• FEPS2 Power Supply Differences
a.) There is more room to remove the PCI cable from the Scan Control Board and pull it through 
the hole in the FEPS2.
b.) Two AC connections are still required but are mounted on front of the FEPS2 for easy access.
c.) The FEPS2 has two card ejectors so the screw in the bottom corner is not required to secure 
the supply.
d.) A special copper ground tab and ground plane grabber are incorporated in the FEPS2 to 
ensure good contact to the FEP card rack.
e.) A different FEP cover is needed, when an FEPS2 is installed, to add additional shielding 
around the Top Plane Board connecting the XDIF to the RF Amp.
f.) It is important that ALL screws be used when replacing the Front End Processor Cover.
• FEPS3 Differences
a.) FEPS3 Power Supplies must be used with TD5 and RF AMP2 Front End card racks. The +/- 
6V and 13V produced are required for these boards. Refer to Table 5-2 on page 5-6.
b.) Therefore, the FEPS3 can not be used with Front End card racks prior to R3.0.0 Software 
(BT’03).Figure 8-143   FEPS2 Grounding Points

8-134 Section 8-34 - Front End Processor Boards Replacement Procedure
• Installing the FEPS2/FEPS3
When installing the FEPS2/;FEPS3 in a LOGIQ™ 9 Front End Card Rack, special attention needs to 
be paid to the grounding points.
1.) Slide the FEPS2/FEPS3 in the card rack rails. See Figure 8-143 on page 8-133 .
- Ensure that the ground plane separating the SCB and FEPS2/;FEPS3 boards will slide into 
the ground plane grabber on the edge of the FEPS2/;FEPS3.
- Ensure that the copper grounding tab will make contact with the ground plane separating the 
SCB and FEPS2/;FEPS3 boards.
2.) Feed the PCI cable through the FEPS2/;FEPS3 and connect it to the SCB.
3.) Connect the two AC cables to the FEPS2/;FEPS3.
4.) Use the card ejectors to seat the boards pressing firmly on the top and bottom of the cards.
5.) Double check all ground plane contacts.
6.) When installing the FEP cover, ensure you use the new cover with the shielding riveted in the top 
plane area.
NOTE: Check the routing of the PCI cable through the Power Supply board. Ensure there are no loops 
in the PCI cable that could short to test points or any part of the Power Supply.
c.) The RF gasket on the inside of the Front End Processor cover MUST make good contact with 
the Front End Processor card cage. To get a tight fit with the gasket, loosely fit all screws 
through the cover into the card cage. Apply pressure to the bottom of the cover forcing it 
upward as you tighten all screws from the bottom up.

Section 8-35
Verify and Update Vital Product Data
8-35-1 Introduction
It is essential that Vital Product Data (VPD) is verified or updated after any hardware change to the Back 
End or Front End Processors.
NOTE: Failure to properly program Vital Product Data could cause adverse affects on system 
operation and image quality.
The items of concern are:
- Verify that the Board or BEP Vital Product Gata is programmed
- Program the new Board or BEP Vital Product data. (BEP VPD is stored on the FEP 
backplane).
8-35-2 Collecting Vital Product Data
For the Back End Processor, remove the system left side cover and read the label on the front of the 
processor. The Part Number is there. The Functional Revision is the PSP# (number) on the label. Get 
the date for the BEP from this BEP rating plate. All other dates are taken from the Console rating plate.
If the VPD Read Utility (8-35-3-3 Acquisition Diagnostics - Read EEPROM Data on page 8-138) shows 
no data for the Equalization Board (EQ), obtain that data by removing the system right side cover, 
remove the FEP cover, remove the EQ Board and obtain the data indicated in Table 8-9.

8-35-3-3Acquisition Diagnostics - Read EEPROM Data (cont’d)
Under this menu you will see a listing for each board that has an EEPROM with a location for Vital 
Product Data, see Figure 8-145 and Figure 8-146. The Board Data can be read individually or there is 
also a Read All Boards Utility.
2.) Click on the Backplane and Equalization items and select the Execute button to read the 
contents of the EEPROM on each circuit board. This will create two files for each board in the 
C:/Musashi/target/RW/Diagnostics directory. The files generated are a *.txt and *.dat file. The 
*.txt file will be the working file to edit where the *.dat file will be the file showing the actual 
hexadecimal data stored in the memory chip.
8-35-3-4 Modify VPD Text Files
Once data has been read back successfully and all files have been created, you are now ready to 
modify the contents of the *.txt file and write the data back.
1.) Open Windows Explorer via the CTRL-ALT-DEL method. Press CTRL-ALT-DEL 
simultaneously, select Task Manager, select New Task - Run, type in explorer in the Create 
New Task dialog box and select OK. If no Explorer window is open, click on the Explorer icon 
in the task bar to open a window.
2.) In Windows Explorer, navigate to C:/Musashi/target/RW/Diagnostics. Here you will see all the 
*.txt and *.dat files you have just created via the Read Utility. Each of the VPD files will have 
the prefix of “EEP-”.

Hints for Working with the Text Files
• Sort the files in the Explorer window, Figure 8-147, by clicking on the file TYPE
 heading. This will 
sort the files and put the .txt files in one contigious group.
• With the files sorted, to highlight all text files:
- Cursor to the first text file and press the Right-SET
 key.
- Cursor to the last file, hold down the SHIFT
 key and press the Right-SET key.
- All files should be highlighted.
- Ensure that the cursor is in the highlighted file area and press the Left-SET
 key.
- In the drop down menu, cursor to OPEN
 and press the Right-SET key.
- All text files will open up in Note PadFigure 8-147   Example of *.txt and *.dat File Listing

Notes For VPD Text File Editing
• There needs to be one (1) space between the colon (:) and the first character of the data string.
•NO spaces, characters, tabs, etc. at the end of the data string. Do a Fn-End (Function-End) on the 
LOGIQ
™ 9 keyboard to see the actual end of the line. Delete all spaces by back spacing to the text 
string.
• Double click on a word to select it for editing.
• Copy a field like the date for multiple pasting by: 
- Double clicking on the edited date field to select it.
-CTRL - C
 to copy the field.
- Double clicking on the next  field to edit.
-CTRL-V
 to paste in the copied text.
- You can do multiple CTRL-V
 operations for the text until you do another CTRL-C. 
• Use the board descriptions listed in Table 8-10 recorded prior to replacing a board.
• The Back End Processor data is edited in the Backplane text file.
• The file defaults values may have ?????? in a field, however this must be changed to alpha or 
alpha-numberic characters (whichever is valid for the field being updated). 
• Some boards may already have data present (no ??????). If this is the case, simply verify the data 
present with that recorded in the table and correct it if necessary.
• The EEP-PC VPD Data.txt file is for the PC2IP Board which is part of the Back End Processor FRU. 
This file does not need to be updated.
NOTE:Figure 8-148 on page 8-142  and Figure 8-150 on page 8-143  provide an example of a circuit 
board text file and backplane text file, with hints, for reference. Proceed to page 145 for further 
text processing.
