After summer, the proportion of temperature-related alarms in the computer room and weak current room increased significantly. Power consumption and heat dissipation are two sides of the same coin: if heat cannot be discharged, the fan is forced to rotate at a high speed, and power consumption and failure rates increase together. The summer inspection recommendations focus on three accounts.
High temperature derating: first check whether the equipment can be left in place
The operating temperatures of transceivers, optical modules and network cards are usually marked as 0 to 70°C for commercial use and -40 to 85°C for industrial use. If the temperature exceeds the nominal range for a long time, performance and lifespan will be compromised. During the inspection, first read the DDM shell temperature: the end point close to the upper limit. Prioritize the air duct, install protection, or replace the wide-temperature model, so that the reading returns to the manufacturer's name range, instead of relying on the fan hard top.
Check the power supply margin and fan working conditions together

The total power consumption margin and single-slot power supply should be checked. Poor heat dissipation will also reduce the power conversion efficiency; long-term full rotation of the fan consumes electricity and wears bearings. Collect box-type equipment scattered in weak current rooms and put them on the shelves, so that power supply, heat dissipation and inspection can all be handled in one place.
It is recommended to keep these three sets of numbers for inspection records
- Check the inlet air temperature and hot spot location of each cabinet, indicate the measurement height and time point, and measure once in the morning and evening;
- The transmitting and receiving luminous power and case temperature baseline of key links, summer values and spring values are archived separately to identify drift with temperature;
- Fan speed and alarm times are used to identify cabinets that have been running at full speed for a long time, and priority is given to dealing with obstructions and dust accumulation.
After three sets of data are accumulated for two summers, it can be seen which cabinets are on the edge of heat all year round, providing a basis for equipment replacement and layout adjustment.
