Assembly of the data concentrator pc

Marc, Michael

We installed the myricom and irig-b cards inside the data concentrator pc at respectively the cpu slot 7 (PCIe 3.0 * 8) and cpu slot5 (PCI-e 3.0 *8).

We had to change the mounting bracket of the irig-b card to fit in the back io of the pc.

The cpu slot 3 was already occupied with the hard disk controller (we had 32 TB available and extra few slots if necessary).

Note that to install (or remove) the myricom card it is required to first remove the SFP connectors.

We plan to connect the irig-b card to the gps receiver because we could not find the 'lightning stopper' box that is supposed to be at the end of the gps cable.

We also tidy up the rack we plan to use (closest to input chamber).

There are 2 smart ups at the bottom of the rack that were not connected. It could be useful in case of power shortage but we have to test them beforehand as they were made in 2005.
