Dimensions and Cooling System

NOTE:
The size is 437mm inside of the device(without the cover plate and front panel).The size is

around 472mm of the complete device,but a little bit different size in the different front

panel.Some series with different size that had not shown, please learn it in the parameter.

Tunnel through cooling system
Cold air comes in from the front panel of the equipment, forms a duct through the radiator

to take the heat away and out from the rear panel of the equipment.
