Dear All, 
Today Souvik and I went to refill the coolant, reservoir level went from 74% to ~88%. The leak rate now is 0.48 lit/day. Overall no issues, things are running smoothly.

We also went in with Wayne to do an inspection for installing a network switch. With the help of Tim we now have procured three 208V power supplies which are switched on and off by the presence of 120V input. Wayne has configured a 120V Network Power Switch as fst-nps1.starp.bnl.gov which can be used to switch those supplies. Basically, we've all the components in place. Also, we have to decide how we access the switch do we enable a SNMP communication established or a GUI – these switches will be we under expert control only. 

We also did a survey of the locations where we can mount them. As per the decisions made in FST group meeting we will do the network switch after end of run 2024. 

Best, 
Prithwish
