Clear-Com 4000 series 9RU chassis with
The Clear-Com Drake 4920 Series matrix comprises a 9U by 19 inch rack mount unit with all connections made from the rear of the frame. The Matrix power supply section comprises of plug- in PSUs, connected via two standard IEC connectors to the main supply. Access to the plug-in circuit cards is via the front of the frame, most cards having a corresponding rear connector unit fitted, accessed from the rear of the matrix.
Forced air cooling, with a 2U gap above the unit is required to maintain the unit at the correct operating temperatures. Drake recommends the use of a Fan Tray, such as the Drake PD3704. Inadequate or obstructed ventilation may result in serious damage to the system.
The 4000 Series II is a Digital Communications System using a central switching matrix for routing calls between outstations connected in a star format.
The digital central switching matrix uses a microprocessor for control and configuration purposes. A Digital Matrix Card, allowing multiple routes to be made simultaneously achieves all switching and routing. Analogue audio, GPI inputs and outputs, data interfaces and an advanced software package are also provided as part the 4000 Series II system
Each DAK may be centrally configured and assigned to a destination, source or both at system set-up. On some panels, DAKs that are not assigned at system set-up can be assigned, by local programming of the pushbuttons in Soft mode, to allow different routing options. Local assignments may not be retained if the system is reset, although they are held in non-volatile memory at the panel and thus will be retained after power down.
