Hardware system function

Remote maintenance function: can query the running status of all board cards and other information through remote;

Board card maintenance function: the equipment has external DC or AC power input (Note: 1U only has double 48V power supply), double power and double thermal backup;The power supply design has fuse overcurrent, which can be replaced;The board adopts modular design, and all the board cards can be replaced by electricity, easy installation and maintenance.

Equipment alarm function: the equipment has the function of sound and light alarm. When the equipment fails, the ALM light will be red and the buzzer will send out an alarm sound.

Single configuration function

The 1U offers four (0.5U height) service slots, a dual 48V power slot, a master control slot and a fan slot
