In an HA configuration, the two SBC 5400 platforms are connected to each other with two 1 Gb/s HA links. The connection provides box-level redundancy.
Each of the HA peer SBC 5400 platforms has four management ports with their own addresses, and these platforms can each be controlled through these addresses whether the platform is currently in an Active or Standby state. Additionally, the user can assign a Logical Management address to the HA pair (refer to Configuring Logical Management Interfaces). The user can control the Active HA peer through this Logical Management address and When switchover occurs, the logical management address follows the currently active server.
For the media ports, the MAC and IP addresses float between the HA pair (are replicated from Active to Standby on HA peer switchover).
Connect HA cables between the HA pair as shown:
Active HA0<--------->Standby HA0
Active HA1<--------->Standby HA1
