Power on sequence - 1 2 3 Mezzanine - attachment 3
1 - FEE64 and ASIC mezzanine cooling fans
2 - FEE64 +6.2V/+6.8A
3 - FEE64 -6.5V/-0.69A, +8V/+0.88A
4 - Mezzanine +5V/+1.7A +7V/+0.03A

At power up ASIC mezzanine +5V/+2.1A which decreases to +5V/+1.7A following DAQ SETUP

Pulser to *all* inputs via test adaptor PCB (PJCS design)

Examples of test signals as follows:

Data Ready DRDY (blue), Address bits A0-A3 (magenta), pulser (yellow) - attachments 4-7

MUX Out (magenta) - attachment 8

LEC fast comparator (magenta) - attachment 9

Preamp output (magenta) - attachment 10

Following power up and the boot of the embedded PowerPC processor

DAQ RESET
DAQ SETUP
DAQ GO
Start ASIC Readout
*multiple* Check ASIC Load for ASIC #2 (note this check loads all ASICs)

Use DSO scope probe at MezzX PCB test points - attachment 11

All ASICs of the following ASIC mezzanines tested OK
