Insert the board afterwards. BACKGROUND OF THE INVENTION With the development of telecommunication services, telecom operators are paying more and more attention to the flexibility, openness, scalability, and stability of telecommunication platforms. Therefore, PICMG (PCI Industrial Computer Manufacturers Group, PCI Industrial Computer Manufacturing Organization) proposed the specification of ATCA's open hardware platform, called PICMG 3.X specification, which relates to ATCA's mechanical architecture, power supply system, heat sink, and switching. Structure and interconnection, system management, backplane structure, etc. are described in detail. According to the PICMG 3.X specification, in the ATCA-based system, each chassis is equipped with two CMMs (Chassis Management Modules), which are independent boards and are directly inserted on the ATCA backplane. As shown in Figure 1, each CMM can manage all the boards or FRUs (Field Replaceable Units) in the chassis. IPMC (Intelligent Platform Management) is required in each board. The function of the controller, the intelligent platform management controller, the IPMC mainly monitors, controls, and manages various critical hardware resources on the ATCA board or other chassis components, including the status of the effective payload part of the board or module, and the board. Temperature and voltage detection, hot swap management, FRU information acquisition, alarm management, power management, reset status, sensor and event management, log management, E-Keying (electronic switch) management, etc., while completing the AMC (Advanced Mezzanine Card) , advanced mezzanine daughter card) management and event record of daughter card hardware address, temperature, voltage, reset, hot swap and alarm indicator , Through the dual redundant IPMB (Intelligent Platform Management Bus, Intelligent Platform Management Bus) bus communication with the CMM, and the events are reported to the information for management and control of CMM and CMM.

The PICMG 3.X specification also states that the HUB BOARD of the ATCA chassis system provides dual redundant three pairs of differential clocks to the NODE BOARDs in the ZO E2 area of the backplane. To meet stringent system synchronization needs. As the field of ATCA system application becomes more and more extensive, the switching capability, service processing capability, and media access capability of the ATCA system need to be improved. In the ATCA chassis of the PICMG 3.X, as shown in Figure 2, the 14-slot ATCA chassis, the 7 and 8 slots are configured as the switching board (HUB BOARD), and the remaining 12 slots are nodes. Board (NODE BOARD); Exchange board BASE Interface (basic interface) can only provide 15 The channel interface, the fabric interface (switch interface) can only provide 15 channels at the maximum, and the service processing capability of the system is limited because the switch board occupies the slot of the two-node board. In addition, in the system, the rear card is inserted in the same manner as the front-plug card, and the expansion of the front-panel interface is mainly implemented, so that the media access capability is insufficient. Therefore, the PICMG 3.X specification of the ATCA chassis system architecture needs to be improved. The most important thing is to keep the front-plug server blade in compliance with the PICMG 3.X specification, directly connect the rear-mounted board to the backplane, and expand the post-insertion board.
