This concludes the hardware portion of the clock board upgrade. Continue with the next section, “Updating the System Flash PROM” to complete the procedure.
Updating the System Flash PROM
After replacing the clock board, update the system flash PROM. If you have internet access, the patch can be downloaded using the following procedure. If you do not have internet access, obtain the PROM patch software from your local Sun service provider.
After the system flash PROM is reprogrammed, the flash utility attempts to reboot the system. If the system fails to auto reboot, power cycle or reset the system by pressing the reset button.
