NVRAM (EEPROM) on the BiCU
• Keep NVRAMs away from any objects that can cause static electricity. Static electricity can
damage data in the NVRAM.
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 ([SP Print Mode]-[All (Data List)]).
To save SMC log data to an SD card, execute SP5-992-001 ([SP Text Mode]-[All (Data List)]).
3.
Turn OFF the main power.
4.
Insert a blank SD card in SD slot #2, and then turn ON the main power.
5.
Upload the NVRAM data from the BiCU using SP5-824-001.
6.
Turn OFF the main power and disconnect the power plug.
7.
Replace the NVRAM on the BiCU with a new one.
• Make sure the NVRAM [A] is installed at the correct mounting location and orientation. Install
the NVRAM so that the indentation on the NVRAM corresponds with the mark [B] on the
BiCU.
• Incorrect installation of the NVRAM will damage both the BiCU and the NVRAM
8.
Connect the power plug and turn ON the main power.
9.
Select the destination setting (SP5-131-001 –NA: 1, EU/AA/TWN/CHN: 2).
• After changing the EEPROM, some SPs do not have the correct values.
• Because of this, steps 10 to 12 must be done.
