Central Electronics Complex (CEC) Backplane
Before performing the following procedure, read the “Safety Notices” on page xi.
To perform this procedure you will need to remove and install the PCI riser card. To
remove or install the PCI riser card from its docking connectors, requires a considerable
amount of force. If you are servicing a Model 6C4, it is strongly recommended that the
system drawer be removed from the rack. If you are servicing a Model 6E4, it is
strongly recommended that the system be placed on its side, on a flat and stable
surface. To avoid potential breakage, the system front foot must not be resting on the
surface.
CEC Backplane Removal
Attention: Before you remove or disconnect any components, record their location.
Before removing the CEC backplane from the system for servicing or replacement,
record the settings of any jumpers located on the CEC backplane.
To remove the CEC backplane (system board), do the following:
1. On a Model 6C4, open the front and rear rack doors and place the system into the
