Motherboard Ports

Although the Ethernet ports on a bypass card are inaccessible when the bypass relay is closed, the motherboard ports remain active. You can sometimes access a failed appliance through the motherboard ports if the bridged ports are inaccessible.

The Primary Port

If the Primary port is enabled and has an IP address assigned to it, the appliance uses that IP address to identify itself to other acceleration units. This address is used internally for a variety of purposes, and is most visible to users as the Partner Unit field on the Monitoring: Optimization: Connections page. If no motherboard port is enabled, the appliance uses the IP address of Accelerated Pair A.

The Primary port is used for:

  • Administration through the web based UI
  • A back channel for group mode
  • A back channel for high-availability mode

The Aux1 Port

The Aux1 port is identical to the Primary port. If the Aux1 port is enabled and the Primary port is not, the appliance takes its identity from the Aux1 port’s IP address. If both are enabled, the Primary port’s IP address is the unit’s identity
