Hot-Plug Feature
Caution –
If the message:
NOTICE: Hot Plug not supported in this
system
is displayed during boot, do NOT attempt hot-plug in this system or
damage to the hardware will occur.
The hot-plug feature is the ability to insert a new board into a powered-on system,
despite being “live,” or being supplied with electrical power. Once a replacement
board is added to a powered-on system with the hot-plug feature, you must reboot
before the system can use the new board.
