III-5.
Other notes
1)
Similar to the PCBs for regular service, the upgraded PCBs also have no serial number
information. Because of that, the upgraded PCBs are not supported by the serial number display
mode of the service mode.
2)
Because the network module that has the MAC address information is included in the upgrade
PCB, the MAC address is changed after the upgrade.
3)
After the upgrade is performed, the product cannot be returned to the state before the
upgrade.
