Redundancy Settings
Redundancy feature is used to increase Quadro device availability using second Quadro as a backup unit. This requires two units running the same
firmware version and connected to each other through Ethernet or LAN ports, depending on the device model.
Please Note:
The Redundancy feature is available only for QuadroM32x.
The idea of redundancy is to ensure uninterrupted functionality of the Quadro. The Redundancy Settings should be configured on both Quadros.
One of the Quadros is configured as a master, the second one as a backup unit.
Please Note:
To setup a redundant network, you should first startup the master device with all attached IP phones and other devices, make sure it
works normally and then startup the backup device.
If the master device becomes unavailable, which can be caused by power loss, reboot or network malconfiguration, the second Quadro becomes
automatically available and starts to run as a master device. Depending on the configuration, the second Quadro can remain master or go to the
backup mode once the first device becomes available again.
Attention:
During failover procedure all active calls will be disconnected and the system will be out of service during 2-5 minutes (depending on the
number of IP phones connected to the system), which is needed for running the applications and rebooting the phones. If there are IP phones in the
network that are not auto configured by Quadro (IP phones not supported by Epygi) or IP phones with the changed login name and password, you
will need to reboot them manually. After failover the license keys, firmware and language pack are not being transferred from the master to backup
Quadro therefore, so make sure both Quadros are configured identically in the redundant network before enabling redundancy mechanism.
When you login to the device which runs in a backup mode, only
Redundancy Settings
are available. All other GUI configuration settings are non
editable and automatically synchronized with the master device's configuration.
To ensure the interaction between the master and slave devices, corresponding configuration should be done in the Redundancy Settings on both
devices.
Enable Redundancy
checkbox is used to enable the
redundancy functionality on the Quadro.
Active Device Mode
drop down list is only present on backup
device and is used to adjust the behavior of the backup
device during unavailability of master device. When
Active
is
selected, backup device will become master once the original
master device became unavailable. When
Passive
is
selected, backup device stops its synchronization with the
master device and will not take over the control even when
the original master got failed unless
Swap Master Device
button is pressed on the master Quadro. The
Passive
mode
is used for firmware update or language pack updates on
master device when a reboot is required. After the reboot of
master device, the
Active Device Mode
on the backup
device should be changed back to
Active
to restore the
redundant network functionality.

Router ID
text field unique ID (values 1 and up) identifying master and backup devices. The same value must be set on both Quadros.
