Tests for Dec 2012

Objective

• System to conduct pulsar observations
• Complete system test
  • ROACH-II
  • HPC low and high bandwidths
  • Writing into networked disks
  • Using switching signals
  • Modes 1 and 13, at least.
  • Control with GBT M&C system

To-do list to accomplish these objectives

Hardware (Assigned to Jason with Galen responsible for the IF items)

• Stuff for Berkeley to borrow or buy:
  • 5 SFP+ NIC cards, same as in final system
  • ROACH-2 and SFP+ boards
    • Untested boards availabe ~12/10 - members of the Berkeley team are positioned to help test.
  • Ship ASIAA ADCs
• Shielded rack
  • Install UPS and filters in rack
  • Obtain ROACH2 boards
  • Obtain ADC boards
  • Obtain SFP+ mezzanine boards
    • will be added to R2 boards when shipped
  • Install and configure Roach-II chassis
    • received last pieces from shop on 12/5
  • Install switching signal dist chassis into shielded rack
    • Modify switching signal circuitry for use with Roach-II (due 12/5)
  • Install and configure network switch and fiber uplink
  • Install all optical SFP+ links to 10 gbe switch
    • Purchase qty 20 10GBase SFP+ transceiver modules
    • Purchase qty 12 LC to LC fiber jumpers

• Unshielded equipment
  • Install 10 gbe network switch
  • Install and configure 7 HPC computers
    • Reuse Test #1 (Mar) machines plus two newer ones
    • Six req. but seven will be configured
  • Configure 10 gbe ports to network switches
  • Install SFP+ NIC cards in HPCs
    • North
    • South
    • East
    • West
    • Chicken
    • vegas-hpc10
    • vegas-hpc11

• IF system
  • installed as of 12/07/12 - Install all IF input modules
    • One (two modules) can be moved now
  • Install IF module power supply chassis
  • Cable inputs from GBT IF to top of rack
  • Install 10 MHz, 1 PPS signals

• Documentation
  • Generate block diagram drawing
  • Generate rack layout drawing
  • Document modifications to switching signal dist chassis

Software

• Test 12.4 M&C system prior to pulsar observations.
  • Test Config tool modes 1 and 13 for both broadband and normal modes.
    • If the config tool features specified in https://safe.nrao.edu/wiki/bin/view/GB/Software/ModificationRequest3Q212 are required, then this MR must be tested and approved and then patched into the 12.4 system prior to the Dec 21st . The sponsor for this MR is FrankGhigo.
• Test manager for ROACH2 compatibility:
  • Fix data taking problem with ROACH1. Manager cannot get data with lates vegas_devel, this is not necessarily a ROACH1 problem.
  • When the above problem is solved, test to ensure it stays solved with ROACH2. (Need a .bof file for ROACH2.)
  • Test, and possibly fix, for problems with I2C interface on ROACH2
    • Need to know default settings for IF filters
  • Test KATCP interface for compatibility
  • (optional) modify serial port interface for synthesizer. Not really needed for Dec 17 tests, so low priority.

Firmware (DSP designs from Berkeley)

• Final testing of SFP+ with BOF files and R2 in GB
• Mode #13 will be tested if time exists
  • After Mode #1 switching has been tested
  • Working on packet sending issue (R2)
  • will ask for test time for Mode 13
