NVRAM on the controller board
•
SC195 (Machine serial number error) will be displayed if you forget to attach the
NVRAM.
•
Passwords for the Supervisor and Administrator 1 will be discarded later in this
procedure.
•
If you mounted the NVRAM in the wrong direction, each component needs to be
replaced because a short circuit was caused in the controller board (PCB24) and the
NVRAM.
•
Installing a new NVRAM initializes SPs and issues an SC. Reset the SC with the
procedure below.
1.
Make sure that you have the SMC report (factory settings). This report comes with the
machine.
2.
Output the SMC log using one of the following methods:
To print SMC log data, execute SP5-990-001.
To save SMC log data to an SD card, execute SP5-992-001 (
SMC List Card Save
Function ).
3.
Turn OFF the main power switch (SW1).
4.
Insert a blank SD card in the SD slot 2, and then turn ON the main power switch (SW1).
5.
Use SP5-824-001 to upload the NVRAM data from the controller board (PCB24).
•
Make sure to note the following SP settings as they will not be automatically
uploaded to the SD card. These settings will be input manually in Step 24.

Make sure the customer has a backup of their address book data. If not, obtain the backup
by referring to SP5-846-051.
