After loading, we have done a quick test (RECV) using a single module setup (MAC-based) to see if any large damage was there => all 13 modules were fine.
LOAD test is on-going (9/13) using a SURF-based setup to run more modules sequentially.
We run the LOAD test powering one module at a time.
For example at this time,Module 1 is on , the others are off
It takes 3 hours to test 4 modules
IV scan on mod 2
Dig/Anl scans on mod 2
Test module1 Test module2 Test module 3 Test module 4
MODULES 1-4 TEMPERATURE
We run the LOAD test powering one module at a time. However modules are warmer when a neighboring is powered.

Cooling flow
In few modules we have observed this typical pattern of bad pixels (they are disconnected bad).More investigation is needed to understand if they are real ones or something else.
