Active PCI assembly The Active PCI assembly, mounted on the top rear of the server frame adjacent to the PCI and PCI-X adapters, contains one switch for each of the six adapters. This ensures that power is disconnected from the associated adapter if you attempt to open the adapter latch and remove an adapter. Note: v Read "Installation guidelines" on page 79. v Read the safety notices at "Safety notices (multilingual translations)" on page 260. v Read "Handling static-sensitive devices" on page 80. Complete the following steps to replace the Active PCI assembly: 1. Turn off the server (see "Turning off the server" on page 10) and disconnect all power cords and external cables; then, remove the top cover (see "Opening the cover" on page 82). 2. Disconnect the Active PCI assembly cable from the server. 3. Grasp the two adapter switch card release latches and slide the assembly away from the server chassis; then, lift it out of the server. Note: The illustrations in this document might differ slightly from the hardware being serviced. Release latches 4. To replace the Active PCI assembly, lower the assembly into place so that the lips on the bottom of the EMI shielding material fit into the chassis at the rear of the server, and slide the card into place until the two release latches snap securely. Then, connect the cable from the Active PCI assembly to the board. 5. Replace the top cover (see "Closing the cover" on page 125). 184 xSeries 445 Type 8870: Hardware Maintenance Manual and Troubleshooting Guide
