Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 87)

Rebooting a modular chassis
A chassis reboot brings up the system in sequential phases. First, software services are launched on
the management modules and brought up to the active state. Then, the line cards are powered on and
initialized. Software services are launched on the line cards and brought up to the active state. When
the line card initialization reaches the final state, the chassis is ready to accept user commands from the
CLI interface.
During the boot process system initialization, configuration data (default or user-defined) are applied to
the switch through configuration replay. For more information, refer to
Managing configurations across
redundant management modules on page 107.
• On a modular chassis, the reboot and the fastboot commands only reboot the management module
on which the command is executed. If you log in to the switch IP address and execute one of these
commands, only the active management module reboots and POST is bypassed.
• The ha chassisreboot command performs a "cold reboot" (power off and restart) of the entire
chassis. If the power-on self-test (POST) is enabled, POST is executed when the system comes
back up.
Troubleshooting switches
This section presents an overview of a variety of techniques for capturing data and system messages,
which can be helpful in interactions with technical support.
Capturing and managing supportSave data
If you are troubleshooting a production system, you will have to capture data for further analysis or send
the data to your switch service provider. The copy support command provides a mechanism for
capturing critical system data and uploading the data to an external host or saving the data to an
attached USB device.
Uploading supportSave data to an external host
To upload supportSave data interactively, enter the copy support-interactive command and provide
input as prompted. Specifying an IPv6 address for the server requires Network OS v3.0.0 or later. For a
non-interactive version of the command, refer to the Network OS Command Reference.

Saving supportSave data to an attached USB device
You can use a Brocade-branded USB device to save the support data. The Brocade-branded USB
device comes with factory-configured default directories and interacts with the Network OS CLI.
