Physical Interfaces: Acme Packet 4500

There are two sets of physical interfaces on the network interface unit (NIU) used in the Acme Packet 4500. These interfaces are located on the rear of the system chassis.

• Media interfaces are on the network interface unit (NIU); they are also referred to as network media ports
• Management interfaces are also on the NIU; they are also referred to as network management ports

The following picture of the NIU shows you how the network media and network management ports appear. These designations are an important point of reference when you set up phy-interface configurations. Note that the slot parameter for network management ports will always be set to zero (0).
