Hi tuanla,   the Fan is hot-plug not hot-swap which means you could add a Fan when the system is running but not remove it during the system is running.   Did you have any further questions?   Regards Martin
Hi, I read the spec of R650, there is Hot-plug redundant cooling feature. But I can not find the guide to hot-plug fan in the guide. With Safety Instructions, we need to power off the server before replacing the fan. Anyone can have me to clear that? Thanks so much.
