NVRAM on the Controller Board
SC195 (Machine serial number error) will occur if the NVRAM is not attached.
Mounting the NVRAM in the wrong direction will cause a short circuit between the controller board and the
NVRAM, and.all components will have to be replaced.
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 data (“ALL”) using SP5-990-001. (SP5-990-001)
3.
Turn OFF the main power.
4.
Insert a blank SD card into Slot 2.
5.
Turn ON the main power.
6.
Upload the NVRAM data to the blank SD card using SP5-824-001 (NVRAM Data Upload).
7.
Turn OFF the main power, and then disconnect the AC power cord.
8.
Remove the SD card containing the NVRAM data from Slot 2.
9.
Replace the NVRAM on the controller board with a new one.
10.
Connect the AC power cord, and then turn ON the main power.
When you do this, SC995-02 (Defective NVRAM) will be displayed. However, DO NOT turn off the
main power. Continue with this procedure.
11.
Re-insert the SD card that you removed in Step 5 back into Slot 2.
12.
Download the old NVRAM data from the SD card onto the new NVRAM using SP5-825-001 (NVRAM Data

Remove the SD card from Slot 2.
15.

step 2 above (except for the value of the total counter).
Do all of the following if SP5-824-001 (NVRAM Data Upload) and SP5-825-001 (NVRAM Data
