Muon NGS Power Supply Firewall

The three NGS power supplies for the muon front end are controlled via TCPIP but hidden behind a dLink firewall box located in the cabinet to the left. Two of the supplies control SEPTUMA and SEPTUMC, with one (the one in the middle) the spare. All the power supplies are accessed internally on the same IP port (10001), but the firewall box port forwards so they appear externally under ports 10001,10002,10003 The firewall only allows access from MUONFE to the supplies. The firewall has a web interface for management.Login details for the firewall box are on the sharepoint access page

From top to bottom the supplies are

Supply Internal IP gateway external port SEPTUMA 192.168.10.10 192.168.10.1 10001 SPARE 192.168.10.11 192.168.10.1 10002 SEPTUMA 192.168.10.12 192.168.10.1 10003

Swapping a power supply

If the spare is used, you could eithr change its IP address to that of the replaced supply (no IOC changes required) or change the port number used by the IOC
