Subject: rack reshuffle proposal for CDS upgrade 

[Tega, Jamie]

Here is a proposal for what we would like to do in terms of reshuffling a few rack-mounted equipments for the CDS upgrade. 

  • Frequency Distribution Amp - Move the unit from 1X7 to 1X6 without disconnecting the attached cables. Then disconnect power and signal cables one at a time to enable optimum rerouting for strain relief and declutter.  

 

  • GPS Receiver Tempus LX - Move the unit from 1X7 to 1X6 without disconnecting the attached cables. Then disconnect power and signal cables one at a time to enable optimum rerouting for strain relief and declutter.

 

  • PEM & ADC Adapter - Move the unit from 1X7 to 1X6 without disconnecting the attached cables. Disconnect the single signal cable from the rear of the ADC adapter to allow for optimum rerouting for strain relief.

 

  • Martian Network Switch - Make a note of all connections, disconnect them, move the switch to 1X7 and reconnect ethernet cables. 

 

  • MARTIAN NETWORK SWITCH CONNECTIONS
    # LABEL # LABEL
    1 Tempus LX (yellow,unlabeled) 13 FB1
    2 1Y6 HUB 14 FB
    3 C0DCU1 15 NODUS
    4 C1PEM1 16  
    5 RFM-BYPASS 17 CHIARA
    6 MEGATRON/PROCYON 18  
    7 MEGATRON 19 CISC/C1SOSVME
    8 BR40M 20 C1TESTSTAND [blue/unlabelled]
    9 C1DSCL1EPICS0 21 JetStar [blue/unlabelled]
    10 OP340M 22 C1SUS [purple]
    11 C1DCUEPICS 23 unknown [88/purple/goes to top-back rail]
    12 C1ASS 24 unknown [stonewall/yellow/goes to top-front rail]

     

I believe all of this can be done in one go followed by CDS validation. Please comment so we can improve the plan. Should we move FB1 to 1X7 and remove old FB & JetStor during this work?
