(Ⅰ) Cabinet status detection function: Temperature and humidity detection: Equipped with temperature and humidity sensors, it collects local display temperature and humidity in real time, and uploads the temperature and humidity conditions in the cabinet; if the temperature in the cabinet is too high, a high temperature alarm is uploaded. Cabinet door status detection: Real-time detection of cabinet door status, illegal opening of the cabinet door and alarm; after the cabinet door is opened, an open door alarm is reported. Smoke status detection: Detect whether there is smoke in the cabinet in real time. When there is smoke in the cabinet, a smoke alarm will be uploaded. Flood status detection: Real-time detection of whether there is water in the cabinet. When there is water in the cabinet, a flood alarm is uploaded.

(II) In-box equipment detection function: Lightning protector status detection: Real-time detection of the status of the lightning protector. 220V strong current detection and monitoring: Real-time monitoring and uploading of voltage status. When the mains power is cut off, a mains power cutoff alarm is uploaded. Battery pack detection and monitoring: Real-time monitoring and uploading of voltage status. When the battery pack voltage is too low, a battery pack voltage low alarm is uploaded. Equipment status detection: Read the data of 4-channel equipment through RS485 or RS232 and upload the data to the data center.

(III) Remote control function: Temperature control: can remotely control the start and stop of the waterless air conditioner. Fan control: The fan can be started and stopped remotely. Light control: The light switch can be controlled remotely. Circuit breaker control: Remote power outage and restart are possible. Reset control: System reset can be controlled remotely.

(6) ODF optical distribution unit

Integrated 12-core, 24-core, 36-core, 48-core, 72-core, 144-core, 288-core, 576-core FC-FC dispatching rack, used for terminating external optical cables and terminating equipment-side pigtails.

(7) Uninterruptible inverter power supply

The cabinet is equipped with a 2KVA/3KVA/6KVA uninterruptible inverter power supply to power the equipment. Features of UPS power supply:

(Ⅰ) Pure sine wave output, zero conversion time, effectively ensuring the reliability of uninterrupted operation of the load.

(II) CPU microprocessor control, inverter power system self-diagnosis and self-protection, greatly extending the service life of the UPS.

(III) Intelligent management, automatic data storage can be realized when the mains power fails.

(IV) Battery online management greatly extends battery life and protects user investment.

(Ⅴ) DC start-up, no mains power is required and the battery can be used to start the UPS and load machines

(VI) All-weather EMI/RFI filter prevents data errors caused by noise.

(Ⅶ) Can be used with a generator to effectively purify the bad power generated by the generator.

(VIII) Using SPWM pulse width modulation technology and IGBT power module, it has strong anti-interference and pure output waveform.

(Ⅸ) Charging speed is fast, and the long-term machine can provide an initial charging current of about 5-10A. (10) Green and environmentally friendly power supply, the input power factor is as high as 95% or more, avoiding pollution to the power grid.

(8) Cabinet lighting

Each independent cabin is provided with a set of 48V/220V LED lighting, which can be turned on when the cabinet door is opened.
