First, switch LED display notes 1. Switching sequence: When opening the screen: first boot, then open. When closing the screen: first turn off the screen, then turn off the screen. (The computer does not turn off the display first, which will cause the screen to appear bright, burning the lamp, the consequences are serious.) 2. When switching the LED display, the interval time should be greater than 5 minutes. 3. After the computer enters the engineering control software, it can be powered on. 4. Avoid opening the screen in the full white screen state because the system has the largest inrush current. 5. Avoid opening the screen in the out of control state, because the system has the largest inrush current. (A) The computer does not enter the control software and other programs; (B) the computer is not powered; (C) The control section is not turned on. 6. When the ambient temperature is too high or the heat dissipation conditions are not good, care should be taken not to open the screen for a long time. 7. When a part of the LED display body appears very bright, you should pay attention to closing the screen in time. In this state, it is not suitable to open the screen for a long time. 8. The power switch of the display often trips. Check the screen or replace the power switch. 9. Regularly check the tightness of the hook. If there is looseness, pay attention to timely adjustment, re-reinforce or update the hanger. 10. According to the environment of the display body and control part, avoid insect bites and place anti-rat medicine if necessary. Second, control part changes, changes notice 1. The power cord of the computer and control part is zero and the fire cannot be reversed. It should be inserted exactly in the original position. If there are peripherals, after the connection is completed, the chassis should be tested for power. 2. When moving the computer and other control equipment, first check the connection line and the control board for looseness before power-on. 3. The position and length of the communication line and flat connection line cannot be changed at will. 4. If abnormalities such as short circuit, tripping, burning line, and smoke are found after moving, the power should not be tested repeatedly. The problem should be found in time.
FTTH Fiber Optic Socket Terminal Box, fiber termination box provides a mini density wall-mounted solution for next generation networks, which aims to provide and manage minimum numbers of fibers in a limited space.
