Synchronizing Firmware

Synchronize Firmware button.
This allows you to synchronize firmware between the units after upgrading the active unit to a
different version.
Clicking the Accept button does not synchronize firmware, but synchronizes settings from the
active to the idle unit.

Once HA is enabled, can the idle device be used separately?
No. Once HA is configured, only one device can be in use at any one time. During failover
the Idle device will become Active. Two devices in HA mode cannot be used as separate
SRA appliances.
What will happen if we remove the X3 interface cable from the devices?
If you remove the X3 (HA) cable then the IDLE device can be re-configured to work as a
standalone. However, this will cause an IP conflict, as both the primary and backup devices
have the same IP configuration.
Can the X3 interface settings be amended, once HA is enabled?
When HA is configured, the 'Edit' button for the X3 interface is grayed out and disabled. So
the interface setting for X3 cannot be changed once the devices are in HA mode.
Can the X0, X1 and X2 interface settings be amended once HA mode is set up?
