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)

Changes:

Update to reflect old swap of 2144->2182 -- PhilLawson - 10 Sep 2012

Update to reflect swap of 2148->2131 due to memory failure on 2148 -- PhilLawson - 10 Sep 2012

Update to reflect unnecessary swap of 2131->2153 -- PhilLawson - 10 Sep 2012

Update to reflect switch of 2178 -> 2142 on 10 May 2012 -- PhilLawson - 10 Sep 2012

SN 2173, 2159, 2133, 2153, 2150 tested after repair -- EricHazen - 06 Mar 2012

SN 2173 fails at P5. Tested with DCC2Tool.exe and it fails LRB3. Replaced with SN 2142 as FED 705. -- PhilLawson - 24 Feb 2012

SN 2133 fails memory test on LRB2, LRB3 Changes at P5: http://cmsonline.cern.ch/cms-elog/751963 -- PhilLawson - 31 Jan 2012

SN 2145 re-checked for SLINK integrity w/ fedkit. AOK. We should install this one @ P5 to be verified with MWGR before 2012 data taking

SN 2150 fails memory test on LRB2. This matches the symptoms of the spigots that were not working at P5.

SN 2160 Tests fine on lxcmdtest3 @ 43 kHz. Then we run again at 83 kHz (no TTS), HTRs are giving single bit errors which are corrected by DCC, but no UErrs show up on spigot 13 (this was the failure mode at P5). Returning to pile of good spares. Instrumented with cables to connect scope probes to monitor 3.3V and 2.5V supplies. Need to test at P5 in fully occupied crate to look for transient spikes.

SN 2132 retest VME readout. Still does not work.

-- PhilLawson - 27 Jan 2012

SN 2132 Tested on cmsmoe4 in 904. VME readout does not appear to work. xDAQ stops after 100 events (this is how many trigger credits are issued). Event Builder hyperdaq does not show any events coming in from the DCC's FED. Wu looks at register dump and states that it appears as if the VME spy buffer was already read out. Did the events get "dropped" in software? Why only for this board? Unclear. Needs further investigation.

SN 2162 Tested on cmsmoe4 in 904. VME readout works just fine. Returning to pile of good spares

SN 2181 checks out AOK with xDAQ run on lxcmdtest3 post replacement of LRB1 (U11)

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

• SN 2163 showed CRC errors on LRB chip serving spigots 0,1,2
  • SN 2177 installed in place as FED 709

-- 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

• 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)
