Two quick questions.</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
1) How neatly do these need to be run, i.e. can I just use velcro/tape to secure cables or should it be properly cable wrapped/routed?</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
2) Has anything been decided on the damaged HV patch panel connector?</div>

it looks like there's debris in it as well. The quickest fix would be to just use the next connector down, but I don't know how easy that change is to make in software.

<span>I started to run cabling for the HTSB sensors in the detector but there is still some coolant lines that need to be insulated and/or connected so I didn't want to undo the HFCB disconnects that have been folded back. The insulation needs to be repaired
prior to connecting any of the detector cables since once the structure that holds the L1C is installed that part will be very difficult to access.</span></div>
