ADF System  Spare Components at Fermi

                                               Initial Rev.  9-JAN-2007

To expedite the second item  "Spares Inventory"  on the agenda
for the L1 Cal Trig meeting on January 9th   I can provide the
following information to describe the spares, stored at Fermi,
for the ADF system.


There are 8 spare ADF-2 cards and 1 spare SCLD card stored at Fermi.

  - These cards are stored in the locked yellow card storage rack
    cabinet located in the fixed counting house against the wall
    that separates the FCH from the sidewalk near where my desk
    is located on the first floor FCH.

  - This yellow rack cabinet is labeled something like, "MSU L1 Cal
    Trig and TFW Spare Cards".

  - These 9 spare cards for the L1 Cal Trig ADF system are all in
    a small 6U card file near the top of this rack cabinet.  They
    are lined up in order and are clearly labeled.

  - Our records indicate that the serial numbers of the spare cards
    currently stored at Fermi are:

      ADF-2 cards SN#:  A20,  A21,  C3,  C5,  B20,  B21,  D36,  D37.

         This set contains a spare  Maestro and non-Maestro  version
         of each of the 4 species of ADF-2 cards.

      SCLD card SN#2

         This card is loaded with current SCLD firmware in its PROM.

  - All of these cards have been tested and are ready to use.

  - This spare card storage cabinet also contains cards for the
    TFW, Master Clock, and SCL Hub-End which should not be disturbed.


There is a spare ADF Crate  Power Supply Chassis  and a spare ADF
Crate  Fan Tray  stored at Fermi.

  - These two items are stored in the locked brown storage cabinet
    located in the fixed counting house against the wall that
    separates the FCH from the sidewalk near where my desk is located
    on the first floor FCH.

  - This brown cabinet is labeled something like, "MSU L1 Cal Trig
    Spare Power Supplies".

  - Both of these items are wrapped up in bubble wrap and labeled.

  - The labels include the date when these items were most
    recently tested.

  - The spare  ADF Crate Power Supply Chassis  is Wiener
    serial number SN# 5196006 

  - This storage cabinet also contains in labeled boxes the spares
    for all of the passive components that make up the BLS Cable
    Transition System  (ATC cards, Pleated Foil Cables, ...).


The same key will open the lock on either the yellow or brown
spares storage cabinets.  This key is kept hanging from a hook
on the inside of the left hand door of the gray cabinet next to
the desk where I sit on the first floor FCH.  This gray cabinet
is labeled, "MSU L1 Trigger".  The location of the key that opens
the gray cabinet has been communicated to the people who routinely
work on the L1 Cal Trig hardware and could be passed to any shifter
in an emergency.

As indicated above I believe that we have stored in cabinets at Fermi
tested known good spares labeled and ready to use for all components
in the ADF system.  These spare components have all been in place at
Fermi since early August 2006 or before.
