How easy is it to swap the fan bar out for a failed fan? It looks like a single unit holding all the fans. Can the sled be pulled but retained in the rack and then fan bars removed and reinstalled without fully removing the sled and without tools?

The sleds blind mate to power and network on the backplane so removing the sled will disconnect it. Once the sled is disconnected you pull the fan assembly out and replace it.
