System Restart Menu
You can restart the system at any time without losing configuration
settings, except in the case of a download. When you select Execute and
then select <Enter>, a warning message informs the user that system
restart is going to be performed right now.
Warm: A warm restart restarts the hub at the runtime code.
For most cases, a warm restart is sufficient, except in the case
of a BootP request or code download.
Cold: A cold restart restarts the hub at the BOOTROM level
and is the same as unplugging and re-plugging power to the
hub. A cold restart is needed when the user performs a BootP
request or code download.
