To set up HA for your QNE devices, you must prepare the following items.

• Two QNE devices with the following identical specifications and components:

  • Device model

    Note:

    HA Manager currently supports QuCPE devices only.

  • Firmware version

  • CPU model

  • Memory capacity

  • Application disk specifications

  • Network module model

  • Number of power supply units

  • At least one 10 Gigabit or greater network port

• One 10 Gigabit or greater network cable

  Note:

  • This cable connects the HA link ports between the QNE devices.

  • Both QNE devices must have the same HA link port number.

  • The HA link allows data detection and synchronization from the active node to the standby node.

• Two network cables

  Note:

  • These cables connect the management port of each QNE device to the network. The management port allows you to access and manage the active node and standby node devices.

  • For each device, you must configure a static IP address for the management port. You can configure the static IP addresses during HA configuration.

  • Both QNE devices must have the same management port number.

• Optional: Virtual IP address

  Note:

  Setting up a virtual IP address allows you to maintain a constant connection to the active node no matter which device becomes the active node after a failover or switchover.
