    Count Numbers of child product models that can be created under a parent product model when a template is created.
    Note:
    This attribute is only for Equipment to Slot, Rack to Slot, Equipment to Network Interface, Interface card to Slot, Interface card to Network Interface, and Logical Connection to Channel relationship types.
    Root product model Grandparent model of the interface card for compatibility. Either select the equipment model or the interface card model. Then, select the search icon (Search icon.) and select a model.
    Note:
    This attribute is only visible for the Slot to Interface card relationship type.
    Parent product model Product model that is the parent to the child product model. Select the search icon (Search icon.) and select a model.
    Note:
    In the Rack-to-Slot relationship, the parent product model is the equipment holder model with the model category as Rack.
    Child product model Product model that is the child to the parent product model. Select the search icon (Search icon.) and select a model.
    Note:
    In the Rack to Slot relationship, the child product model is the equipment holder with model category as Slot.
    Sequence

    Sequence number of the child entities for a model relationship. If you enter a number in the Count field, the Sequence field appears.

    The default value is 1. If the parent model has multiple relationships, the sequence number for the first relationship is set to 1 and the number following the highest value of the first relationship is set for the consecutive relationships. For example, let's say that your equipment has a model relationship with two slots and two ports. When the relationship is created, the sequence number of the slots and ports are set to 1 and 3.

    Note:
    This attribute is only for Rack to Slot, Equipment to Slot, Equipment to Network Interface, Interface card to Slot, Interface card to Network Interface, and Logical Connection to Channel relationship types.
    Parent bandwidth Bandwidth of the parent product model.
