Chapter 3. Installing optional devices This chapter provides instructions for installing optional hardware devices in the blade workstation. Instructions for removing some optional devices are provided in case you have to remove one device to install another. Installation guidelines Before you install optional devices in the blade workstation, read the following information: v Read the safety information that begins on page v and the guidelines in "Handling static-sensitive devices." This information will help you work safely. v Back up all important data before you make changes to disk drives. v Before you remove a hot-swap blade workstation from the BladeCenter unit, you must shut down the operating system and turn off the blade workstation. 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 workstation, or open or close a latch. v Orange on a component or an orange label on or near a component indicates that the component can be hot-swapped, which means that you can remove or install the component while the BladeCenter unit is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component. v For a list of supported optional devices for the blade workstation, go to http://www.ibm.com/servers/eserver/serverproven/compat/us/. System reliability guidelines To help ensure proper cooling and system reliability, do not operate the BladeCenter unit without a blade device or filler blade installed in each blade bay. See the documentation for your BladeCenter unit for additional information. Handling static-sensitive devices Attention: Static electricity can damage the blade workstation and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them. To reduce the possibility of damage from electrostatic discharge, observe the following precautions: v When you work on the BladeCenter T unit, use an electrostatic discharge (ESD) wrist strap, especially when you will be handling modules, optional devices, or blade workstations. To work correctly, the wrist strap must have a good contact at both ends (touching your skin at one end and firmly connected to the ESD connector on the front or back of the BladeCenter T unit). v Limit your movement. Movement can cause static electricity to build up around you. v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed circuitry. v Do not leave the device where others can handle and damage it. © Copyright IBM Corp. 2007 15
