A temporary FSS chassis (S1812014) was installed on ISCT6. I connected the +/- 18VDC to the chassis as well and left it powered that way. The accompanying +/- HV power supplies were placed on the floor inside the squeezer rack and connected to the chassis. The HV supplies were set to 180VDC as per their counterparts in the CER mezzanine and then turned off until they're needed. WP#8029
We need a PFD not a DEMOD for the alternative locking scheme. The bottom unit is already a DEMOD. Will swap.
