d. Press firmly on the captive screws and tighten them, alternating between screws until they are tight. Do not overtighten the screws by using excessive force. Attention: If you need to remove the heat sink after installing it, note that the thermal material may have formed a strong bond between the heat sink and the microprocessor. Do not force the heat sink and microprocessor apart; doing so can damage the microprocessor pins. Loosening one captive screw fully before loosening the other captive screw helps break the bond between the components without damaging them. 8. If you have other options to install, install them now. Otherwise, continue with "Completing the installation" on page 47. Replacing the battery When replacing the battery you must replace it with a lithium battery of the same type, from the same manufacturer. To avoid possible danger read and follow the safety statement below. To order replacement batteries, call 1-800-772-2227 within the United States, and 1-800-465-7999 or 1-800-465-6666 within Canada. Outside the U.S. and Canada, call your IBM reseller or IBM marketing representative. Note: After you replace the battery, you must reconfigure your server and reset the system date and time. Statement 2 CAUTION: When replacing the lithium battery, use only IBM Part Number 33F8354 or an equivalent type battery recommended by the manufacturer. If your system has a module containing a lithium battery, replace it only with the same module type made by the same manufacturer. The battery contains lithium and can explode if not properly used, handled, or disposed of. Do not: v Throw or immerse into water v Heat to more than 100°C (212°F) v Repair or disassemble Dispose of the battery as required by local ordinances or regulations. Complete the following steps to replace the battery: 1. Read "Safety information" on page 101 and "Installation guidelines" on page 25., and follow any special handling and installation instructions that come with the replacement battery. 2. Turn off the server and all attached peripheral devices. Disconnect all power cords; then, disconnect all external signal cables from the server. 3. Remove the server from the rack; then, remove the server cover (see "Removing the cover and bezel" on page 27). 4. Uncover the system board by pulling the PCI adapter shield to one side. Attention: Do not remove the PCI adapter shield from the server. 42 325 Type 8835: Hardware Maintenance Manual and Troubleshooting Guide Eserver
