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 on page 77. For installation instructions for switch fabric modules, see the installation chapter that is
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.
Replacing a fiber-optic transceiver
You can replace a fiber-optic transceiver in a 10 Gigabit Ethernet port while the device is powered on and running.
