While the PSL was down this morning, we took the opportunity to reboot Corner 4 and Corner 6 EtherCAT chassis.  This was to determine if a reboot would fix bad readbacks described in this ALOG 40152  In the case of the H1 SQZ 42.375 MHz the reboot was successful in restoring the signal.  In the case of ASC-AS_B_RF42_DEMOD_LOMONCHANEL_3/4 it did not work, the offset is still present.  The plan now is to swap the beckhoff terminal in Corner 4 when a clear opportunity arises.  Until then I will leave WP 7309 open.
