(If you want to hear more of your voices, and want to receive more of your suggestions, search for the WeChat public account "qdread" now and pay attention to it, and give more support to "Super Telecom Empire"!) Obviously, the technicians of the county post and telecommunications bureau still have some skills, although they have not seen the process control switch, but they have plugged all the functional boards in the right place with English instructions and their own telecommunications common sense, just because no one has helped them check, they dare not plug in the end and lock it.

And the inside of the switch has also been cleaned up by them, and the power cables and user cables are organized in an orderly manner.

Jiang Xinwei did not immediately turn on the switch, but turned on the power of the computer used to manage and control the switch. The black-and-white display quickly showed some English characters, and then a flashing cursor appeared in the top left corner.

For others who are accustomed to using graphic operating systems and mouse operations, they must be a little at a loss for this kind of computer that needs to enter the name of the executable program, but for Jiang Xinwei, who has been engaged in telecommunications equipment research and computer control technology research for a long time, there is a kind of comfort of reuniting old friends.

Seeing the cursor flickering on the screen, he quickly typed in a display command LIST. After the computer quickly displayed a series of text names, he immediately entered the batch program name at the cursor flashing below.

In Guo Qian's surprised and Zhu Jianhua's expression of "I knew he was so powerful", the computer began to run rapidly, and the host chassis made a buzzing sound.

Soon, the black and white display of the computer shows an interface based on large and small English letters, with the name and logo of the switch manufacturer, as well as the product version number and rights statement, and welcome message.

This screen lasted for about five seconds, and immediately entered a login screen, where an input box appeared in the center of the shield, prompting the user in English to enter their username and corresponding password.

If it is the first time to use this software system, you will be at a loss when you see this input box, just like the technician of the county post and telecommunications bureau, you must know the relevant user name and corresponding password to carry out the following work. The reason why they didn't go back to debugging the switch was because they didn't know what username and password to enter at this step.

However, Jiang Xinwei knows that this level is just bluffing, and the original intention of setting it up is not to prevent someone from logging in by mistake, nor is it to prevent the wrong person from logging in to cause damage, but to give the manager a future management authority: he can enter it generously, and then configure the rights of each login person in the management and use rights function module.

Since the manager can enter it generously, the user name and corresponding password should be public or commonly used, or the default or universal user name and password are set when the product leaves the factory.

Yes, this level is usually a fictitious one, and it is a common username and password. Jiang Xinwei has dealt with many communication equipment manufacturers in his last life, and remembers the general usernames and passwords of many manufacturers, and knows that the usernames and passwords of this kind of switch in front of him are Administrator, and the English letters can be uppercase, lowercase, or a mixture of uppercase.

The reason why the technicians in the county bureau didn't know was because they hadn't come into contact with the Yankees' program-controlled switches.

In the next few years, when a large number of foreign switches are imported from China, almost all professional telecommunications personnel will only regard these as a kind of common sense, for example, many brand switches in the United States set the username and password as Administrator. However, many switches produced in Germany set the username and password to system001 when they leave the factory.

This is all public information, to put it bluntly, worthless, but it is a barrier to people who have not been exposed to these devices in this era, and it cannot be carried out here.

Jiang Xinwei entered the Administrator in turn, and soon the screen interface changed, turning into a horizontal bar menu, on which each functional unit was displayed with bar boxes, which were "hardware configuration", "number jù configuration", "phone bill management", "permission management", "fault diagnosis", and "help".

Seeing this interface appear, a series of little stars appeared in Guo Qian's eyes, and she blurted out, "Master Jiang, you actually know the Yankee's password?...... You...... You know this kind of foreigner's switch better than the technician of the county post and telecommunications office?"

Before Jiang Xinwei could answer, Zhu Jianhua next to him said: "Of course, what are they? Even Director Xu of the Municipal Telecommunications Bureau admires Master Jiang, can these people make the director of the Municipal Bureau admire?"

Jiang Xinwei smiled and said, "I just happened to know this general password." When the product leaves the factory, the Yankees often set this. However, after the switch is debugged and activated, the administrator will set them to their favorite or easy-to-remember username and password, and I can't get in at that time. ”

In fact, he can still enter, and it is not difficult for him to crack the program code of this era when he is proficient in switch technology.

Guo Qian also wanted to ask him why he knew but the people from the county post and telecommunications bureau didn't, but when he saw that Jiang Xinwei had already moved his cursor to the box of "hardware configuration", he stopped talking, and stared intently at what he was doing.

She didn't know that if she really asked that sentence, she would stump Jiang Xinwei for the first time, because it was difficult for him to answer and explain what he said in his mouth "coincidence".

The so-called hardware configuration is actually the system to confirm which circuit boards are installed in the switch, or ask the administrator to clarify which circuit boards of the switch are ready for immediate operation. After all, although this small switch is small, it can also accommodate 256 telephone users, while ordinary small factories and mining enterprises rarely need so many users, and there must be a lot of redundant user circuit boards, and some user boards are not necessary to open for the time being.

Turning on useless circuit boards not only wastes power, but also reduces their lifespan and increases the point of failure.

Using the "hardware configuration" function, in addition to shielding those circuit boards that do not need to be turned on and preventing them from generating unwanted alarms, Jiang Xinwei can also use this function to check whether the position of the circuit board plugged into the current switch is correct.

He pointed to the circuit board configuration diagram displayed on the screen with his finger, and explained to Guo Qian and Zhu Jianhua: "Look carefully! Compare this diagram with the actual switch to see if the circuit board of the switch is plugged in correctly? The first circuit board model in the first row above is AD002-01, can you see if it?"

Jiang Xinwei's purpose in entering the computer room today to see the switch is naturally to understand the current situation of the switch and prepare for his future production of the switch, and the other purpose is to help Guo Qian and Zhu Jianhua learn some modern switch technology. Although their diplomas are not high, they are only high school graduates and high school students, but as long as they take them seriously to learn, they have no problem becoming ordinary technicians, and it is completely okay to let their technology surpass most telecommunications technicians who have not been exposed to process control switches, at least they can make their operation ability surpass other technicians.

The two of them listened to Jiang Xinwei's instructions, and hurriedly put their heads on the switch to look, and sure enough, they saw the relevant model in the corresponding position of the switch circuit board.

"That's right! It's AD002-001!" Zhu Jianhua said loudly, looking proud.

Jiang Xinxu said: "The Chinese name of this board is the user board, and the user cable is connected from the back of it, connected to the distribution frame in the computer room, and connected to the telephone outside in the guò user line." Its main functions are current overvoltage protection, providing ringing signals to the telephone, and monitoring the status of the telephone, such as whether the phone is being connected, dialing, or standby, and these status signals are sent to the switch's control circuit board at any time......"

He knew that it was useless to give them a lot of knowledge at once, and that they would not only be unable to remember it, but would also be afraid of difficulties. Therefore, he only decided to talk about the functions of the user board and the power supply board today, because these two types of circuit boards are easy for them to understand, not to mention that they have been on duty in the computer room for a long time, and they know what the user line and patch panel are, and they also know what the power supply is, even the average middle school student can quickly understand it, and there is no pressure to learn.

He deliberately slowed down and spent about ten minutes having them double-check all the boards on the switch against the hardware configuration diagram on the computer, and confirmed that all the boards were inserted in the correct position.

After confirmation, Jiang Xinwei asked Zhu Jianhua to power on the switch.
