Bcu crate #5 of unit A was found not responding to the ping.

The FASTLINK communication is ok that means NO PROBLEMS with BCU ITSELF BUT more PROBABLY ETH CONNECTION.

TOTAL 20 minutes working as yesterday. Damage of eth chip????

Test on unit A: the light seems to arrive so the TX can be ok. It means that the problem can be related in RX.

Switch UP unit @ Thu Sep 1 22:53:09 CEST 2011 ----> NOT WORKING

Proceeding with shimming of interferometer.

Test on unit B purposed by Roberto done by Micheal.

Identified actuators affected by 528DSP vulcano effect: DSP[523, 529, 532] removed from ICC

AdSec 672B interferometer optical alignment

HP position at manual alignment

[0, 0, 4.5, 30, -20, 0]

M3 Position at manual alingment

[ 600, 200, 0]. Selection =-48.35

The mirror image is a bit outside the frame. Moving M3 might solve. tested negative tip offset result encouraging.

A tip offset of -100 corresponds to hp delta movements of [-0.1 0 0 50 -5 0]

M3 tip position with full pupil within the frame: -900 ,200 0

HP= [-2, -0.22, 4.5, 480, 157, 0]

FInal HP position at alignment

HP= [1.37, 0.64, 4.69, 396.67, 506.8, 0] Coma free pointing value: tip=1.4. -0.2

M3 -900, 200
