Preparing the new HA1 appliance

Follow these steps to prepare the new HA1 appliance.

1. Power up the new HA1 appliance and attach the supplied serial console cable to the console port.
2. Configure the new appliance and set up ETH13, ETH17, and ETH21 to have the same configuration as the HA1 appliance that you are replacing. See Configuring Ethernet interfaces by using the command line for help with configuring the Ethernet ports.
   Note: If you configured your original HA group to use a custom interface for replication, then you should use the same interface for your new appliance. See Configuring custom HA replication interfaces.
3. Configure the MGT0 port. Connect the port to a 1 Gb network, and configure it with the same details that the appliance you are replacing was configured. (This connection enables you to send commands to the appliance from a remote workstation.)
4. Configure the remaining Ethernet ports as they were originally configured for the main appliance.
5. Connect the new HA1 appliance to the existing HA2 appliance, as specified in the following table:

   HA1 Appliance	HA2 Appliance
   ETH21	ETH21
   ETH17	ETH17
   ETH13	ETH13

6. Make other network connections as required to replicate the configuration of the original HA1 appliance.
7. Check the 1 Gb and 10 Gb connections by ensuring that the HA1 appliance can ping the HA2 appliance and vice versa.
