254 Power Management
• Power Cycle System (cold boot) — Powers off and then reboots the
system (cold boot). This option is disabled if the chassis is already
powered
OFF .
NOTE: This action powers off and then reboots the entire chassis (chassis, servers
which are configured to always power on, IOMs, iKVM, and power supplies).
• Reset CMC — Resets the CMC without powering off (warm reboot).
(This option is disabled if the CMC is already powered off).
NOTE: This action only resets the CMC. No other components are affected.
• Non-Graceful Shutdown — This action forces a non-graceful power
off of the entire chassis (chassis, servers, IOMs, iKVM, and power
supplies). This does not attempt to cleanly shutdown the operating
system of the servers prior to powering off.

the system to reset).
