HA100 Deployment Methods

There are two deployment methods for adding an HA100 and a secondary UCM6510 to an existing UCM6510 setup:

Method 1: Backup and Restore Configuration

• Step 1: Upgrade UCM A to firmware version 1.0.15.13 or higher, and create a full backup (backup_A).
• Step 2: Upgrade UCM B to the same firmware as UCM A, and “backup_A” to UCM B. UCM A and UCM B should now have same configuration and data.
• Step 3: Connect all the cables as described in [UCM6510 and HA100 Connection] section “HA100 Connection”. Make sure all ports A in HA100 are connected to UCM A, and all ports B are connected to UCM B.
• Step 4: Make sure UCM A, UCM B and HA100 are up and running. Access UCM_A’s web UI, enable HA under System Settings🡪HA.
• Step5: Save and apply changes before rebooting.

Method 2: Sync Configuration

• Step 1: Upgrade UCM A to firmware version 1.0.15.13 or higher, then make a full backup (backup_A).
• Step 2: Upgrade UCM B to same firmware as UCM A.
• Step 3: Setup the connections as described in the [UCM6510 and HA100 Connection], EXCEPT heartbeat connection between UCM A and UCM B.
• Step 4: Access UCM_A’s web UI, enable HA under System Settings🡪HA and reboot UCM A.
• Step 5: Establish the heartbeat connection between UCM A and UCM B. UCM A should now sync its configuration to UCM B.

HA100 Configuration Settings on the UCM6510

Usage restriction：

• Both primary UCM6510 and secondary UCM6510 should be using the exact same firmware version.
• The connection between primary UCM6510 to HA100 and the connection between secondary UCM to HA100 must be correct. The heartbeat port must be connected correctly.
• It is recommended to use high performance switch or router to connect HA to.
• When powering up the HA100, the UCM6510 must be using static IP.
• When users need replace device, please reset the new devices before connecting to HA.

This section provides the configuration steps for the HA functionality on the UCM6510.

1. Power up UCM6510(A), UCM6510(B) and HA100, after they boot up only the primary server UCM6510(A) can show the IP address.
2. Log in UCM6510(A) web UI and navigate to System Settings 🡪 HA 🡪 HA Settings
3. Enable heartbeat, configure heart beat port and heart beat timeout. Users can also configure hardware scan and failure switchover.

Note :

• Hardware Scan (optional): select the hardware ports that to be detected for failure. Only the configured ports can be allowed to select here.
• Failure Switchover (optional): select the hardware ports to switch after failure is detected. Only the selected ports in “Hardware Scan” are available here.

4. After the configuration, save and apply the change. The configuration will be sent to UCM6510(B) via heartbeat port and the two UCMs will reboot together.

The HA function has now started, if users need replace devices, it is recommended to reset the new devices first then connect into the setup.

HA100 Functionality

HA100 separates the external ports into the corresponding internal ports (A and B). Only one UCM6510 device is connected at any given time.

When the 2 UCM6510s connect to HA100 via port A and port B, the primary UCM6510 will use the external ports on HA100 for data transmission. The HA100’s RS485 port receives signaling from the UCM6510s to switch between Port A and Port B.

If the internal port A on HA100 is connected successfully to the corresponding port on primary UCM6510, the LED indicator for port A on HA100 will be solid green. The primary UCM6510 relies on HA100’s external ports for connections. In this case, the LED indicator for Port B on HA100 will not light up, and the backup UCM will not provide service.

For more details about UCM6510, please refer to online User Manual:

https://documentation.grandstream.com/knowledge-base/ucm6510-user-manual/

UCM6510 Failure Management

If the primary server (UCM6510 A) detects issues within itself, it will signal the HA100 via USB-to-RS485 cable to switch connection from Port A to Port B. The backup server (UCM6510 B) will then be successfully connected and resume service. If the primary server is suddenly down for any reason, the HA100 will automatically switch the connection from Port A to Port B, allowing the backup server (UCM6510) to resume services and minimizing the impact of the interruption.

HA100 Failure Management

The failure of HA100 will not cause the whole system to go down automatically.

The system will only go down if UCM master and UCM slave fail or UCM master and HA100 fail. For example, in a typical installation, UCM A is the master and UCM B is the slave. When HA100 goes down, it will not impact UCM A’s operation. And UCM A will detect that the HA100 is down and will send out alarm notifications via email. In this scenario, the whole network environment will be down if UCM A’s connections are lost. The HA100 setup should be reestablished before this happens.

Important Notes：

• When primary-secondary switchover happens, active calls will be cut off and cannot be recovered.
• Switchover will occur when both WAN or LAN connections are lost.
• When hardware scan and failure switchover are selected, the UCM will scan the selected interfaces. If failures are detected, the HA100 will perform primary-secondary switchover. For example, when hardware scan and failure switchover are selected for FXO, and the FXO cable is disconnected, it will trigger a switchover.
• For FXS port failure scan, the UCM will perform switchover only when there is an FXS chip hardware error and not when an FXS cable is disconnected.
• In a scenario where there is a persisting issue that triggers constant switchover, no switchovers will occur beyond the second one.
• Failure detection will detect only hardware failures.
• Data in external storage devices will not sync.
• If a switchover occurs, and UCM B assumes the Master role, UCM B will remain as Master until another switchover occurs.
• When upgrading UCM firmware, both UCM A and UCM B will be upgraded in the process. Both devices will reboot upon successful upgrade.
