NOTE
Brocade MLX Series and NetIron XMR router switch fabric modules are dedicated, which means that they function properly in
these routers only. If you attempt to install a Brocade MLX Series or NetIron XMR router switch fabric module in another Brocade
device or a switch fabric module intended for another Brocade device in a Brocade MLX Series or NetIron XMR router, the router
and switch fabric module will not function properly.
