Many services down when added new SLQ4 board in OSN 3500, after that board deleted & services again provisioned to restore for the same.
Some AU_AIS, R_LOS reported. As the services were working on the 4&5 ports of 14-N1SLT1 board. We found there was R-LOS alarms reported on these channels at that time
If the same kind of problem persists, like by adding any new board if some services affect then first we need to check the slot & version compatibility.
Check the version for the GSCC board and SLQ4 board:

ExtBios 09.09.46T02 20060810 11:58:38 active

From the Hardware Description document (SE0000249602) of R6 version, we know the SLQ4 board can not be added at slot 15 on R6 version. So, it is a risk when they are running together.
For adding new board in to any equipment, first we need to check the slot & version compatibility & then insert.
