Field	Description
Power (watts)	Electrical power of the network asset in watts.
Sound power (bels)	The rate at which the energy of the network asset is emitted in bels. Note: This field is applicable for all types of models except the network interface models.
CLEI code	Assigned Common Language Equipment Identification (CLEI) for this network asset. CLEI codes are globally unique, 10-character alphanumeric intelligent codes that identify the equipment in a structured naming format. There’s a one-to-one relationship between a CLEI code and a manufacturer's product code, which is a part number that includes the hardware version. Note: This field is applicable for all types of models except the physical connection models, the logical connection models, and the network interface models.
Connector type	Type of physical cable connector that is used for the connection of the cable to the network interface. Select one of the following options: BNC SC LC ST Wire Wrap RJ45 Note: This field is only applicable to Network interface models.
Height (U)	Number of rack units required for the model. Note: This field is only applicable to the equipment models.
Slot naming pattern	Name patterns that are used to define the names that are generated for the slots and interfaces that are on the equipment or card. Because these name patterns are at the model level, they’re applied by default to every template of that model. These name patterns are editable for the different instances of the same model. To learn more about the naming convention, see Naming convention for associated templates. Although the names are generated automatically, you can manually edit the names of the templates. Note: This field is applicable for the equipment models and the interface card models. The generated name remains empty if the following occurs: The variable names are misspelled. You use the parent_slot or equipment_slot information for the interfaces or slots that are in the equipment. If this field is left empty, then the default naming pattern is considered. Here, the default naming is Slot-001, where 001 is the slot start number. This field is applicable for the equipment models and the interface card models.
Slot start number	The first number to assign to the slots in this model. The slot names are generated automatically depending on the starting number. Note: The entered value doesn’t affect the unit position. The unit position always starts from 1 and is used in the slot naming pattern. This field is applicable for the equipment models and the interface card models.
Slots occupied	Number of slots that are occupied in the card. Note: This field is only applicable to the interface card models.
Length	Length of the network asset, expressed in the unit of measure that you designate in the Units field. For example, enter `12` if the asset is one foot, or enter `60` if the asset is 60 inches and you've selected `Inches` as the unit of measure in the Units field. The ServiceNow AI Platform uses this information to calculate the cubic dimensions of the asset to determine its physical placement within the designated network site.
Measurement unit	Unit in which the physical dimensions of the asset are measured. Note: This field is applicable for the equipment models, the equipment holder models, and the physical connection models.
Width	Length of the network asset, expressed in the unit of measure that you designate in the Units field. For example, enter `12` if the asset is one foot, or enter `60` if the asset is 60 inches and you've selected `Inches` as the unit of measure in the Units field. The ServiceNow AI Platform uses this information to calculate the cubic dimensions of the asset to determine its physical placement within the designated network site. Note: This field is applicable for the equipment models and the equipment holder models.
Height	Height of the network asset, expressed in the unit of measure that you designate in the Units field. For example, enter `60` if the height of the asset is 60 inches and you've selected `Inches` as the unit of measure in the Units field. The ServiceNow AI Platform uses this information to calculate the cubic dimensions of the asset to determine its physical placement within its designated network site. Note: This field is applicable for the equipment models and the equipment holder models.
Depth	Depth of the network asset that is expressed in the unit of measure that you designate in the Units field. Note: This field is applicable for the equipment models and equipment holder models.
Interface start number	Starting number that you assign to the interfaces of the equipment or the card. For example, if the starting number is 10 for 20 interfaces, then the interface numbers start from 10, such as Port-010, Port-011, and so on to Port-029. Note: The interface numbers are generated automatically based on the entered value. The unit position isn’t affected. The unit position always starts from 1 and is used in the interface naming pattern. This field is applicable for Equipment models and Interface card models.
Enable Interconnect	Option that you can select so that all the interfaces on the equipment are interconnected to each other. Note: The default algorithm for the interconnection is `(N/2) +1`, where `N` is the total number of interfaces on the equipment, is applied. For the odd port numbers, the system takes `N` as the previous number `(N-1)` and creates the interconnections. For example, let's say that you have a piece of equipment that has 10 interfaces. If you select this option, the first interface is interconnected with the sixth interface, 2–7, 3-8, 4-9, and 5–10. This field is only applicable to the equipment models. All the created interconnections are listed as a configuration item (CI) relationship.
Interface naming pattern	Name patterns that are used to define the names that are generated for the slot and Interfaces on the equipment or card. Because these name patterns are at the model level, they’re applied by default to every template of that model. These name patterns are editable for the different instances of the same model. To learn more about the naming convention, see Naming convention for associated templates. Although the names are generated automatically, you can manually edit the names of the templates. Note: This field is available only for Equipment models and Interface card models. The generated name remains empty if the following occurs: The variable names are misspelled. You use the parent_slot or equipment_slot information for the interfaces or slots that are in the equipment. If this field is left empty, then the default naming pattern is considered. Here, the default naming is Port-001, where 001 is the interface start number. This field is available only for the equipment models and interface card models.
Orientation	Physical orientation of the slots in this network asset: --None-- No specific physical slot orientation. Horizontal Horizontal slot orientation. Vertical Vertical slot orientation. Note: This field is only applicable to the equipment holder models.
Virtual	Option to verify whether the network interface is physical or virtual. Note: If you select Virtual, then the Connector Type field doesn’t appear. This field is applicable only for Network interface models.
