The partition is equipped with test sockets 8 and power sockets 9, which can be quickly connected to the external interfaces on the KVM display 13, signal conditioning box 11, load switching box 12, and programmable power supply 16.
[0033] like Figures 1 to 6 As shown, in this embodiment, preferably, the bottom of the cabinet 10 is provided with casters 3, which makes the whole unit easy to move and transfer.

Integrated testing mode: based on the network mode, it grants control permissions to the host control device, receives relevant instructions from the host control device, and performs integrated testing; the purpose is the same as the network mode.
[0040] In the on-board testing, the testers used the PXI / CPCI controller 14 to simulate the electromechanical integrated management system and communicate with the chair-mounted central load unit 15 to complete the joint test. After the entire machine was powered on, a power-on self-test was performed, followed by periodic inspections of each electrical component.
