10 Prototype boards with red front panels were manufactured in early 2009. These boards are not identical to the production boards because they have a smaller FPGA. The production front panels are marked "DCC2" and are black.

Boards are numbered in decimal starting with 2001 for the first prototype up to a maximum possible number of 2255. The first digit is always '2'. The other three digits represent the decimal equivalent of the binary value set by cutting jumpers on the PCB.

You can find out which board is where in the pit as follows:

(log on to a head node, i.e. cmsusr1 etc)

$ cd ~ehazen/GetStatus
$ ./getAllVersions.sh | ./parseVersions.pl

Changes:

Confirmed that 2153 has bad LRB3 memory

-- PhilLawson - 26 Jan 2012

Much eLog sifting to bring list up to date:

-- PhilLawson - 25 Jan 2012

S/N 2159 fails LRB4 link/memory test in the pit as FED 713. PDL discovered that these spigots are not in use on this FED and opted not to swap out.

-- EricHazen - 18 Aug 2011

S/N2163 LRB0 memory chip replaced. OK now. -- Main.Shouxiang Wu - 2 Aug 2011

S/N 2172 showed CRC errors on LRB FPGA serving spigots 12,13,14. Replaced in USC on 12 Jul 2011. Installed in 904 and powered up to find all LRB chips reporting appropriate FW versions.

-- PhilLawson - 19 Jul 2011

Ship 2179 and 2183 to FNAL and MN, respectively. Track# 1Z0159190193593478 and 1Z0159190190690681

-- EricHazen - 12 May 2011

Phil tested SN 2145 at CERN as follows:

Installed HCAL DAQ version 10.4.6 (unrelated, needed for different test)
Altered FedkitTest_LTClistenToTTS_from_slot20 to take SLINK data from slot 20.
Blasted high rate events at DCC. Due to SLINK readout (with only CRC error checking), 
  effective rate was limited to 34 kHz since this DCC was providing TTS signal.
Readout 10E6 events at this rate with no SLINK errors. Good enough for me.

-- PhilLawson - 24 Jan 2012

  • Replaced line for 2151. This was accidentally removed during an edit a long while back. Good thing for twiki history!

-- EricHazen - 01 Apr 2011

-- PhilLawson - 26 Jan 2011

  • Updated list to reflect install of SN 2141 as FED 701 to replace sick DCC SN 2152.
    • SN 2152 evidenced communication problems between LRB and Event Builder chip
    • Details in eLog: 402680 on June 7 2010

-- PhilLawson - 11 Jun 2010

  • Updated list to reflect swap of SN 2142 as FED 727

-- PhilLawson - 13 Apr 2010

  • Updated list per inventory from Dick. Location with * were confirmed at CERN per Dick's 12/14/09 inventory.

-- EricHazen - 14 Dec 2009

  • Check and update a few mistakes in the list of installed DCC2

-- EricHazen - 11 Dec 2009

  • FED 719 (S/N 2145) was consistently going to OFW at 80 kHz. No events being sent down SLINK. Replaced DCC with S/N 2150

-- PhilLawson - 16 Nov 2009

  • Logged in today and found FED 700 is now S/N 2160 (was previously 2001), FED 701 is now S/N 2152 (was previously 2002)
  • Problem with FED 710 & DSP FW 0x301c described above.
