I can easily enough just put a new back-shell onto it. The bigger problem is what all the rest of the wiring in that rack looks like. It's shameful frankly...
That looks worse than under/behind my desk. And I am not touching anything unless I need to do so.
Meh, that pales in comparison to the Brocades we installed for NASA.
We had a bunch of these fully populated with 10G cards and the requirement was some ridiculous 1 packet per day of loss, all multicast traffic. We had to do a lot of work with Brocade to make it meet the requirement.

10G? The chassis I'm sitting on will take 288 100G interfaces and has 75Tbps of switch bandwidth. We make one double that size too, but it's too tall to use as a stool.
Troll has a system called NavTrack which does basically that job, but better. We have it on our helicopter. A GPS receiver at the transmitter figures out where it is, then encodes this information onto one of the audio channels. At the receiver, it decodes this and, knowing where it is (if the receiver is moving, you'd best run away from the tower quickly), points the dish in the correct direction in both azumith and elevation.
Our system couldn't send to the tower. I can't remember exactly why, but I think it had something to do with the radios they were using for that at the time. The spectrum was probably in a bad range. I don't think they had in-band back then, either. Also, it was a different use case since they weren't going to keep the thing running while on the move. Just park and setup. It's much easier on an aircraft that's not bouncing around through a desert. The rack in the vehicle exceeded all our estimates for shock and vibe. The suspension wasn't rated correctly for the weight of the container.

Can't really tell what it is from the pic. Doesn't look like 100G interfaces.
Steven Hawking was smarter than all of us here combined. Respect to a brilliant man who who could understand and work with concepts most of us will never be able to grasp fully. I have at least one of his books and read a number by others where he played a very important role in understanding how universe works. He was told that he wouldn't live past 25 years of age and even though he became wheelchair bound, unable to do most things humans take for granted - he continued working on advancing our understanding of this world. Laugh all you want, but it is a sad day for humanity. We were lucky to live with the equal of Einstein.
His wish for the tombstone was to have "Hawking’s equation" written on it - a formula for black hole entropy.
Understanding that there is a problem with quantum particle-antiparticle pair at the edge of the event horizon, which leads to black hole information paradox was more than anyone else was able to do on the subject. He first formulated the concept of information (radiation) escaping black hole and shortly before his death proposed a solution to this problem. His formulas are not super complex, other scientists understand them and can apply appropriately. There is nothing to say that they can never be tested. Just like humans are able to find planets outside of our own galaxy or tell the predominant composition of planets on the edges of our galaxy without ever seeing them with our eyes, taking a soil sample or using ground penetrating radar, we may be able to verify the solution without having a black hole in a test lab.

We've been moving away from the "one big central switch" concept towards a more distributed approach. This is the hardware for the current phase of the project:
A few of them installed and running in a different room. This pile replaces an old Catalyst 6500.
