[0026] figure 1 It is a schematic diagram of the communication device provided by the first embodiment of the present invention, which is represented by figure 1 It can be seen that, in this embodiment, the communication device 1 provided by the present invention includes: a main control board 11, a fixing device 12 and a storage device 13, wherein,

[0027] The main control board 11 refers to a single board for realizing the main functions and control of the communication device 1, the fixing device 12 is used for fixing the main control board 11, and the storage device 13 is used for storing configuration information of the communication device 1;

[0028] The storage device 13 is arranged on the fixing device 12 , and when the communication device 1 is started, the processor in the main control board 11 reads the configuration information and guides the main control board 11 to start up.

[0029] The present invention realizes the separation of the storage device 13 and th...

[0040] In this embodiment, the communication equipment includes only one main control board, the storage device is an electronic barcode chip, and the fixing device is a backplane. figure 2 Shown:

[0041] The electronic barcode chip is fixed on the backboard, the protection device is set on the main control board, and its power supply is provided by the main control board. In order to improve reliability, the main control board adopts an overcurrent protection chip 21 to realize power supply control, so as to realize the function of the overcurrent protection circuit. The overcurrent protection chip can use chips such as MAX1607 and TPS2401. These chips have enable pin control The output of the power supply can automatically cut off the power supply in case of overcurrent to prevent the chip from burning.

[0042] For the I2C signal communicated between the electronic barcode chip and the main control board, an I2C hot-swap control chip 22 is added on the main control board...

[0045] In this embodiment, the communication equipment includes only two main control boards, the storage device is an electronic barcode chip, and the fixing device is a cabinet. image 3 Shown:

[0046] The protection device is arranged on the main control board, and the communication equipment includes two protection devices. Each protection device includes an overcurrent protection circuit (using an overcurrent protection chip 21) and a current sharing circuit to prevent the two main control boards from The mutual influence of the power supply when the boards are all plugged in, because the working current of the electronic barcode chip is relatively small, the current equalizing circuit can be realized by using a diode 31 with a low voltage drop.

[0047] The I2C hot-swap control circuit adopts the figure 2 The same I2C hot plug control chip 22 is used for protection. The enabling pins of the power overcurrent protection chip 21 and the I2C hot-swap control chip 22 are a...

Abstract

The invention provides a communication apparatus and a start method thereof. The communication apparatus comprises a main control board, a fixing device used for fixing the main control board, and a storage device used for storing the configuration information of the communication apparatus, wherein the storage device is arranged on the fixing device. When the communication apparatus is started, a processor in the main control board reads the configuration information to guide the main control board to start. According to the invention, the storage device, such as an electronic bar code chip, is arranged on the fixing device, such as a back plate and a cabinet, in the communication apparatus, and when a single plate is replaced and the communication apparatus is not replaced, the fixing device can mark the communication apparatus uniquely, so that the configuration information in the communication apparatus is fixed and unique and does not change along with the replacement of the single plate, the problem that configuration information stored in a new single plate is different from configuration information stored in an old single plate because of replacement of the single plates is solved, the replacement of the single plates does not cause the change of configuration information, and fault maintenance time is reduced.

Description

technical field [0001] The present invention relates to the field of communication equipment, in particular to a communication equipment and a starting method thereof. Background technique [0002] After the communication equipment leaves the factory, the manufacturer or operator assigns configuration information such as serial number, MAC address, and IP address to it. Such information is usually stored in a read-only memory called an electronic barcode, such as EEPROM (Electrically-Erasable Programmable Read- Only Memory, electronic erasable rewritable read-only memory) chip, this type of chip is also called electronic barcode chip, which communicates with the processor through the I2C interface. When the communication device starts, the processor obtains the necessary information from the electronic barcode chip. Configuration information guides the startup of the single board; and when the single board leaves the factory, the processor and the electronic barcode chip are...
