<div class="PlainText">Hi Aaron,<br>
<br>
Just a couple updates/corrections/clarifications to the notes for Items<br>
2.3 and 2.4.<br>
<br>
[Item 2.3]<br>
I received these two modules from George and installed them in the crate<br>
in the ESB:<br>
SY4527 Primary Power Supply (ser 0640)<br>
Sy45627 Booster Power Supply (ser 0109)<br>
The original Primary Power Supply and Booster for the crate in the ESB<br>
were used as replacements for a production Hall C crate in early<br>
September (seen next item).<br>
<br>
[Item 2.4]<br>
I think the units that George must be testing are the two units that I<br>
pulled from a production Hall C crate and dropped off with you guys in<br>
early September?<br>
- SY4527 Primary Power Supply (ser 0241)<br>
- 'Vcc' lamp was off (this is not normal)<br>
- Sy45627 Booster Power Supply (ser 0051)<br>
- I swapped this out at the same time as the above unit 'just in<br>
case', but this Booster is probably fine. (I have no reason to<br>
suspect it.)<br>
<br>
More information on the modules dropped off in September can be found<br>
in the Dsg-hallc_nps archive here:<br>
