One day ,we want to upgrade an OSN6800 equipment from V100R003C02B01e to V100R004C04SPC800 ,the SCC type is TN11SCC .we check the original host software information and find the basic BIOS is 8.21.03,but in the version matching table of V100R004C04SPC800 it shows 8.20.36/8.20.35. As we all know , we can’t upgrade the basic BIOS in NG-WDM equipment . It means after we upgrade the OSN6800 to V100R004C04SPC800, the BIOS won’t match with the version matching table ,is it normal?
No problem . Because basic BIOS is used to lead the EXT-BIOS , and EXT-BIOS is used to lead host program . if the EXT-BIOS can start normally ,it means the BIOS works normally . It is not necessary that BIOS version strictly match with the version matching table .In the version matching table , the BIOS version is a recommendatory value . However, EXT-BIOS and host software must match exactly.
