BW September 2018

9/6: Jim replaced the RBC55 UPS batteries for the APC SUA2200. There were four replacement batteries. He took out the old battery cartridges but had to keep the connections and covers for them to use on the new batteries. The new batteries just had to be screwed together and wired the same way the old ones were. Jim put packing tape around them to hold them together. There was a piece of foam that may have been between the old cartridges. Now it is between the new batteries.

9/7: I put a blue strap around newly cut light guides that look good enough to polish and use in normalization. The black strap is on ones that have flaws. I will decide next week which ones I should polish. There are a few extras that can wait, but one of the fibers is bent because I was pulling when it was wrapped around the axle in the spool storage box.

I should write a more extensive note next week about what happened with that spool storage box today.
