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, make sure that the server is workingcorrectly. Start the server, and make sure that the operating system starts, if anoperating system is installed, or that a 19990305 error code is displayed,indicating that an operating system was not found but the server is otherwiseworking correctly. If the server is not working correctly, see the ProblemDetermination and Service Guide on the IBM System x Documentation CD fordiagnostic 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 server cover is removed, make sure that noone is near 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, a small Phillips screwdriver, and a T8 torxscrewdriver available.v You do not have to turn off the server to install or replace hot-swap powersupplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.However, you must turn off the server before you perform any steps that involveremoving or installing adapter cables and you must disconnect the power sourcefrom the server before you perform any steps that involve removing or installing ariser card.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.v Orange on a component or an orange label on or near a component indicatesthat the component can be hot-swapped, which means that if the server andoperating system support hot-swap capability, you can remove or install thecomponent while the server is running. (Orange can also indicate touch points onhot-swap components.) See the instructions for removing or installing a specifichot-swap component for any additional procedures that you might have toperform before you remove or install the component.v When you are finished working on the server, reinstall all safety shields, guards,labels, and ground wires.v For a list of supported optional devices for the server, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.System reliability guidelinesTo help ensure proper system cooling and system reliability, make sure that thefollowing requirements are met:Chapter 2.
