Network inventory facility classes

The facility classes are used to represent power, HVAC, network, and their connectivity in a data center. You can define facility hardware records for these classes in the Telecommunications Network Inventory application.

表 : 1. Equipment Holder extended classes

Class Name	Table Name	Extends from	Description
Transformer	cmdb_ci_transformer	Power Equipment	Transformers change the voltage of alternating current (AC) in a power distribution system. You will find them in data centers and other power generation, transmission, and distribution networks. They either increase or decrease voltage levels for efficient transmission and safe power distribution.
Switch Gear	cmdb_ci_switch_gear	Power Equipment	Switchgear helps manage and protect your electrical circuits in a telecom data center. It's key for safe, reliable power distribution.
Power Panel	cmdb_ci_power_panel	Power Equipment	A Power Panel, often referred to as a power distribution panel or electrical panel. Power panels efficiently and safely manage and distribute electrical power to circuits and devices.
Rectifier	cmdb_ci_rectifier	Power Equipment	Rectifiers are essential for converting AC power to DC power. Your telecom and networking equipment rely on stable DC electricity.
Maintenance Bypass Panel	cmdb_ci_maintenance_bypass_panel	Power Equipment	A maintenance bypass panel (MBP) is an important part of your electrical power system, especially if you work with data centers. It lets you maintain or replace power equipment, like a UPS, without turning off power to other equipment. This is important to keep things running smoothly when you make updates.
Remote Power Panel	cmdb_ci_remote_power_panel	Power Equipment	A Remote Power Panel (RPP) distributes power in data centers to devices or other loads from a central source like a UPS or generator. They're useful for managing power in server racks and IT equipment.
Inverter	cmdb_ci_inverter	Power Equipment	An inverter takes the DC power from your telecom data center and changes it to AC power. While most telecom equipment uses DC power, you will need AC power for systems like air conditioning, lights, servers, and some monitoring devices.
Circuit Breaker	cmdb_ci_circuit_breaker	Power Equipment	Circuit breakers protect your telecom data center from overloads, short circuits, and equipment failures. They automatically disconnect the power supply when something goes wrong to prevent damage, fire, or downtime.
Fuse Alarm Panel	cmdb_ci_fuse_alarm_panel_function	Power Equipment	A Fuse Alarm Panel is a critical component in a telecom data center’s DC power distribution system. It serves two main purposes: Distributes DC power to various telecom loads (like routers, switches, and other network equipment). Monitors fuse status and triggers alarms when a fuse blows, enabling quick fault detection and response.
Rack Rail	cmdb_ci_rack_rail	Hardware	A rack rail is a mounting structure inside a telecom or server rack that allows you to securely install, support, and slide equipment such as servers, switches, power supplies, and other hardware into place.
Wire Manager	cmdb_ci_wire_manager	Hardware	A wire manager (also called a cable manager or cable management system) is a device or accessory used to organize, guide, protect, and secure network and power cables within telecom racks and data center infrastructure.
Cage	cmdb_ci_cage	Facility Hardware	A cage in a telecom data center is a secure, enclosed physical space within a larger data hall or colocation facility, built using metal mesh panels and lockable doors. It is used to isolate and protect a customer’s or department’s servers, telecom gear, and networking equipment from unauthorized access.
Rack PDU	cmdb_ci_rack_pdu	PDU	A Rack PDU (Power Distribution Unit) is a critical component used in data centers and server rooms to distribute electrical power to multiple devices housed within a server rack. It serves as a centralized power management solution, ensuring reliable and efficient power delivery to IT equipment such as servers, switches, routers, and storage systems.
