Troubleshooting
A number of things can go wrong. If these solutions don't work for you, call an expert.
1. HV crate is on ? There are two power supplies which must be turned on.
2. The GUI connects to a Perl server on a PC. The PC/server then talks to the HV crate via a serial connection. If the server isn't working for some reason, rebooting the PC may help. The name of the PC is discovered in the tab corresponding to that crate; e.g. intelha3 on Left HRS.
