1. With the improvement of hardware channel functions, the power consumption also increases. The weight of the heat dissipation system fixed on the CPU card will inevitably increase, resulting in an unstable center of gravity of the CPU card, which is easy to cause problems such as deformation, wire breakage, and poor touch of the CPU card, resulting in unstable work.
2. In the traditional PICMG 1.0 standard, the physical connection between the CPU card and the bottom plate is the gold finger connection method, and the touch method between the gold finger and the passive base plate slot is the extrusion of the shrapnel on both sides, which is instantaneously poor in the process of oscillation and impact, causing the system to crash.
3. After the CPU card is connected to the baseplate slot, more than 50% of the surface of the gold finger is exposed to air, and it is easy to oxidize or corrode when used in a humid or corrosive gas environment for a long time, resulting in a poor touch of the system.
4. The applicable goal of the PCIMG1.0 standard is to choose the channel of AT power supply, with the diversification of market demand, more and more manufacturers require the bus to extend the support for AT/ATX dual power supply mode.
5. The PCI standard supported by the PICMG 1.0 standard is version 2.0, which cannot meet the power supply of the PCI expansion card with wake-up function to the system channel. In addition, PICMG 1.0 does not support the SMBUS bus, which makes the bus lack flexibility in the communication method of the motherboard to handle each expansion subcard.
6. As a complete system, the motherboard has multiple monitoring signals that need to be connected to the boards installed on the front or rear panels of the chassis. In line with the traditional PICMG1.0 standard of the whole machine system, the method of wire connection is selected.
The wiring in the chassis is confusing, which reduces the heat dissipation function and assembly of the whole machine, which has a great impact on the stability of the whole machine system.

IPC boot failure and solutions
1. After the IPC is turned on, the motherboard self-test is successful, but the system cannot be booted from the hard disk
1. Press the "Del" key to enter the CMOS hard disk parameter setting and boot order to see if the boot order is correct.
2. After booting with optical drive or floppy drive, check whether the hard disk of the industrial computer has a boot system or whether the hard disk is normal.

The difference between parallel port and serial port of industrial computer
Parallel interface, referred to as parallel port. The parallel port of the industrial computer uses a 25-pin D-connector. The so-called "parallel" means that 8-bit data is transmitted together through parallel lines, so that the data transmission speed is greatly improved, but the length of the parallel transmission line is limited, and due to the increase in length, the disturbance will increase.
