4. Procedure
Subtask 46-26-32-970-051-A ** ON A/C NOT FOR ALL

A. Uploading of the FOMAX Software with the Portable Data Loader (PDL)

NOTE: If the PDL has the digital signature check, it can send two messages:

One message if the PDL detects that the software has no signature. You can ignore this message, it has no effect on the aircraft software uploading.
One message if the PDL detects an incorrect signature. If this occurs, the software uploading is not possible and you must use a different software.
Because of data security, Airbus recommends that you send a report of the fault to the Aircraft Security Focal-Point.

ACTION	RESULT
1.Make sure that you have all the necessary media disks to do the uploading.
2.On center pedestal 11VU, on the Data Loading Selector Unit (DLSU): Set the ON/OFF switch to ON.	On the display of the DLSU, the indication that follows comes into view: DB/N:XXXXXXXXXX DLSU. Default value: '----------'. NOTE: The XXXXXXXXXX indication is the Part Number (PN) of the database software installed in the DLSU. Default value:'----------'.
3.On center pedestal 11VU, on the DLSU: Push the NEXT key.	The DLSU does self-tests.
4.Make sure that no error message comes into view.	On the display of the DLSU, the indication that follows comes into view: STANDBY PUSH PREV/NEXT.
5.On center pedestal 11VU, on the DLSU: Push the PREV or NEXT key until you get the FOMAX(64TA) indication.	On the display of the DLSU, the indication that follows comes into view: FOMAX(64TA) NOT SELECTED.
6.On center pedestal 11VU, on the DLSU: Push the SEL key.	On the display of the DLSU, the indication that follows comes into view: FOMAX(64TA) SELECTED. NOTE: If no PDL is connected, the indication that follows comes into view: CONNECT PDL PUSH SEL.
7.On the PDL: Start the uploading of all the software components that follow in this sequence and one after the other (for more information, refer to the PDL user guide): FOMAX CORE software (64TASW1) FOMAX CONFIGURATION DATA software (64TASW2) A/L FOMAX CUSTOMIZATION DATA software (64TASW3) AIRBUS FOMAX CUSTOMIZATION DATA software (64TASW4). NOTE: You can upload these last three software components independently if the FOMAX CORE software is uploaded. NOTE: The FOMAX can operate only when all the four software components are uploaded. NOTE: After each software installation, the FOMAX reboots automatically. NOTE: The uploading of the FOMAX CORE software erases the three software components related to the FOMAX CONFIGURATION DATA and the FOMAX CUSTOMIZATION DATA. If this occurs, it is necessary to upload the FOMAX CONFIGURATION DATA software (64TASW2), the A/L FOMAX CUSTOMIZATION DATA software (64TASW3) and the AIRBUS FOMAX CUSTOMIZATION DATA software (64TASW4) again.
8.When the uploading is completed, on center pedestal 11VU, on the DLSU: Push the SEL key.	On the display of the DLSU, the indication that follows comes into view: FOMAX(64TA) NOT SELECTED.

B. Check of Correct Data Transfer
(1) On the PDL, do the initialization procedure (for more information, refer to the PDL user guide).
(2) On the PDL, the Functional Item Numbers (FIN) and the PNs of the FOMAX hardware and FOMAX software come into view.
(3) Make sure that the PNs shown on the PDL are the same as the PNs that you recorded.
(4) On center pedestal 11VU, on the DLSU, set the ON/OFF switch to OFF.

B. Check for the Correct Data Transfer
(1) In the cockpit, start the Multipurpose Control and Display Unit (MCDU) 1 or 2.

NOTE: The procedure that follows is applicable to MCDU 1 or MCDU 2. The actions and the results of this procedure occur on the MCDU that you use.

(2) Adjust the brightness of the MCDU screen.
(3) Do a check of the PNs loaded in the FOMAX:

ACTION	RESULT
1.On the MCDU: Push the MCDU MENU button.	On the MCDU: The MCDU MENU page comes into view.
2.On the MCDU: Push the line key adjacent to the CFDS indication.	On the MCDU: The CFDS page comes into view.
3.On the MCDU: Push the line key adjacent to the AVIONICS CONFIG REPORT indication.	On the MCDU: The AVIONICS CONFIG REPORT page comes into view.
4.On the MCDU: Push keys 4 and 6.	On the MCDU: At the bottom of the MCDU, in the scratchpad section, 46 comes into view.
5.On the MCDU: Push the line key adjacent to the START indication.	On the MCDU, on the AVIONICS CONFIG REPORT page, the indication that follows comes into view: IN PROGRESS.
Wait until the Centralized Fault Display Interface Unit (CFDIU) calculates the Avionics Communication Router (ACR) for the FOMAX.	On the MCDU, on the AVIONICS CONFIG REPORT page, the indications that follow come into view: ATA and the EQUIPMENT /LRU indications come into view.
6.On the MCDU, on the AVIONICS CONFIG REPORT page: Push the line key adjacent to the 462632 indication.	On the MCDU, on the AVIONICS CONFIG REPORT page, the indications that follow come into view: EQUIPMENT /LRU FOMAX FOMAX OP software FOMAX CONF DATA software FOMAX AIRBUS DATA base software FOMAX A/L DATA base software.
7.On the MCDU, on the AVIONICS CONFIG REPORT page: Make sure that all the P/Ns of the 462632 / FOMAX are the same as the P/Ns that you recorded.
8.On center pedestal 11VU, on the DLSU: Set the ON/OFF switch to OFF.

(4) Decrease the brightness of the MCDU and stop MCDU 1 or MCDU 2.
