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.
Powered by an advanced hardware platform and revolutionary software functionalities, the connection
between the UCM6510 and HA100 offers a breakthrough turnkey solution for converged voice, video, data,
fax, security surveillance, and mobility applications out of the box without any extra license fees or recurring
costs.

Optional Connections
Please refer to the following steps for optional connections on the HA100:
1. For PSTN connection: Connect a PSTN cable to the FXO external port on HA100.
2. For Analog phone/Fax connection: Connect analog phone or FAX machine to the FXS external
port on HA100.
3. For T1/E1/J1 connection: Connect your digital connection cable from the service provider side to
the T1/E1/J1 external port on HA100.

HA100 User Manual
P a g e | 13
4. For LAN connection: Connect one end of the Ethernet cable to the LAN external port on HA100
and the other end to switch, hub or etc.
Connecting HA100 with 2x UCM6510s
In the 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.
Setup Requirements
The internal connection setup will require the following items:
•5x RJ45 cables (Ethernet).
•2x RJ48 cables (If using T1/E1/J1 trunk).
•8x RJ11 cables (If using PSTN trunks and/or analog devices).
•2x USB-to-RS485 serial cables.
•2x UCM6510 (UCM A and UCM B) using firmware 1.0.15.13 or higher.
UCM6510 and HA100 Connection
Please refer to followings steps for the basic internal connections between HA100, UCM A(Master) and
UCM B(Slave):
1. Connect respectively UCM A’s Line port (FXO), Phone port (FXS), E1/T1/J1 port, WAN port and
LAN port to HA100’s FXO-A port, FXS-A port, E1/T1/J1-A port, WAN-A port, and LAN-A port.
2. Use the USB-to-RS485 serial cable to connect UCM A’s USB port to the RS485-A port on HA100.
3. Connect respectively UCM B’s Line port (FXO), Phone port (FXS), E1/T1/J1 port, WAN port and
LAN port to HA100’s FXO-B port, FXS-B port, E1/T1/J1-B port, WAN-B port, and LAN-B port.
4. Use the USB-to-RS485 serial cable to connect UCM B’s USB port to the RS485-B port on HA100.
5. Use Ethernet cable to connect the Heartbeat ports on Primary UCM A and Backup UCM B.
Note: Since the UCM6510 has only one USB port, users are recommended to use a USB hub if they want
to use an external USB storage device along with the HA100 module.
The following diagram illustrates the connection between the HA100 and 2x UCM6510 PBXs.

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.
Figure 9: HA Settings on the UCM6510
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 User Manual

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.

HA100 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 and 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.
