-
2 DUs housed in racks on the Captain's main instrument panel
-
2 DUs housed in racks on the First Officer's main instrument panel
-
2 DUs housed in racks on the center instrument panel
-3 DMCs (Display Management Computers) common to the EFIS and ECAM systems, located in the avionics compartment
-2 SDACs (System Data Acquisition Concentrators) located in the avionics compartment
-
1 dual EFIS/FCU, located on the glareshield, and called the FCU (Flight Control Unit), including CAPT and F/O EFIS control sections
-
1 ECAM control panel, located on the center pedestal
-One set of transfer selector switches accessible to the Captain and the First Officer located on the center pedestal. They provide EIS reconfiguration controls in case of DMC or ECAM DU failure
-Control/brightness potentiometers for the DUs: those concerning the EFIS DUs are located on the left side of the CAPT and on the right side of the F/O instrument panel (301VU and 500VU) those concerning the ECAM DUs are located on the ECAM control panel
-One PFD/ND transfer pushbutton switch for each pilot, located between the PFD and ND control/brightness potentiometers.
-Two sets of visual attention lights, located on the glareshield, on either side of the FCU, each including a MASTER WARN light and a MASTER CAUT light; these lights are of the pushbutton switch type
-Maintenance and test controls accessible through the MCDUs
-Circuit breakers: those connected to ESSENTIAL bus bars are located on the panel 49VU of the overhead panel, the others are located on the panel 120VU.
3. Power Supply
____________ The 3 DMCs, and the 6 DUs are supplied with 115VAC/400 Hz single phase. The FCU and ECAM control panel are supplied with 28VDC. The table below gives the main electrical power sources for each component.
NOTE : The DMCs and DUs are also supplied with 28VDC for switching purpose

(Ref. Fig. 008)
In emergency configuration, the static inverter then the AC and DC power supplies are restored for some components, by means of the hydraulically driven emergency generator. The hydraulic power source is the ram air turbine (RAT).
As far as the EIS components are concerned, power supply is given to:
-DMC1 (or DMC3 if selected by CAPTAIN)
-ND1
