MM removal Warm failover to standby MM.
Power cycle MMs will retain the HA roles upon booting up.
Disabling and enabling a chassis
The chassis is enabled after power is turned on, and diagnostics and switch initialization routines have
finished. All interfaces are online. You can disable and re-enable the chassis as necessary.
• Use the chassis disable command if you want to take all interfaces offline. If the switch was part of
an Ethernet fabric, the fabric reconfigures.
• Use the chassis enable command to bring the interfaces back online. All interfaces that were
enabled before the chassis was disabled are expected to come back online. If the switch was part
of an Ethernet fabric, it rejoins the fabric.
NOTE
Disabling the chassis is a disruptive operation. Use the shutdown command to disable or enable a
few selected interfaces only. Refer to the Network OS Command Reference for more information on
this command.
Rebooting a switch
Network OS provides several commands to reboot your system: reload, fastboot, reload system,
and ha chassisreboot.
CAUTION
All reboot operations are disruptive, and the commands prompt for confirmation before
executing. When you reboot a switch connected to a fabric, all traffic to and from that switch
stops. All ports on that switch remain inactive until the switch comes back online.
Rebooting a compact switch
• The reload command performs a "cold reboot" (power off and restart) of the control processor (CP).
If the power-on self-test (POST) is enabled, POST is executed when the system comes back up.
• The fastboot command performs a "cold reboot" (power off and restart) of the control processor
(CP), bypassing POST when the system comes back up. Bypassing POST can reduce boot time
significantly.
CAUTION
Do not perform a reload command between a chassis disable command and a chassis enable
command. Your ports will be closed.
