@RobH this was an older decom task that was still open, i added the newer checklist now and checked the boxes after the fact. assigning to you to check if switch ports was done already since i know you are doing the general audit of decoms anyways. could you look and then forward to chris?

The switch port was not disabled, so glad we're adding the checklist to any open decom tasks.
