Checklist for the draft of the paper†

tube42 is back (2012.1.30)

• person in charge: nugraha, helped by hasdeo and tapsanit
• target: move motherboard of oldflex which is originally tube42's motherboard

procedures†

1. preparation:
   • check the components of tube42: harddisk OK, power supply OK, special shaped cable OK, LED cable is matched with the other tube40's series
2. oldflex is turned off
   • remove all cables from the old flex box
   • remove the motherboard from the old flex
   • the empty box is kept at room 947
3. tube42 box is taken from tube40 big box
   • fan is turned off, other tube is turned off
   • motherboard can be put on the tube42 box
   • problem: oldflex motherboard screws do not match with the tube42 box
   • solution: use the appropriate screws from room 947 -> OK
   • plug in all the necessary cables correctly (HD, power, LED)
   • put again the tube42 box above tube41
   • connect network cable, display cable, mouse, keyboard.
   • turn on all the machines and fan.
   • close the box.
4. how to check it works?
   • from tube42: log in with root or your account
   • from flex

     ssh tube42

5. cpu fan checking
   • log in as root in tube42
   • type following command to check initial temperature of all cpus

     sensors

   • open another terminal, then log in to tube42 using your account
   • run the program in your account
   • in the previous terminal, type the same command to monitor the temperature while the program is running.
   • check the temperature of cpu when the program is finished, the temperature should decrease indicating that the heat is being moved out from the cpu.
   • following is the result of checking: The temperature of all cpus is recorded after running of exciton program for 30 min. (+30). When the program is stopped for 30 min (-30), the temperature is also recorded. The decreasing of temperature of cpu indicates that the cpu fan is working correctly.
