SUS-C7/ SUS-C8
Two HAM-A coil drivers were installed in the SUS-C7 rack, part of LO3. We decided to use the existing OMC cables for the new OFI. Cables are going to correct CER and field rack. OMC is being moved to the MER. Once HAM6 is vented the OM1/OM2/OM3 electronics and cabling will be removed.

SEI-C1
Started clean-up of the SEI racks. Removed a HAM ISI Interface Chassis from SEI-C1. This was part of the HAM1 L4C testing back in 2018. Plan is to remove the STS distribution electronics. See alog 89835 for testing of sending signals over IPC.

ISC-C3
The Heliax cable for SPI was landed in ISC-C3 (Patch Panel U37/U38, port 4) 

LVEA Work
Finished routing the ±18V power cable for CHETA Y around BSC8 and BSC1. Cable was landed in the TCS-R2 rack. We spent some time cleaning cabling in the TCS rack and the space between the TCSY enclosure and BSC1.
