High-speed switch fabric modules

NOTE
Gen-1 switch fabric modules and Gen-2 high-speed fabric (HSF) modules are not compatible and will
not operate together in the same device.
HSF modules are supported on Brocade MLX Series and NetIron XMR routers, and are
interoperable with all existing interface modules.
HSF modules are hot-swappable, which means you can install or replace them while the system is
powered up and running.
NOTE
Do not remove or power-off all switch fabric modules on MLX chassis while the device is up and
running. Removing all the switch fabric modules from the device and then re-inserting them can
cause the device to become unstable, resulting in protocol flaps and thereby traffic impact. A system
reload is required to recover.
HSF modules can operate in normal mode or turbo mode but will boot in turbo mode only if all
active interface modules are Gen-2 and Gen-3modules.

Router modules
R05.3.00 and earlier, when you insert an SFM
or during powering on the device, the Active
LED was off for a short duration, up to 15
seconds because the monitoring of the Fabric
module is stopped for this duration. After this
delay, the LED indicated the monitoring status.
In version R05.4.00 and later, the Active LED
reads the switch fabric continuously even
during module insertion or powering on the
device, and thus the Active LED blinks.
