If you are installing a new NVRAM/TOD module, the NVRAM/TOD must be programmed by a Sun authorized service representative before your system can resume normal operation. If you are installing a new main logic board, remember that you can migrate your former NVRAM/TOD module in order to preserve your system's host ID and Ethernet address.

For information about setting the flash PROM jumpers to enable you to program the NVRAM, see "3.16 How to Set the Flash PROM Jumpers".
