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 8000 —On the switch ID pull-out tab located inside the chassis on the port side
on the left.
3. World Wide Name (WWN)
Use the licenseIdShow command to display the WWN of the chassis.
If you cannot use the licenseIdShow command because the switch is inoperable, you can get
the WWN from the same place as the serial number, except for the Brocade DCX. For the
Brocade DCX, access the numbers on the WWN cards by removing the Brocade logo plate at
the top of the nonport side of the chassis.
