Replacing A Switch Fabric Module - Brocade Communications Systems MLX Series Installation Manual

Replacing a switch fabric module

For 16-slot routers, if you insert a module into a slot where the fan speed for a previous module was manually configured, you will need to
change the fan speed back to auto. For example, if the fan speed was manually configured to "slow", and you are installing a module that
requires more cooling power, the "slow" setting will cause the module to overheat. To configure the fan speed to auto, enter the following
command:
# set-fan-speed auto
Brocade
Syntax: set-fan-speed auto
Due to the high cable capacity of 32-slot routers, cable bundles can be very dense. The design of the cable management system allows
you to access interface modules in the top row of the upper card cage without having to disconnect cables from the bottom row of the
same card cage. Simply move the cable bundles from the lower card cage to the side, as shown in

Replacing a switch fabric module
You can replace a switch fabric module while the router is powered on and running. For more information on switch fabric slot locations,
refer to "Switch fabric modules"
appropriate for your router model.
If you are hot-swapping a component, please allow a minimum of two seconds after the old component
has been removed before inserting a replacement component in the same slot.
For a graceful shutdown of the links, it is recommended that you disable the switch fabric module before removing it from the device. It is
also recommended that you remove or replace switch fabric modules one at a time. If you need to remove all of the switch fabric modules
at the same time, you must shut down the router and remove the power source.
