The non-volatile random access memory/time of day (NVRAM/TOD) module contains the system host identification (ID) and Ethernet address. You may be migrating a functioning NVRAM/TOD module to a new main logic board in order to preserve host ID information. However, if you are replacing a defective NVRAM/TOD module and want to retain the same host ID, consult your authorized Sun sales representative or service provider.

3.7.2 What to Do

1. Locate the NVRAM/TOD module and its carrier on the main logic board.

2. Grasp the NVRAM/TOD carrier assembly at each end and pull straight up.

   If necessary, gently rock the NVRAM/TOD from side to side to facilitate removal.

   

3. Place the NVRAM/TOD module and carrier on an antistatic mat.
