Connecting The HA100 with 2 UCM6510

This is the connection between HA100 and the 2 UCM6510s, one acting as primary server (providing online
service) and the other as backup server (it doesn't provide service until the primary server is down).

Environment

For the internal connection, we will assume that users have already the following environment items ready:
4 Ethernet cables and 2 T1/E1/J1 cables.
-
8 PSTN cables.
-
2 USB-to-RS485 serial cables.
-
2 UCM6510 (UCM A and UCM B).
-

Connection Steps

Please refer to followings steps for the basic internal connections between HA100, UCM A and UCM B:
1. Connect respectively the FXO port, FXS port, E1/T1/J1 port, WAN port and LAN port on UCM A to
the FXO-A port, FXS-A port, E1/T1/J1-A port, WAN-A port and LAN-A port on HA100.
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 the FXO port, FXS port, E1/T1/J1 port, WAN port and LAN port on UCM B to
the FXO-B port, FXS-B port, E1/T1/J1-B port, WAN-B port and LAN-B port on HA100.
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.
The following diagram illustrate the connection between the HA100 and 2 UCM6510 PBXs.
In this scenario, the HA100 separates the external port into the corresponding internal ports (A and B), by
default, the port A is always connected and port B is always disconnected, so only one UCM device is
successfully connected at one time. If the primary UCM (UCM6510 A) detects problem on itself, it will send
signaling to HA100 via USB-to-RS485 cable to switch the connection towards the backup server, or in case
the primary server is down by any reasons, for instance power outage, the HA100 will then switch the
connection from port A to port B, making port B successfully connected and having backup UCM (UCM6510
B) to provide service.
