APP System Integration & Test Review (SITR) April 8, 2014 Agenda & Introductory Material
SITR SITR agenda: Status Response to assigned CDR RIDs Departures of delivered hardware and software from the design presented at CDR Post-CDR updates to this Integration and Test Plan and other critical documents Waivers, non-conformances, and changes to requirements Integration Plan Status: What was delivered (MEL)? Any discrepancies? ICD compliance Status of connectors and structures (cables, racks, cooling, grounding ) Test hardware Assembly procedures, including first application of power Disassembly, shipping and reassembly Anything else to be done prior to the PAI sequence Open issues and concerns Test Readiness Workshop (Tuesday p.m.) Work on reconciling procedures with full requirements matrix in I&T Plan

Departures from CDR design Delivered Hardware ROACH cards are configured on ALMA network, not on private network as proposed. Network switch and NIC were provided in case ALMA prefers to isolate them. Discrete 1 pps distributer implemented as final adder card (new Xilinx code). Maser rack design modified to incorporate a pair of standard seismic racks. Remote access added to maser.
Departures from CDR design Software (summary) Minor tactical changes only, including updated feature list
Post-CDR updates to documentation Updates to existing documents Integration & Test Plan V2.1 (changes) Hardware ICDs New Documents or summaries SITR plan Assembly procedures Summary of Engineering Change Requests (deviations from ICD or requirements) Problem and Failure summary report Non-conformance records
SITR Plan See document
Assembly procedures Maser power-up sequences (see maser I&T plan). This should be at a level of detail appropriate for high altitude operation. Pictures sent to support installation of PICs, power supplies, etc. Need to power down, insert cables, plug in, install boards. Test fixture procedures are same as have been followed during development. Some of this information will be captured in the maintenance plan. Some captured in PAI procedures. ESD protocols, etc.
Engineering Change Requests since CDR No requirements changes since revised I&T plan submitted Need to check on specifications such as set-up time between scans (slower than expected) B version of computing ICDs Between ALMA Phasing Project And ALMA Computing (ALMA-05.11.00.49-0004-B-ICD) Between C167 Microprocessor And ROACH2 FPGA (internal ICD, ALMA-05.11.10.49-0005-B- ICD)
Problem and failure reports (since CDR) Minor problem with DTS test fixture Solution: Operating system with 2 input channels instead of 3 Shorted pins in two connectors on the PIC. Solution: Move all of the signal vias so they fan-out on the outside edge of the pins instead of under the connector "Tent" all of the remaining vias under the connectors with solder mask to minimize the risk of shorts The assembler has taken steps to reduce the amount of solder used so it will also reduce the potential for bridging Cause: Workmanship 4 of 12 SFP+ cards failed incoming inspection. Solution: Failed boards replaced Cause: Unclear. 1 PPS maser signal failure after remote upgrade Solution: Reset on network card Mitigation: Document in maintenance plan Impact: Low (does not affect operation) Various software bugs fixed Unresolved issue in y-y polarization sum (firmware in LTA?). Note that x-x sum works fine.
Nonconformances and waivers No nonconformances No waivers

What was delivered? 2 recorders at OSF currently, one at NRAO. Two more will be shipped from Haystack to OSF when development is complete at Haystack, but may not be in time for PAS. OFL delivered to NRAO Maser to be shipped to OSF (est. May 10).
ICD Compliance See ICDs
Connectors and structures Cables, racks, cooling, grounding, etc. Cables Either in place or about to ship Maser? Check with Shep. Cooling: Unknown, need to measure PICA FGPA and PowerPC in AcRv sequence. Maintenance plan for Mark 6 should describe cooling issue with upgraded mother board. Measure OFL box at AOS? Maser should be ok, same as APEX. Battery life? Racks Maser rack structurally complete, requires grounding plan as part of maser PAI/PAS. Rails for recorders shipped
Test hardware Need to identify 2-antenna correlator (Bulletproof not available). Two in technical Facility Building (TFSD preferred, TFInt is option). Otherwise just routine lab equipment (scope, hand-tools).
Assembly procedures (Will walk through lab)
Disassembly, shipping, reassembly Piecemeal approach Component-level testing on install following ALMA protocols (regression testing) Maser shipped under battery power, needs to be delivered within TBD hours. See maser I&T plan. See Transportation Plan for crating. Revise transportation plan for maser. Shock sensors, etc., as needed.
