ALERT ! AV301 – NETWORK ERROR

Connectivity to the systems outside NMR lab is disrupted.  I will try to fix it remotely if feasible.  If not, one of us need to get to the system physically to reset the network. Access to the instrument over the weekend might be disrupted owing to this. NMR Facility Manager 4/21/2018
