Liebert Intelligent Cabinet System：
In the late 70s, enterprises began installing computers in cabinets. However, due to incompatibility between equipment from multiple suppliers,
installation was difficult. In 1984, the International Electrotechnical Commission (IEC) adopted the IEC297-3 standard, specifying the standard physical dimensions of cabinets as 482.6nun (lgin).
Other standards, such as EIA310 (Electronic Industries Alliance), further established standards for rack-mounted telecommunications and IT equipment.The vertical mounting posts can be easily adjusted to meet the requirements of equipment with different installation depths.Quickly removable front and rear doors and side panels. Removing cabinet doors or side panels during equipment installation and daily maintenance provides unexpected convenience.

Liebert Intelligent Cabinet System：
Cabinet bodies that meet modern core computer room design requirements typically have the following characteristics.

Liebert Intelligent Cabinet System(1) The ventilation area of the front and rear doors is not less than 5355cm2, meeting the ventilation requirements specified by major server manufacturers.

Cabinet front door meeting ventilation area requirements

Liebert Intelligent Cabinet System(3) All equipment compliant with the EIA-310-D standard can be correctly installed.

(4) Integrated rear cable management channels allow users to easily route, manage, and operate large quantities of data cables, even when rack equipment is already installed or cabinets are joined together.

Liebert Intelligent Cabinet System(5) Through the rear power distribution channel, users can easily install various models of vertically mounted Power Distribution Units (PDU) without occupying valuable effective installation space in the cabinet. The dedicated power distribution channel facilitates power distribution operations, while

providing a greater number of power sockets for equipment installed in the cabinet. The power distribution channel on one side of the cabinet can provide no fewer than 21 IEC power sockets.

(6) Power cables and data cables can come from the overhead cable trays above the cabinet or from the underfloor space, so sufficient cable entry ports must be provided at the top and bottom of the cabinet. In some usage environments,
power or data cables may need to be routed from one cabinet to an adjacent one in a row. Side cable entry ports must be provided in the rear cabling channel to meet this requirement.

Liebert Intelligent Cabinet System(7) Each "U" position is clearly marked on the vertical mounting posts of the cabinet, eliminating the trouble of repeatedly searching for installation positions and greatly facilitating user installation work.

(8) The front door, rear door, and side panels can all be locked and opened only with the provided keys.

(9) The verified frame design, robust standard mounting posts, and heavy-duty casters provide static and dynamic load ratings of no less than 900kg.

Liebert Intelligent Cabinet System(10) Multiple grounding bolts are provided to offer sufficient grounding points for equipment installed inside the cabinet and all independent metal components.
