Download the firmware to the switch

In preparation I downloaded the firmware package from Broadcom, extracted the archive and uploaded the extracted directory to a local SSH/SCP/SFTP server I have access to and that can be accessed by the switch.
You can also use an ftp or http server

admin> firmwaredownload -p sftp -s
Server Name or IP Address: 10.11.12.112
User Name: thor
File Name: /incoming/brocade/v9.2.2a_G7_ENTRY

Or

admin> firmwaredownload -p sftp 10.11.12.112,thor,/incoming/brocade/v9.2.2a_G7_ENTRY

You can run firmwaredownloadstatus to get the status
of this command.

This command will cause a warm/non-disruptive boot but will
require that existing telnet, secure telnet or SSH sessions
be restarted.
