TABLE 25 Switch fabric module LEDs (continued)
NOTE
On devices supporting software version
R05.3.00 and earlier, when you insert an SFM
or during powering on the device, the Active
LED was o 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.
O for extended period The switch fabric is not active and cannot switch user
packets.
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 MLX Series 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-o all switch fabric modules on an MLX Series 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 aps and thereby trac 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.
CFP2 to QSFP28 conversion module
This section provides general information about the Extreme CFP2 to QSFP28 conversion module, which installs into the 2x100GbE
CFP2 optics based high density module of the MLX Series router.
NOTE
To install the conversion module, refer to instructions in section, Removing and Replacing a CFP2 to QSFP28 Conversion
Module.
The CFP2 to QSFP28 conversion module in the following illustration inserts into 100 GbE CFP2 port cages (ports) on the 2x100GbE
CFP2 optics based high density module to allow connection to 100 GbE QSFP28 ports.
