Subject: installation of C1LSC: still going on 

 [Joe, Kiwamu]

 We tried installing C1LSC but it's not completely done yet due to the following issues.

    (1)  A PCIe optical fiber which is supposed to connect C1LSC and its IO chasis is broken at a high probability.

    (2)  Two DAC boards (blue and golden board) are missing.

 We will ask the CDS people at Downs and take some more of those stuff from there.

( works we did )

 - took the whole C1ASC crate out from the 1Y3 rack.

 - installed an IO chasis to the place where C1ASC was.

 - strung a timing optical fiber to the IO chasis.

 - checked the functionality of the PICe optical fiber and found it doesn't work.
