To reboot the switch immediately, use the following command:
reboot
If you do not specify a reboot time, the reboot occurs immediately following the command, and any
previously schedule reboots are cancelled. To cancel a previously scheduled reboot, use the
option.
Rebooting the Management Module—Modular Switches Only
To reboot a management module in a specific slot, rather than rebooting the switch, use the following
command:
reboot {time <month> <day> <year> <hour> <min> <sec>} {cancel} {warm} {msm <slot_id>}
with the additional options available:
— Specifies the slot where the module is installed
●
slot_id
—Specifies the MSM module installed in slot A

ExtremeWare XOS 11.1 introduced the concept of hitless upgrade. Hitless upgrade is a mechanism that
allows you to upgrade the ExtremeWare XOS software running on the MSMs without taking the switch
out of service. Some additional benefits of using hitless upgrade include:
Minimizing network downtime
●
Reducing the amount of traffic lost
●
Although any method of upgrading software can have an impact on network operation, including
interrupting Layer 2 network operation, performing a hitless upgrade can decrease that impact.
You must have two MSMs installed in your switch to perform a hitless upgrade. With two MSMs
installed in the switch, one assumes the role of primary and the other assumes the role of backup. The
primary MSM provides all of the switch management functions including bringing up and
programming the I/O modules, running the bridging and routing protocols, and configuring the switch.
The primary MSM also synchronizes its configurations with the backup MSM which allows the backup
to take over the management functions of the primary.
