MAPMT FEE (red) trouble from "Read from all Boxes":

  1. do a "Master Reload" on MAPMT FEE GUI (takes order of 9 min for load~1 min, write~4 min and read ~ 4 min) ... or more quickly just do "Master Reload" for the appropriate block of sectors -- select from the MAPMT FEE top level GUI (e.g., sectors 12-3, or 4-7, or 8-11 does just 1/3 of the detector at a time, corresponding to 3 dual power supplies as indicated on GUI).

  2. if configuration or communication indicator fails (RED) for individual boxes:

    1. pull up individual screen and try to reset box by reloading FPGAs (lower right button) ... follow this by "load", "write" and "read". It may be necessary to repeat a few times.

    2. if errors continue (e.g., HDLC communication) it is likely the box has lost its initial configuration download and this will have to be downloaded again.

      1. one can check if this is really the case by typing at VxWorks monitor prompt: smdReConfig "channel","node" (channel and node are given for you at left/top of individual box GUI). If last line it spits out contains "DONE=0", box requires download.

      2. the download can we accomplished with the "mapmtDownload" buttons at the bottom of the individual MAPMT box screen. In general it is the rdo.bit file that needs downloading and this will be sufficient (a separate "mapmt_fee.bit" usually not required). The download takes several minutes (one can chart progress on the VxWorks monitor) ... at the GUI the indication the download is done is that the box monitoring process starts again.

      3. after download, go back to sequence 2.1 above: "reload FPGAs", "load", "write", "read". Box should now configure without errors and status will turn green.

      similarly continue with the reset of any other boxes with "red" problems until all are recovered.

    3. if any MAPMT FEE boxes have "tripped" off, a "Master Reload" is required after resetting the LV power for the affected sectors.

    4. when in doubt, consult an EEMC expert! Temperature problems and other issues can add complexity to the diagnosis and subsequent action plan.
