42U Integrated Micro Data Center Cabinet

An integrated micro data center is a factory-built IT room in a cabinet footprint. It combines the rack, cooling, UPS, power distribution, fire suppression, access control and environmental monitoring in one enclosure, so the site only needs a power feed, a network connection and a prepared floor.

It is used for edge computing, branch offices, hospitals, factories, retail sites and small research labs where a traditional computer room is too large or too slow to build. The 42U frame provides 1,866.9 mm of mounting height for servers, storage and network equipment.

A single-cabinet unit is typically 600 mm wide, 1,200 mm or 1,400 mm deep and 42U high. A 1,200 mm deep unit suits standard servers; 1,400 mm gives more room for rear cooling and cabling. Multiple cabinets can be joined into a 2-cabinet or 4-cabinet pod with a shared cooling and power module.

Cooling capacity is commonly 25 kW to 50 kW per pod, using rack-mounted or row-level air conditioners. The actual IT load depends on the server configuration; confirm the heat load, the redundancy level and the ambient conditions before selecting the cooling unit.

The integrated UPS is usually a modular or tower unit rated from 10 kVA to 30 kVA, with N+1 module redundancy or a 2N configuration for critical sites. Battery runtime is typically 10 to 30 minutes at full load, using VRLA or lithium batteries in a dedicated cabinet.

Power distribution includes input breakers, a maintenance bypass, metered PDUs and surge protection. For sites with unstable power, add an automatic transfer switch and a generator interface. Confirm the input voltage, frequency and earthing system for the destination country.

Fire protection typically uses a clean-agent suppression system with smoke and heat detectors. The cabinet is sealed to hold the agent, and the system is interlocked with the power supply. Access control can be a card reader, keypad or biometric lock, with door alarms and audit logs.

Monitoring covers temperature, humidity, water leakage, smoke, power quality and door status. A local touchscreen shows the live status; remote access uses SNMP, Modbus or a web portal. Alarms can be sent by email, SMS or a monitoring platform.

The unit is assembled, wired and tested in the factory before shipment. Testing includes power-on, UPS transfer, cooling start-up, alarm simulation and leak checks. The cabinet ships as a single unit where the access route allows; otherwise it is split into modules for site assembly.

Typical lead time is 30 to 45 working days after drawing approval, depending on the cooling and UPS configuration. Site work includes positioning, power connection, network connection, water or condensate drain (for some cooling units), commissioning and operator training.
