INTRODUCTION Thank you for using Grandstream HA100. To meet the requirements of our customers, Grandstream has released the HA100, a module designed to implement the High Availability failover feature for our enterprise grade IP-PBX UCM6510. It contains a set of external ports and splits each of them into two internal ports: Port A and Port B. The ports on the UCM6510 A and UCM6510 B should be connected to each Port A and Port B respectively. The external ports on the HA100 provide PBX service.
HA100 DEPLOYMENT METHODS Before deploying and configuring the HA100, the unit needs to be properly powered up and connected. This section describes detailed information about the HA100 interfaces and the steps needed for installing and connecting the HA100. This section provides the connection types and steps needed for connecting the HA100 with 2 UCM6510s. Powering and Connecting the HA100 The external connections are used for the following purposes: Powering up the HA100. Network connection.
4. For LAN connection: Connect one end of the Ethernet cable to the LAN external port on HA100 and the other end to a switch, hub or etc. Connecting the HA100 with 2x UCM6510s In a connection between HA100 and 2x UCM6510s, one UCM6510 will function as the primary server and provide online services. The other UCM6510 will function as a backup server and will not provide services until the primary server is down.

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: Create a full backup for UCM A (backup_A_1). (This backup is created in case any configuration is lost during upgrading in step 2). Step 2: Upgrade UCM A to firmware version 1.0.15.16 or higher. Then create a full backup on UCM A (backup_A_2).
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 SettingsHA and reboot UCM A. Step 5: Establish the heartbeat connection between UCM A and UCM B.
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.
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.
SYSTEM UPGRADE Upgrading HA100 As we advise to always keep maintaining and upgrading the firmware on all your Grandstream devices, users could download the latest firmware version of HA100 module from the following link: http://www.grandstream.com/support/firmware/ After this, please follow below steps in order to upgrade the unit: 1. From the web GUI, navigate under the menu System SettingsHAHA Deconcentrator Firmware Upgrade. 2. Ensure that the active UCM’s RS485 cable is connected to the HA device.
