Hub Module - MSU Final Assembly --------------------------------- Initial Rev. 26-Apr-2017 Current Rev. 16-Oct-2018 This document describes both the Electrical and Mechanical MSU Final Assembly of the Hub Modules. First Part of the mostly Electrical Final Assembly: --------------------------------------------------- - Start the Trailer Sheet for this Hub and record the start work date. - Verify that the ESD Grounds, e.g. strips along the bottom of the card, RJ-45 shields, and guide pin receptacles are all connected. - Check the resistance from the various power buses to Ground looking for shorts - all OK with similar values shown below: DCDC-1 FPGA_Core about 4 Ohm DCDC-2 MGT_AVCC " 30 Ohm DCDC-3 MGT_AVTT " 180 Ohm DCDC-4 MGT_AVAUX > 1k Ohm DCDC-5 Switch_1V2 about 450 Ohm DCDC-6 BULK_1V8 " 300 Ohm DCDC-7 FAN_1V8 > 1k Ohm DCDC-8 BULK_3V3 > 1k Ohm DCDC-9 BULK_2V5 > 1k Ohm CLK_BULK_2V5 > 1k Ohm CNST_5V0 > 1k Ohm Check Both Ends IPMC_3V3 > 1k Ohm IPMC End IPMC_3V3 about 125 Ohm Power Module End ISO_12V > 1k Ohm Hold_UP + and - > 1k Ohm Check Both Ends Check also for power bus to power bus short circuits. - Write Serial Number SN-?? on the card. - Temporarily install the two front panel delrin mounting brackets to help support the front edge of the Hub pcb when it is up side down. Use 4-40 x 1/2" button head screws. Note that flat washers can not be used under these screws because with flat washers the head of the screw does not fit under the lip of the front panel. - Cut and File smooth the top and bottom edges where the assembly rails have been removed from the Hub pcb. - Cut down the thickness of the pcb for the front panel Handles. Cut from the back side. Cut in a circle about 0.40" diameter and running tangent to the edges of the card. Cut down through 2 Ground Planes - just barely cutting through the second Ground Plane. Using the micrometer verify that the whole cut down area is flat. The remaining pcb thickness sould be about 105 to 107 mils. File the edges smooth. Explore with an exacto knife to verify that there are no loose strands of copper trapped in the edges of the cut out area. Clean up in copper burs in the bore of the lower front panel mounting hole (the upper hole has a G10 bore). Air hose all cut G10 and Copper off from the card. Super glue the rough edge of the cut out area to seel the rough edge and improve the look of this part of the card. There are now almost two full layers of G10 between the metal of the ATCA handle and the next Ground Plane in the card. There are no traces in danger in this part of the card. There are two Ground Planes between the metal part of the ATCA Handle and the first possible "hot" parts of the card. - Clean off flux residue around J2 and around ATCA Power Modules. While cleaning J2 verify that all of its solder connections have been done corectly. - Install the Guide Pin Receptacles with M2.5 10mm and flat washer. - Re-press in the Zone 1 & 2 connetors and the RJ45s. - Install 2 of the 4 backplane MPO connectors with 2-15 5/16" screws and lock washers. For now I'm installing the top and bottom MPO connectors. - This step is only necessary on the 8 prototype Hub Module. These 4 ICs should be installed at the Assembly House on the 20 production Hub Modules. Install the 4 TSSOP parts on the back side; 3x 24 pin 1x 14 pins. U551, U553, U554 are 74AVCH8T245s U552 is 74LVC07A Do a full clean up of the area around these 4 IC installations including on the top side. - Remove the following components from the Power Supply sections: R1001 DCDC_1 Assembly House value was 180 Ohm R1201 DCDC_5 Assembly House value was 180 Ohm R1251 DCDC_6 Assembly House value was 180 Ohm Remove the following resistor "straps" "jumpers" from the Phys Chips circuits U21 and U22 to set them up in the new standard way for Hub Module operation, i.e. Physical Address = 000 Phys Chip Mode = 1100.

Note that these have Kapton tape under them to make certain that the PLL PCB does not contact any of the vias in the Hub PCB and visa-versa. - Install the post L RC network on the filtered MGT supplies. MGT_AVCC 2x 820 uFd 2.5V 7 mOhm Al-Poly plus 25 mOhm MGT_AVTT 1500 uFd 6.3V 7 mOhm Al-Poly plus 25 mOhm FAN_1V8 1500 uFd 6.3V 7 mOhm Al-Poly plus 25 mOhm Use heat shrink tubing and teflon tubing to insulate the leads on these RC networks. Use keystone solder lugs to ground the MGT_AVCC and MGT_AVTT networks to heat sink mounting screw holes (which are grounded). Use teflon tape to insulate the cases of the MGT_AVCC capacitors from the FPGA heat sink and from the Hub pcb itself. Be especially careful of the small vias in the pcb that are under the lead end of these MGT_AVCC capacitors. - Install the discrete power wires. So far it appears that I do not need to connect the big hold-up capacitors in the NE corner for the ATCA Power Entry module to work. So currently there are 6 discrete power wires that need to be installed: 3x Iso_12V, IPMC_3V3, CNST_5V0, Clk_2V5. So far I have just tied and not glued down the discrete power wires. Install the discrete power wires in the order: Bulk_2V5 at the regulator end Bulk_2V5 at the clock generator end IPMC_3V3 at the power supply end CNST_5V0 at the power supply end Shortest ISO_12V at the power supply - east most via Middle ISO_12V at the power supply - middle via Longest ISO_12V at the power supply - west most via Shortest ISO_12V at the load Middle ISO_12V at the load Longest ISO_12V at the load IPMC_3V3 at the load CNST_5V0 at the load More Mechanical Final Assembly steps: ---------------------------------------- - Install the LED Light Guides 6 Single LED Light Pipes (1x 1, 1x 2, 1x 3) 6 Quad LED Light Pipes - Cut the height of the active edge of the mid bracket down by 0.190" as it no longer loops in back of the card but rather uses 7x of the high density tape. Cut a notch that is 0.160" wide by 0.060" deep (i.e. almost up to the screw holes) in the active edge of the mid bracket. This notch is for the IPMC_3V3 and CNST_5V0 power wires. In a new version of the front panel and this bracket I need to move the location of the two 4-40 screw holes to the right by 100 or 200 mils. - Machine as required the diameter of the front panel handle mounting boss. - Add as required any additional holes or cut-outs to the front panel, e.g. along the back side lip. - Add 7 layers of the UHD tape to the backside of the pcb directly under where the front panle center mounting bracket is located. - Install the Front Panel If you install the heatsink last then it is easy to work with the card (i.e. without the FPGA heat sink there is no problem of setting the card on its FPGA heatsink). Once both the front panel and FPGA heat sink are on the card it is hard / impossible to see in to verify that the MGT_AVCC capacitors are OK. Remember that the FPGA heatsink needs kapton tape on the edge of the fill block and on the bottom surface of the heatsink in the area of the MGT_AVCC capacitors. More Electrical Final Assembly: ------------------------------- - On the 20 production Hub Modules: Install the ATCA Handle Switch by first soldering AWG #26 connection wires to the bare switch: Red wire to the Common terminal Black wire to Open terminal when card is inserted & latched Yellow (if used) to Connected term when inserted & latched Protect these wires with heatshrinking on the switch terminals. Red wire to WTerm_72 i.e. R961 100 Ohm to IPMC_3V3 Black wire to WTerm_71 i.e. RC1559 and IPMC pin 224 Yellow (if used) to JMP5 JMP6 common end with both jumpers removed. This is only for direct Handle Switch control of power on the Hub Module. Only on the 8 prototype Hub Modules: Install the On-Off Switch if it is being used on this Hub card. In any case temporarily install an On-Off Switch so that the card can be powered up on the bench. If the Lemo is not installed the the Lemo front panel hole may be used for a temporary On/Off switch. - Install the Insulated Lemo Connector if it is being used on this Hub card. Initial Power Up Checks: ------------------------ - Check of the Hub SN-?? voltages and currents during initial running. Configure the Hub FPGA with the Safe/Foundation firmware for this test. Setup the 7x DCDC converter power supplies as described below.

Once the range of the PLLs has been checked then install the "Spare Oscillator" and its output pull-down resistors. Record the frequency of the Spare Oscillator (shown above). - Program the Flash Config Memory with the Safe/Foundation firmware. - Verify that this Hub Auto-Configures at power up. - Verify that the 4 front panel Ethernet jacks work. Setup the DCDC Converters on the Hub Module: -------------------------------------------- There are 7 DCDC Converters on the Hub Module that can be monitored and controlled via the I2C PMBus. Control of these converters includes setting values in their non-volatile memory that they will use the next time that they power up. Values that we need to set in their non-volatile memory include: Vout_Scale_Loop # see below Vin_On # set to 6.50 Volts Vin_Off # set to 5.50 Volts Vout_Trim # set only after power supply study Vout_Margin_Hi # set to 1.03 x Vout Nominal Vout_Margin_Low # set to 0.97 x Vout Nominal We must set the Vout_Scale_Loop parameter for many of the other control parameters to operate correctly. Recall the values of Rtrim = R2 and Vout_Scale_Loop for the various output voltages used in the Hub Module power supplies: Power Supply Rtrim Output Voltage = R2 Vout_Scale_Loop -------------- ---------- --------------- 0.950 V 34.3k Ohm 0.6316 1.000 30.0k 0.600 1.200 20.0k 0.500 1.800 10.0k 0.3333 3.300 4.444k 0.1818 Recall how to calculate the Vout_Scale_Loop parameter Vfb Vout_Scale_Loop = -------- where Vfb = 600 mV Vout nom Rtrim or Vout_Scale_Loop = ----------- 20k + Rtrim In the TI documentation Rtrim is called R2 i.e. the resistor from the feedback pin to ground. R1 is the resistor from the output voltage to the feedback pin and is 20k Ohm in all of the converter modules used in the Hub. The Margin voltage set points that will be used in the Hub Module power supplies are all set for +- 3%. Their values are: Power Supply Vout_ Vout_ Output Voltage Margin_Hi Margin_Low -------------- --------- ---------- 0.950 V 0.979 V 0.922 V 1.000 1.030 0.970 1.200 1.236 1.164 1.800 1.854 1.746 3.300 3.399 3.201 Start up of the Digital Power Insight GUI program DPI_GUI on the tough-book: > cd C:\DPI Suite\DPI Suite\DPI_GUI > dpi_gui 6 This is how you get the 6 "POL" windows. Running the DPI GUI with 6 POL windows what you can monitor and control is: Setup of the 7 DCDC Converter (see only the first 6 with DPI_GUI) Not Seen Address: 40 41 42 43 44 45 46 0x28 0x29 0x2a 0x2b 0x2c 0x2d 0x2e DCDC: 1 2 3 5 6 7 8 Vset Res kOhm: 34 30 20 20 10 10 4.42 Power Bus: FPGA MGT MGT Swch Bulk Fan Bulk Core AVCC AVTT 1V2 1V8 1V8 3V3 Vout-Scale_Loop: 0.632 0.600 0.500 0.500 0.333 0.333 0.182 From the DPI_GUI (which can only see and work with the first 6 POL converters) we set in their non-volatile memory new values for: Vin Turn_On & Turn_Off, for Margin Hi & Low, and for the Vout_Scale_Loop parameter. The Vout_Scale_Loop parameter is (can be) set because in the upper part of the DPI_gui display we must fill in the value of the Rtrim resistor for each converter. - When the DPI_GUI starts up use the "find modules" button in the very bottom right-hand corner. You sould now see DCDC Converters number 40 through 45 by their decimal I2C address. - Set the value of the Vtrim resistor in k Ohms for each converter (in the next to top line of the display) and you should then see the correct default Vout voltage. - Edit the lower section of the main DPI_GUI window for new values of Vin Turn_On and Vin Turn_Off. This is the Settings section of the main window. - I'm using a Vin_ON of 6.5 Volts and a Vin_Off of 5.5 Volts. - Edit the lower section of the main DPI_GUI window for new values of Vout_Margin_Hi and Vout_Margin_Low. This is the Settings section of the main window. Use the Margin values that are shown in the table above. - Make certain the the Polling is turned off and that none of the POL modules are seleced for Status Polling. If the polling is running the its I/O seems to make errors in the write settings and Store Defaults I/O. - Select the column, i.e. the POL converter that you want to update by setting it select radio button at the very bottom of its column. - If necessary do a Clear Faults. - Do a Get Status to verify that there are no problems. - Do a Write Settings to put the new/edited settings from this GUI display into the Working Memory of this converter. - Do a Store Defaults to write the new/edited settings from the Working Memory of this converter into its non-volatile memory. - Do a Get Status to verify that there have been no I/O errors with this converter will the new/edited settings were being written to it. - The Store Defaults should just be storing into the controller's eeprom of each converter new values for: Vout_Scale_Loop, Vout_Margin Hi/Low, and Vin On/Off even thouch it's rewriting all of the values in the eeprom. Loop over all 6 of the converters that you need to update using the DPI_gui. Note that in the above scheme that you are writing new values into both the converter's Working Memory and into its non-volatile eeprom memory. For the 7th DCDC Converter, Bulk_3V3, you need to use the DPI_CLI program to reach it. To start the DPI_CLI program on the tough-book: > cd C:\DPI Suite\DPI Suite\DPI_CLI > dpi_cli When DPI_CLI starts up you need to enter "46" to select the Bulk_3V3 converter. You can read things e.g. > read vout > read iout > read vin > read vin_on > read vin_off > read vout_scale_loop > read vout_margin_high > read vout_margin_low Look at the "DATA" line to see the returned value in engineering units. You then write new values to the convertrs Working Memory: > write vout_scale_loop 0.182 > write vin_on 6.5 > write vin_off 5.5 > write vout_margin_high 3.399 > write vout_margin_low 3.202 To save all working registers to the non-volital eeprom you can use: > write 11 Command 13 for saving just a specified register to the eeprom does not seem to work as it just causes the dpi_cli program to crash. Install the FPGA Heat Sink: --------------------------- - Install the FPGA Heat Sink Finish any final machining on the FPGA heat sink before installing it, e.g. cut-outs for either the MGT_AVCC or MGT_AVTT capacitors, center air hose barb, inlarge the 4 mounting screw holes from #33 to 0.125" diameter. Mill flat the two surfaces of the filler block. Sand the two surfaces flat with 120 and 180 grit paper. Clean and Assembly the filler block and heat sink. Use Kapton tape in the area of the MGT_AVCC capacitors. Use the good end of the compression springs against the 4x tightening nuts. Tighten just far enough so that all threads in the nut are in use.
