– Cascade: The number of operating devices varies depending on the
thermal load in equipment room to meet requirements promptly,
eliminate hot spots, and save energy.
– Anti-competitive operation: A mechanism is adopted to prevent devices in
the same equipment room operating in opposite status, in order to save
energy.
– Self-teamwork control: If one of the communications cables in the
teamwork network is disconnected, two teamwork networks are formed.
Devices without a master can automatically determine the master one
and continue teamwork control.
Remote management: You can monitor and manage one or more devices
using the remote management function provided by Huawei.

Password verification is required upon the first startup to ensure the system
security. No password verification is required for subsequent startup if the first
verification succeeds.
The controller provides functions such as automatic recovery after power
failure and water leakage detection, improving the system reliability.
The cooling capacity, air volume, as well as the operating status and time of
each component in the device are displayed on the LCD in real time.
The controller provides abundant external ports such as FE ports, CAN ports,
RS485 ports, and USB ports that are protected by a security mechanism.
These ports flexibly meet the communication requirements and feature good
electrical isolation.
Information can be displayed on the LCD in twelve languages: Chinese,
English, French, Spanish, Russian, Turkish, and so on.
The O&M personnel can export fault records in one-click mode, making it
easy to operate the device and learn the running status of the device.
The device supports communications protocols such as Modbus RTU, Modbus
TCP, and SNMP, facilitating connection to the network management system.
