Clicking the [Execute] button starts transfer of the update data file between EM cards. Upon
completion of transfer, the firmware of the target EM card is updated.

After updating, the target EM card is rebooted
automatically. If the updating is executed on the active EM card, the
active EM card is switched to another EM card by switchover feature.
NOTES:

The combination of firmware revision available for synchronization
is as follows:
EM card that performs synchronization: Rev 06.00 or later
Another EM card: Rev 02.00 or later

To use this feature, you must be able to connect with both of Web
consoles of Active EM card and Standby EM card.
 If you are going to perform revision synchronization on EM card of
which revision is Rev 10.08 or earlier while the other EM card of
which revision is Rev 11.xx or later, the EM cards are not
synchronized to Rev 11.xx or later. In this case, perform
synchronization on Web console of Rev11.xx side.

You cannot undo this operation, therefore, take extreme care to
execute it.

When update process is completed and the EM card is rebooted, this
