To install a replacement system board, install the guide bracket assembly for the SEC cartridge. The assembly is keyed for correct insertion (see Figure 4-25). Then install the SEC cartridge and heat sink assembly. Transfer the SIMMs to the new system board, and set the configuration jumpers to match the old sys- tem board.

When installing the new system board in the computer, push the system board against the back of the chassis so that the system board makes firm contact with the I/O gasket to prevent EMI leakage.

CAUTION: Failure to install the system board exactly as described may result in EMI leakage that could interfere with other electronic devices.
