[0064] The core board is installed vertically on the switch board. The secondary switch on the switch board provides a stable network for each core board. The switch board also leads the system status and network status of each core board to the front end through signal lines, so that the working status of each core board can be directly seen in front of the chassis.

[0065] There are 8 switch board connection interfaces evenly distributed on the backplane. The switch board is connected to the backplane, and the switch board provides network and power supply services for the 8 core boards.

[0066] The backplane provides hot-swappable network board interfaces, switch board interfaces, and fan board interfaces. It can provide each switch backplane with no less than 1G network, provide 120W peak power supply for each switch backplane, connect the UART debugging function and USB line of the switch backplane with the control board, and provide 8 4-pin interfaces with a maximum power of 24W fan interfaces.

[0067] The high-performance switch chip 88E6393X on the network board provides network services internally. It provides two SFP+ module interfaces and one RJ45 interface externally, and uses the PCIE interface to connect to the backplane internally, and provides network services for the switch board on the backplane. When the bandwidth is insufficient, you can replace the switch with a larger bandwidth, making network changes simpler, more convenient and efficient.

[0068] The high-density ARM array server provided by the utility model has the following advantages:

[0069] By evenly arranging frame side panels between the frame bottom frame and the frame top panel to provide installation slots for the blade cage chip assembly, each set of blade cage chip assembly is fixed between the blade cage compartment assemblies through the mutual cooperation of the snap-in notch and the elastic fixing pin, and the core board is separately connected to the backboard through the exchange board, forming a modular assembly structure, which improves the user experience;

[0070] The fan cover is limited by the set network card frame, and the fan assembly is limited by the mutual cooperation between the elastic hook and the groove on the network card frame. The fan assembly can be removed from the system by releasing the mutual cooperation between the elastic hook and the groove. The installation and disassembly process is simple, which reduces the maintenance cost of the system.
