Apparently, there are 11 chassises in the new delivery. 6 of them are installed at the site (without verifying slot 8 SNR). Only 3 chassises are tested on slot 8 and found the issue about low SNR on slot 8.
Tomorrow, THS has scheduled to go to a sites that have all 4 chassises installed to verify if the issues are on those chassises. Would you please help them investigate the issue. K'Sarawut will send out team viewer info when it is available. Thank you.
