If you obtain the 'unable to connect' from one, or more, of the FEE64s try the
following procedures *before* power-cycling/rebooting all of the FEE64s:

1) 'unable to connect' whilst DAQ is going using the Merger
   
   https://elog.ph.ed.ac.uk/AIDA/303

2) determine whether multiple FEE64s are unable to connect

If you find that you are unable to ping a group (or groups) of 8x FEE64s
it is probable that the issue is a fuse failure(s) in the USB-controlled
ac mains relay. It will be necessary to replace the fuse(s) and perform a
cold start of the FEE64s

 https://elog.ph.ed.ac.uk/AIDA/418

3) If you are able to ping all FEE64s telnet to the FEE64 you are unable to
connect to, login as root, and issue a reboot command

09:33 DAQ still running, file R4_11. 
      Bias/leakage ok (attachment 1)

      Leakage currents whilst still acceptable are up around 400nA on yesterday
      Have checked all detectors and rates and pulser peak widths are still good across the board
      Will keep an eye on but for now it appears to be ok
      BRIKEN is currently doing a Cf source test so could be a result of charging from the source

      Threshold changed back to 100 from 10
      Pulser on at 2Hz

16:34 Stopped R5 alpha run
      Lowered thresholds to 0xa to produce higher rate data to test AIDA<->BRIKEN synchronisation
      Started file R6 to do this
      DAQ crashed on start ASIC readout with unable to connect to nnaida19 message appearing.
      Could not clear despite attempts at restarting the merge if that was the cause.

      FEE power cycle

17:03 DAQ recovered, R7 started
      AIDA did not crash
      BRIKEN started Ge fill cycle

      Run Control is non responsive
      Leakage currents okay - attachment 1

      Unable to ping any of the nnaida FEEs
      Restarted merger in an attempt to clear links still no response.
      Have powered down FEE64
      
      Replaced blown fuse
      Checked temperatures of FEEs, all okay - attachment 2
      

10:19 Restarted alpha run, write to file Oct18/R4.

October 25th:
In anticipation of losing access in the evening on arrival at RIKEN the following was done:
- Chiller was refilled
- All power cables reconnected after being removed in October for the RIKEN power down
- All NIM bins, fan trays and RPis were turned on
- 50MHz AIDA clock was set up and connected
- Remote connections to AC Mains relay and RPi for CAEN bias was tested
- Chiller was powered up

October 26th:

11:31 Still have access to the F11 area due to a bigRIPS delay.
      Double checked wiring from yesterday and all still seems good
      Chiller is still running with set point at +20 deg C 

11:36 FEEs powered up. All 24 mounted

11:57 Bias and leakage currents all ok - attachment 1
      FEE temperatures all ok - attachment 2
      System wide checks all ok

13:26 Bias and leakage currents ok - attachment 3

14:00 Stats are ok - attachment 5
      Appear similar to last time: https://elog.ph.ed.ac.uk/AIDA/747
      However FEE24 and 24 appear much noisier than last time with rates around 100k

19:24 Pulser walkthrough run from 90000 to 10000 in steps of 10000 for R2
      Opened file Oct18/R3, alpha run, threshold at 100kev, pulser on.
      

Data was analysed using offsets calculated based on pulser walkthroughs carried out in June 2018
Offsets appear to still be good. Ex V Ey plots - attachment 1

Hit pattern across the FEEs looks good - attachment 2
x axis is (FEE-1)*64 + Channel

No obvious dead areas in x vs y plots either - attachment 3
