QuadroM32x/8L/26x/12Li/26xi; (SW Version 5.3.x)

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.

Fig. II-75: Redundancy Settings list

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

Virtual IP Address text fields require the virtual IP address of the device where the configuration is done. Virtual Subnet Mask text fields require

the virtual subnet mask of the device where the configuration is done. These two parameters identify an alternate IP network of the LAN interface

which stays unchanged when the device switches its mode (from master to backup or vice versa). The configuration and voice data synchronization

daemon uses this IP address to communicate with the second Quadro.

Redundant Device Virtual IP Address text fields require an alternate IP address of the LAN interface of the second Quadro.

Synchronization Interval text field requires the period of time (in seconds) between two consecutive configuration and voice data synchronizations

from master to backup device.

Backup Device GUI Access Port text field is present on the master device only and requires the port used for accessing the GUI of the backup

device through master.

Swap Master Device button is used for manual swapping of functionality of master and backup devices. This action will result in rebooting the

current master. After rebooting the current master device will start running in a backup mode. Switching the backup to master starts all applications

on Quadro and causes all IP phones to reboot. The swapping takes around 1 minute however another 1-3 minutes are required in order to reboot all

the IP phones connected to redundant system. If backup device before swapping was in passive mode then after swapping the master will start

running as backup in passive mode, otherwise if it was in active mode then master will start running as backup in active mode.

Download system logs link is only present on backup device and is used to download system logs to the local PC as a *.tar archive file. These logs

can then be used by the

Epygi Technical Support Office to determine the problem that has occurred on your Quadro.
