The B84 EPP lab DAQ readout and PSU communications are supported by the rack at the 'ATLAS corner', network switch and lab supplied on the test bench. The nerve system for this infrastructure is the 1 GE ATLAS ITK network centered on a pair of linked network switches that offers copper ethernet sockets for DAQ readout components, scopes and crate hubs. A long fiber link also connects this network with the ATLAS rack in the B84 lower floor server room which hosts the RDDEV111 Linux server and ATLAS ATCA shelves. EPP lab also has a WiFi router connected to the ATLAS ITK network to allow half of the B84 ATLAS corridor offices closer to the EPP lab to reach this network by WiFi. Key ITk DAQ Network page has detailed description of the readout network with the RDDEV111 host server and X display/terminal with fastx3. Key equipment that require remote power controls can take regular 110V A/C power from ports served by the TripLite PDU in the rack.

The RDDEV111 server is the central hub that resides on both the SLAC public network and ATLAS ITK internal network, where various test DAQ and monitoring applications can be launched from. It also hosts disk space for test software and firmware and code build. Test data are also expected to be hosted here. Access to RDDEV111 can be via ssh from any node on the SLAC public network with your regular UNIX login for approved ATLAS users. Please send access requests to Matthias Wittgen. RDDEV111 also hosts a name server so that you don't have to remember the IP address of you favorite DAQ/monitoring equipment on the ATLAS ITk network but refer to them by node name, once logged on to RDDEV111. Your can also check the physical IP address an alias command for any name in case you need it (detailed instructions to come).

ISEG Control/Monitoring
Many PSUs and DCS monitoring components are from ISEG that are hosted in Wiener MPOD crates. An example control/monitoring of an ISEG HV module in the Wiener MPOC crate using SNMP in EPP lab from RDDEV111 through fastx3 on your laptop browser could look like this:
