If two IAG devices are deployed in high availability mode (HA), wire the two devices to the external network and internal network, as shown in the following figure:

Follow the instructions below to wire the two devices:

• Use standard RJ-45 Ethernet cable to connect the WAN1 interfaces of the two IAG devices to the same switch (if the multi-line function is applied, the wiring method is the same: connect the WAN interfaces of the two devices to the same external line), and then connect the switch to other networking devices, such as a router, fiber optical transceiver, and ADSL Modem, etc.

• Use the Console cable (among the accessories) to connect the Console interfaces of the two IAG devices.

• Use RJ-45 Ethernet cable to connect the LAN interfaces (eth0) of the two IAG devices to the same switch, and then connect the switch to the LAN switch, connecting it to the LAN.

After the two devices are correctly wired, switch on the power for both devices and then configure them. The procedures for configuring the redundant system are the same as those for a standalone device. You need only configure the active IAG device, automatically synchronizing its configurations to the standby IAG device.
