CMOS jumper For normal operation of the system, a jumper is installed on pins 1 and 2 of the complimentary metal oxide semiconductor (CMOS) jumper. See "Clearing CMOS" on page 20 for information about the CMOS jumper. Before you begin Before you begin to install options in the server, read the following information: v Become familiar with the safety and handling guidelines provided in: - "Safety information" on page 125; - "Handling electrostatic discharge-sensitive devices" on page 129; and - "Safety notices (multi-lingual translations)" on page 130. These guidelines will help you work safely while working with the server or options. v When you need to access the inside of the server to install options, you might find it easier to lay the server on its side. If you do so, rotate the two front feet in towards the server, so they do not break off due to the weight of the server. v Before you place the server in an upright position, rotate the two front feet a quarter turn away from the server. For complete details, see "Moving the stabilizing feet" on page 46. v Make sure that you have an adequate number of properly grounded electrical outlets for the server, monitor, and any other options that you intend to install. v Back up all important data before you make changes to disk drives. v For a list of supported options for the 200, refer to http://www.ibm.com/pc/us/compat on the World Wide Web. Working inside the server with the power on The server is designed with safety in mind. Follow these guidelines when you work inside a server that is turned on: v Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before working inside the server; do not wear cuff links while you are working inside the server. v Do not allow your necktie to hang inside the server. 44 Hardware Maintenance Manual: xSeries 200
