Subject: Fibers pulled, new FB install tomorrow 

[Aidan, Tara, Joe]

We pulled out what used to be the LSC/ASC fiber from the 1Y3 arm rack, and then redirected it to the 1X1 rack.  This will be used as the c1ioo 1PPS timing signal.  So c1ioo is using the old c1iovme fiber for RFM communications back to the bypass switch, and the old LSC fiber for 1PPS.

The c1sus machine will be using the former sosvme fiber for communications to the RFM bypass switch.  It already had a 1 PPS timing fiber.

The c1iscex machine had a new timing fiber already put in, and will be using the c1iscey vme crate's RFM for communication.

We still need to pull up the extra blue fiber which was used to connect c1iscex directly to c1sus, and reuse it as the 1PPS signal to the new front end on the Y arm. 

Alex has said he'll come in tomorrow morning to install the new FB code.
