- A jumper fell off from the HVEast Layer 27, Sector 15. Check if it should power something.
Refer to <a href="png/ChannelMapEast-Down.png">East Down</a>, we know L27 S15 correspond to S4S1.12
Check the e-log page.
Find S4S1.12
L37 S18-20 powered by S4S1.12 / S4S0.1
Thus, L37 S18-20 should be powered by L27 S15.
Go down to check.
Ask Steve and Laura, check this E-log page, we found:
Layer 37/18-20 is now powered by Layer 28/13-15
So, L27S15 is no longer powered by L37 S18-20. It's OK for now.
Thanks for Steve and Laura.

We(Dan, Basit, Steve, and Xin) went down to the pit. Dan noticed that the connector has been damaged in the bus powering L37 S18-20. So, he plugged the power from L27S15 in by using the other spare connection in the bus.
Tomorrow, need to take a further look at the broken pin and try to cover it or replace it to make more safer.

Basit and I went down the pit. We unplugged the pin from the broken plastic plug and inserted it to another new plug and put them right below the original one. To make it firm, we also glued this one to the panel. After that, we put a red sticker around the plug indicating the message for safety reason.
Write to hardware e-log.
Took pictures.

Error message from the HV Server:
HVTripManager.cxx 376: Info (HV Control): ChannelKey HVPitEast L3, S1S1, Ch23 is not known to the Map
Look at the HVPitEast L3, S1S1, Ch23 in Inverse Map. It corresponds to
DR AnodeLayer,11,Sector,15 AnodeLayer,11,Sector,16
Open the HVDetectorMap file:
dat/HVDetectorMap_16_HVNormal.txt
319 DR AnodeLayer,11,Sector,15 HVPitEast 3 22 <-- 320 DR AnodeLayer,11,Sector,16 HVPitEast 3 22 <--
It turns out that in the latest Detector Map, the channel is 22 not 23.
