Conduct various inspections before power outage
1. Open the control station cabinet door and observe if the card is working properly and if there are any fault displays;
2. Observe and record the existence of faults from the real-time monitoring fault diagnosis of each operating station;
3. Check whether the power box works normally, whether the power fan works, whether the 5V and 24V indicators are normal, measure and record the voltage values;
4. Backup configuration, PID parameters, drivers, and other necessary important data;
5. Check the power supply redundancy, which includes AC power supply redundancy and DC power supply redundancy. AC power supply redundancy: By disconnecting one of the redundant AC~220VAC incoming lines, half of the AC power supply circuit of the system loses power, but the system should still be able to operate normally. The redundancy testing method for DC power supply is as follows:
(1) Firstly, disconnect one power supply box and measure the voltage of 5V and 24V on the power terminals of each cage and cage motherboard;
(2) First connect one power supply box, then disconnect the other power supply box, and then measure the voltage of 5V and 24V on the power terminals of each cage motherboard. The 5V output voltage of the power box should be between 5.10V and 5.25V, and the 24V output voltage of the power box should be between 23.00V and 25.00V. If the voltage deviation is large, it needs to be checked and handled in a timely manner, otherwise it will affect the normal operation of the card.
6. Check the network cable and layout, check the connection and disconnection of the network cable, confirm whether the connection is in good contact, and replace the faulty cable in a timely manner;
7. UPS test: Test the power supply capacity of the UPS battery by disconnecting the UPS AC incoming line. UPS batteries should be discharged regularly, generally recommended once a month. Discharge method: Disconnect UPS AC power supply and use battery power until the battery is about to be discharged.
The above checks mainly focus on understanding the operating status of the system in advance. If there are any abnormal phenomena, they can be promptly resolved during parking.
