1 通过Brocade交换机自带U盘升级
1.1准备微码
将交换机微码解压缩后放到U盘的firmware目录下，注意firmware目录下只能包含一层目录，例如：brocade/firmware/v6.4.2b。
1.2用单网线通过IE升级
`将微码复制到U盘的firmware路径下，并且将U盘插到active的CP上。用一根网线连接DCX的active CP板，在IE中输入DCX的IP地址。
点击CP板上USB接口，mount USB设备
点击firmware download，选择微码文件进行升级。
升级过程DCX自动完成两个CP的切换。
3通过console升级
通过console口连接DCX的active CP。将微码保存到U盘，插在active CP的USB口。打开命令行。

This command will upgrade the firmware on both CP blades. If you want to
upgrade firmware on a single CP only, please use -s option.
You may run firmwaredownloadstatus to get the status of this
command.
This command will cause a warm/non-disruptive boot on the active CP,
but will require that existing telnet, secure telnet or SSH sessions
be restarted.

执行完上述过程后，交换机自动升级。
2 通过console升级
2.1准备升级
hashow 检验HA是否同步
ipaddrshow 检查两个CP板的IP
firmwareshow 检查两个CP板的微码版本
准备FTP server，将firmware保存到相应的目录下。
2.2升级Standby CP的firmware
"firmwaredownload -s"选择FTP服务器下的firmware进行升级，当standby CP升级完成后"firmwareshow"检验微码是否正确，如果正确"reboot"。
2.3切换Standby CP
"hafailover"切换standby CP
2.4 升级Standby CP的firmware
当原来Active CP切换为standby CP后，按照2.1升级现在的Standby CP。
2.5在Standby CP上执行commit
在现在Standby CP上执行"firmwarecommit"后，执行"firmwareshow"检验微码版本是否正确
2.6在Active CP上执行commit
在现在Active CP上执行"firmwarecommit"后，执行"firmwareshow"检查两个CP板微码是否一致并且符合要求。执行"hashow"检查HA是否同步。
