5:00PM System status summary

Detector fully hooked up.
FEB chiller at +20C.
SVT chiller at +20C.   
FEB power looks good on all boards.

Summary:

Two FEBs have issues. Including notes on those below.

Physical FEB: L4b Serial: 8 FebFpga: 8 Fiber: F
==============================================
DataDPM 0, DP 0, Hybrid 3, all sync 
DataDPM 0, DP 1, Hybrid 2, all sync 
DataDPM 0, DP 2, Hybrid 1, all sync
DataDPM 1, DP 0, Hybrid 0, 4/5 synced

All of these synced initially, but after trying to resync, they began to have issues. The APV's on Hybrid 0 seem to drop in and out of sync. After power cycling, the issues persist with Hybrid 0. The peak and base values on APV 4 look off. After playing with the AdcClkPhaseShift and Data delays and setting them back to what they initially were, the sync and base values on APV 4 improved. We will know if there is an issue with the data after a run is taken. 

Physical FEB: L6b Serial: 13 FebFpga: 6 Fiber: F 
==============================================
Control link has several errors which don't allow communication to the board. Switched control fibers E and C at the COB. The FPGA number switched to 3. There were no data links present. Looking at the oscillator that is used to driver the links, the frequency is at half of what is it suppose to be.

Detailed log on each FEB below:  

Physical FEB: L1t Serial: 9  FebFpga: 2 Fiber: A
==============================================
DataDPM 0, DP 0 (No hybrid connected)
DataDPM 0, DP 1 (No hybrid connected)
DataDPM 0, DP 2, Hybrid 1, all sync
DataDPM 1, DP 0, Hybrid 0, all sync

...

All of these synced initially, but after trying to resync, they began to have
issues. The APV's on Hybrid 0 seem to drop in and out of sync. 

After power cycling, the issues persist with Hybrid 0.

The peak and base values on APV 4 look off. After playing with the
AdcClkPhaseShift and Data delays and setting them back to what
they initially were, the sync and base values on APV 4 improved. We will
know if there is an issue with the data after a run is taken.
