A big maintenance day today. While the DC power to the front end IO Chassis was being worked on, we shutdown all the CDS frontends with the exception of h1pemmx.

We then reconfigured the fibrer optics ports of the timing system. The MSR master, the two H1CER fanouts and the EY fanout were recofigured to the standard as agreed between LHO and LLO. The temporary fanout in the LVEA for the test stands and the MX fanout were not changed.

All the front end machines were powered down for this work. The MSR front ends were powered up in the order:

h1psl0

h1seib1,h16,h23

h1susauxh2

h1susb123,h2a,h2b,h34

h1lsc0,h1asc0, h1oaf0

EY front ends

LVEA Test Stand Front Ends

Some problem with h1pemey IO Chassis timing, moving the tcs SFP over to the pem IO Chassis fixed this.

All system should now be burt restored and switch on.
