Hard To Sayhow many Jb's need to be repaired/replaced. It may not be that many boxes but the ones that need replacing may be a long lead time order item. Might be 3 week delivery and a couple weeks to replace.
Depending on what system they are on will determine how much more commissioning it will take to give everyone the green light again.
Either way this is fixable and that is a positive.
You either sell/buy more or just wait it out.
Frustrating to say the least.
