DMK520 Rack Console monitor keyboard enables you to control your server using a single keyboard, monitor, and mouse. Its dual-rail design represents an intelligent use of rack space. Essentially, two sets of slide rails are attached to the LCD and keyboard allowing each component to slide in and out of the rack independent of the other.
The operator can hide the keyboard while still allow the LCD to remain displayed, even if the rack door is closed. And it gives an additional level of server management security by having the keyboard hidden to prevent unauthorized access.
