Monitoring System
The full liquid cooling cabinet uses an independent cabinet control unit (CCU) to monitor the liquid cooling system. The monitoring system provides the following functions:
- Temperature/humidity monitoring
Perform temperature/humidity monitoring only when the water inlet temperature on the primary side is +3°C lower than the dew point (DP) temperature of the equipment room.
- Monitoring of water leakage from the manifolds, air/liquid heat exchanger, and secondary side
- Access control monitoring
- Control of the manifold solenoid valves.
This option is not configured by default. It is configured when required by the customer.
- Control of solenoid valves of the air/liquid heat exchanger
This option is used with temperature/humidity monitoring. It is configured only when the water inlet temperature on the primary side is +3°C lower than the DP temperature of the equipment room.
- Software upgrade (using SSH)
- The FE port is used to connect to the NMS and supports the SNMPv3 protocol.
