Installation guidelinesBefore you install optional devices, read the following information:v Read the safety information that begins on page v, the guidelines in “Workinginside the server with the power on” on page 27, and “Handling static-sensitivedevices” on page 28. This information will help you work safely.v When you install your new server, take the opportunity to download and applythe most recent firmware updates. This step will help to ensure that any knownissues are addressed and that your server is ready to function at maximum levelsof performance. To download firmware updates for your server, complete thefollowing steps.Note: Changes are made periodically to the IBM Web site. The actual proceduremight vary slightly from what is described in this document.1. Go to http://www.ibm.com/systems/support/.2. Under Product support, click System x.3. Under Popular links, click Software and device drivers.4. Click IBM System x3850 M2 or IBM System x3950 M2 to display the matrixof downloadable files for the server.For additional information about tools for updating, managing, and deployingfirmware, see the System x and xSeries Tools Center at http://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.v Before you install optional hardware devices, make sure that the server isworking correctly. Start the server, and make sure that the operating systemstarts, if an operating system is installed, or that a 19990305 error code isdisplayed, indicating that an operating system was not found but the server isotherwise working correctly. If the server is not working correctly, see “SolvingProblems” in the Installation Guide for diagnostic information.v Observe good housekeeping in the area where you are working. Place removedcovers and other parts in a safe place.v If you must start the server while the cover is removed, make sure that no one isnear the server and that no tools or other objects have been left inside theserver.v Do not attempt to lift an object that you think is too heavy for you. If you have tolift a heavy object, observe the following precautions:– Make sure that you can stand safely without slipping.– Distribute the weight of the object equally between your feet.– Use a slow lifting force. Never move suddenly or twist when you lift a heavyobject.– To avoid straining the muscles in your back, lift by standing or by pushing upwith your leg muscles.v Make sure that you have an adequate number of properly grounded electricaloutlets for the server, monitor, and other devices.v Back up all important data before you make changes to disk drives.v Have a small flat-blade screwdriver available.v You do not have to turn off the server to install or replace hot-swap powersupplies, hot-swap fans, hot-plug adapters, or hot-plug Universal Serial Bus(USB) devices. However, you must turn off the server before you perform anysteps that involve removing or installing adapter cables.v Blue on a component indicates touch points, where you can grip the componentto remove it from or install it in the server, open or close a latch, and so on.26 IBM System x3850 M2 and System x3950 M2 Type 7141: User’s Guide
