IMPORTANT:
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 the Active EM card is earlier than Rev. 10.08 and the Standby EM
card is Rev. 11.xx or later, the EM cards are not synchronized to
Rev 11.xx or later. In this case, perform EM switchover to switch
between the Active EM and the Standby EM, then perform
synchronization.
 You cannot undo this operation, therefore, take extreme care to
execute it.
