Looking at the RF distribution system for corner and end stations there are only 3 units which show an error:

• The RF divider for the 40MHz indicates a problem with the power supply. After swapping some cables this was traced to the RF Amp concentrator where channel 1 seems busted.
• The RF amplifier for TCS where the field cable is missing.
• The 90MHz LO for ASAIR_B which indicates no signal.

There is also an error associated with the green WFS demodulators where the hardware for the readbacks is still in the works.
