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 set
fan speed auto command.
device# 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 the following figure.

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.
NOTE
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.

You can replace a fiber-optic transceiver in a 10 Gigabit Ethernet port while the device is powered on and running.
