I can only recommend the system-config-cluster GUI, but if you feel
brave enough you can do it by hand

This example is for a sanbox2, but it should get you going:
        <fence_daemon post_fail_delay="0" post_join_delay="3"/>
                <clusternode name="clusty1" votes="1">
                                <method name="1">
                                        <device name="sanbox" port="0"/>
                <clusternode name="clusty2" votes="1">
                                <method name="1">
                                        <device name="sanbox" port="1"/>
                <fencedevice agent="fence_sanbox2"
ipaddr="xxx.xxx.xxx.xxx" login="username" name="sanbox" passwd="password"/>

And don't forget to check the fence_brocade manpage for your brocade
switch for further options...
