Background Information
Risk of system crash!
If an upgrade is done while operating units with a HW or ESW that does not match the state or version given in this Application Note, the FOX61x may get into an operation state that doesn’t allow to provide services as expected.
Also in case of complying with the HW and the ESW versions given in this Application Note there is a small risk of getting the FOX61x into an operation state that doesn’t allow to provide services as expected after the upgrade.
→ In such a case you should restore the previous configuration and contact Hitachi Energy technical support (see section Technical Support).
→ Make sure that you save the NE configuration and create a backup file before proceeding to the upgrade procedure via the FOXCST menu function “File > Save Configuration to Disk …” or “File > Save Configuration to Disk As …”. Save the NE configuration as .tar file.
