace the following items: v Battery v Front bezel assembly (control panel) v Blade server cover v Impedance air baffles v DIMM fillers v System board You can add or remove the following optional items: v Cisco 4X Infiniband Expansion Card for IBM BladeCenter v InfiniBand 4X DDR Expansion Card (CFFh) v I/O buffer DDR2 memory modules v SAS expansion card v BladeCenter Expansion unit Note: If you wish to install the InfiniBand 4X DDR Expansion Card (CFFh) you must install Red Hat Enterprise Linux 5.2 or higher. Installation guidelines Before you begin, read the following: v Read the safety information beginning on page vii and the guidelines in "Handling static-sensitive devices" on page 30. This information will help you work safely with the blade server and components. v You do not have to turn off the blade server or disconnect the BladeCenter unit from power to install or replace any of the hot-swappable modules on the rear of the BladeCenter unit. v Before you remove a hot-swappable blade server from the BladeCenter unit, you must shut down the operating system on it by typing the shutdown -h now command or choosing the shut down option from your GUI. See "Turning off the blade server" on page 4 for details. You do not have to shut down the BladeCenter unit itself. v Blue on a component indicates touch points, where you can grip the component to remove it from or install it in the blade server or BladeCenter unit, open or close a latch, and so on. v Orange on a component or an orange label on or near a component indicates that the component can be hot-swapped. You can remove or install the component while the blade server or BladeCenter unit is running providing the blade server or BladeCenter unit and operating system support the hot-swappable capability. Orange can also indicate touch points on hot-swappable components. See the instructions for removing or installing a specific hot-swappable component for any additional procedures that you might have to perform before you remove or install the component. © Copyright IBM Corp. 2006, 2008 29
