power cycled EX QPD interface and whitening
(Keita writing)
Nothing changed for green, it's hard to tell if anything happened for IR as there's no light right now.

Analog signal coming out of the interface looked OK in that no high frequency oscillation was observed in green as well as IR. Ditto for Analog signal coming out of whitening.

I didn't pull the QPD interface chassis out, as one of the clean room legs is blocking the front side of the ISC field rack and I couldn't move the clean room on my own.
