Clock status test result: Passed 12, Failed 0</p>
<p>Understand status as follows<br />
Status bit 3 : firmware PLL that creates clocks from external clock not locked<br />
Status bit 2 : always logic '1' <br />
Status bit 1 : LMK3200(2) PLL and clock distribution chip not locked to external clock<br />
Status bit 0 : LMK3200(1) PLL and clock distribution chip not locked to external clock<br />
If all these bits are not set then the operation of the firmware is unreliable</p>

White Rabbit error counter test result: Passed 3, Failed 9</p>
<p>Understand the status reports as follows:-<br />
Status bit 3 : White Rabbit decoder detected an error in the received data<br />
Status bit 2 : Firmware registered WR error, no reload of Timestamp<br />
Status bit 0 : White Rabbit decoder reports uncertain of Timestamp information from WR</p>

If any of these counts are reported as in error<br />
The ASIC readout system has detected a timeslip.<br />
That is the timestamp read from the time FIFO is not younger than the last</p>

<p>At <strong>8:30</strong> DAQ and Temperature Scan stopped working properly.</p>

<p><strong>11:00</strong></p>
<p>It was noted that at the time that AIDA dropped out ~8:30 the beam also dropped out. It seems a bit of a coincidence</p>
<p>TD and MS powercycled the FEEs after the first crash and restarted MIDAS but not the merger. This recovered the FEEs but did not re-establish the links between the FEEs and the Merger.</p>
<p>Another powercycle was performed this time with a full reset of the merger and the links were restored. Upon restoring there was a large amount of noise in across all FEEs on average a 50% increase across all FEEs but in DSSD a factor of 4-6 increase was common.</p>
<p>In the waveforms large 100kHz transiets could be seen - <strong>attachment 4</strong></p>
<p>A further power-cycle was performed by OH. The rates following this powercycle are better than just before the power cycle but have not recovered to pre-glitch levels.</p>
<p>The waveforms here are much improved though - <strong>attachment 5 and 6</strong></p>
