End Station DC Power Supply Photographs
While at the end stations yesterday I took photos of the DC power supplies. I've included them here for future reference.
left-rack/right-rack is as viewed standing in front of the racks. Note that the end stations are mirror images of each other.

Note that the EY photos were taken with h1iscey not on SEI-YC1, so it was at 3A, now at 5A. Conversely h1iscey at this time was on ISC-YC1,TCS-YC1 so it was at 9A, now 6A.
