Document conventions
This section describes text formatting conventions and important notices formats.
Text Formatting
The narrative-text formatting conventions that are used in this document are as follows:
bold text Identifies command names
Identifies the names of user-manipulated GUI elements
Identifies keywords and operands
Identifies text to enter at the GUI or CLI
italic text Provides emphasis
Identifies variables
Identifies paths and Internet addresses
Identifies document titles
code text Identifies CLI output
Identifies syntax examples
For readability, command names in the narrative portions of this guide are presented in mixed
lettercase: for example, switchShow. In actual examples, command lettercase is often all
lowercase. Otherwise, this manual specifically notes those cases in which a command is case
sensitive.
Notes, cautions, and warnings
The following notices and statements are used in this manual. They are listed below in order of
increasing severity of potential hazards.
NOTE
A note provides a tip, guidance or advice, emphasizes important information, or provides a reference

Getting technical help
Contact your switch support supplier for hardware, firmware, and software support, including
product repairs and part ordering. To expedite your call, have the following information available:
1. General Information
•Switch model
•Switch operating system version
•Error numbers and messages received
•supportSave command output
•Detailed description of the problem, including the switch or fabric behavior immediately
following the problem, and specific questions
•Description of any troubleshooting steps already performed and the results
•Serial console and Telnet session logs
•syslog message logs
2. Switch Serial Number
The switch serial number and corresponding bar code are provided on the serial number label,
as illustrated below:
The serial number label is located as follows:
•Brocade 200E—On the nonport side of the chassis
•Brocade 300, 4100, 4900, 5100, 5300, 7500, and Brocade Encryption Switch—On the
switch ID pull-out tab located inside the chassis on the port side on the left
•Brocade 5000—On the switch ID pull-out tab located on the bottom of the port side of the
switch
•Brocade 7600—On the bottom of the chassis
•Brocade 48000—Inside the chassis next to the power supply bays
•Brocade DCX—On the bottom right on the port side of the chassis
•Brocade DCX-4S—On the bottom right on the port side of the chassis, directly above the
cable management comb.
3. World Wide Name (WWN)
Use the wwn command to display the switch WWN.
If you cannot use the wwn command because the switch is inoperable, you can get the WWN
from the same place as the serial number, except for the Brocade DCX Data Center Backbone.
For the Brocade DCX Backbone, access the numbers on the WWN cards by removing the
Brocade logo plate at the top of the nonport side of the chassis.
