Hub SN-15 Trailer Sheet


04 NOV 2019
	- Begin work on SN15 per instructions found at /hardware/details/Hub_Inventory_Status_Final_Assembly/hub_msu_final_assembly.txt
	- Performed GND>COM/POS>COM/POS>POS resistance checks. All grounds and supplies
	conform to values given	in instructions.
	- Started with mechanical preliminaries - removing runners, cutting down corners
	to make room for ATCA handles, etc.
	- Did all part remove/replace/installs.

07 NOV 2019
	- Finished with initial procedure. 
	- Installed IPMC #202.
	- Handle switch and initial power-up tests worked first time through. Using four
          layers of clear packing tape, which has almost the exact same thickness as 
	  two layers of kapton.

	* Initial programming with safe config is questionable. It doesn't seem to be
	  holding programming from session to session. I.e., if I
		- Program the unit;
		- Disconnect Vivado and close out;
		- Throw the handle switch;
		- Power down the unit;
		- Disconnect JTAG;
		- Power the unit back on;
		- Restart Vivado;
		- Connect JTAG and re-open the device;
	  it shows up in the hardware manager as unprogrammed.
	* Waiting for Phillipe to come and either verify what I'm doing, or to point out 	  
	  what I'm doing wrong.

08 NOV 2019
	- Got unit programmed; Phillipe was kind enough to point out that 
	  I wasn't doing the flash step right.
	* When installing the heat sink, I grabbed the one out of the box that was Dan's
	  "practice" heat sink. It didn't have the channel cut into the side for the fiber
	  ribbons to fit in.
	- Had to R&R the heat sink. Correct one installed now.
	- Cleaned up "practice" part and will segregate it from the rest so that this 
	  doesn't happen again.
	- Unit is sitting in the storage cabinet waiting for its turn in 14SS.
12 DEC 2019
	- Unit was placed in the 14SS #2 and programmed using Pawel's scripts via
	  the instructions at /hub/testing/setup/ipbus_ibert/first_version

23 DEC 2020
	- Removed previously installed IPMC bypass from the handle switch. Installed 0 Ohm
	  jumper at ocation JMP5, direct enabling IPMC control of ISO_12V.
	  
14 APR 2020
	- Powered unit up on bench to update IPMC firmware.
