Summary of Equipment holder extension classes
The Equipment Holder extension classes in the Telecommunications Network Inventory application allow you to define and manage various types of physical enclosures that house telecommunications and network equipment. These classes extend from the base Equipment Holder class to represent specific equipment containers such as cabinets, racks, shelves, slots, and subslots.

Key Features
- Cabinet: Represents a telecom cabinet used to securely house switches, routers, patch panels, power supplies, and other network infrastructure components in a protected environment.
- Multi Rack: Defines a multi-rack system comprising multiple interconnected racks to accommodate large volumes of telecommunications equipment centrally, supporting scalability and efficient management.
- Rack: A standardized framework for organizing and securing servers, networking devices, and storage units in data centers or technology environments.
- Shelf: Supports non-rackmount equipment within racks or cabinets by providing a stable platform for devices without built-in rackmount capabilities.
- Slot: Represents a physical or virtual receptacle for components like expansion cards or memory modules, providing standardized interfaces for hardware integration. The slot name is typically discoverable or derived from the contained card.
- Subslot: A slot located on a card that can accommodate child cards, with identification usually discovered via SNMP or named after the contained card.
Practical Use for ServiceNow Customers
By leveraging these extension classes, you can accurately model the physical infrastructure of your telecommunications network within ServiceNow. This detailed representation enables better asset management, streamlined inventory tracking, and improved planning for equipment deployment and maintenance. Understanding the hierarchy and relationships—from cabinets down to subslots—helps maintain clear visibility into how network components are organized and interconnected.
The Equipment Holder extension classes are the sub-classes that are extended from the Equipment Holder. You can define equipment holder records for these classes in the Telecommunications Network Inventory application.
| Class Name | Table Name | Extends from | Description |
|---|---|---|---|
| Cabinet | cmdb_ci_container_cabinet | cmdb_ci_equipment_holder | A telecommunications cabinet, also known as a telecom cabinet or equipment cabinet, is a physical enclosure used to house and protect various telecommunications and network equipment, such as switches, routers, patch panels, and power supplies. It provides a secure and organized environment for the installation, management, and interconnection of telecommunications infrastructure within a network or data center. |
| Multi Rack | cmdb_ci_container_multi_rack | cmdb_ci_equipment_holder | A multi-rack, also referred to as a multi-rack system or multi-rack enclosure, is a configuration consisting of multiple interconnected equipment racks used for housing and organizing a large amount of telecommunications or network equipment in a centralized manner. It provides expanded capacity and scalability, allowing for efficient deployment and management of equipment within data centers or telecommunication facilities. |
| Rack | cmdb_ci_container_rack | cmdb_ci_equipment_holder | A rack, commonly known as a server rack or equipment rack, is a framework designed to securely hold and organize various IT and telecommunications equipment, such as servers, networking devices, and storage units. It provides a standardized form factor for easy installation, organization, and maintenance of equipment in data centers and other technology environments. |
| Shelf | cmdb_ci_container_shelf | cmdb_ci_equipment_holder | A shelf holder, also known as a rack shelf or equipment shelf, is a component designed to support and hold non-rackmount equipment or devices within a rack or equipment cabinet. It provides a stable platform for equipment that does not have built-in rackmount capabilities, allowing for efficient organization and integration of various devices within the rack infrastructure. |
| Slot | cmdb_ci_container_slot | cmdb_ci_equipment_holder | In the context of technology and hardware, a slot refers to a physical or virtual receptacle designed to hold and accommodate a specific type of component, such as an expansion card or memory module. It provides a
standardized interface and location for inserting and connecting the component to the main system or device. Dependent on Hardware (contains::contained by). Name is usually discoverable. If not available,use the name of the card that is contained in this slot. |
| Subslot | cmdb_ci_container_subslot | cmdb_ci_equipment_holder | In our context, a slot that is present on a Card and can accommodate child cards is considered a subslot. Dependent on Hardware (contains::contained by). Identification: Name (100). Name is discovered from SNMP. If not available, use the name of the card that is contained in this subslot. |
