PCI Backplane Removal PCI Backplane Removal The PCI backplane is located on the back of the I/O Card cage. I/O slot 1 is located on the outside of the PCI I/O card cage and slots 2, 3, and 4 are attached to the PCI backplane inside the I/O card cage. CAUTION Ensure that the system is shut down and power removed from the server before attempting removal or replacement of a component. To remove the PCI backplane from the server, perform the following steps: Step 1. Remove the I/O cables from the back of the server. Step 2. Remove the I/O card from slot 1. Step 3. Remove the I/O card cage from the server. CAUTION Do not scrape the I/O Backplane against the CPU heat sink when removing or replacing the card cage. Failure to heed this precaution could cause serious damage to the backplane and require replacement. Step 4. Remove all PCI cards. NOTE Note the order of PCI card installation prior to removal. Cards must be re-installed in the same slots, or I/O reconfiguration may be required. Step 5. Lay the I/O card cage, open side down, on a clean, dry surface. The PCI backplane is facing up. Step 6. Remove the T-10 retainer screw from the PCI backplane. Step 7. Slide the PCI backplane to one side, so that the retainer posts will clear the keyhole slots. Step 8. Grasp the PCI backplane by the edges and carefully remove it from the card cage. The following photograph shows the PCI Backplane. Chapter 255
