8Replacing a switch fabric moduleFor 16-slot routers, if you insert a module into a slot where the fan speed for a previous module wasmanually configured, you will need to change the fan speed back to auto. For example, if the fanspeed was manually configured to “slow”, and you are installing a module that requires morecooling power, the “slow” setting will cause the module to overheat. To configure the fan speed toauto, enter the following command:Brocade# set-fan-speed autoSyntax: set-fan-speed autoDue to the high cable capacity of 32-slot routers, cable bundles can be very dense. The design ofthe cable management system allows you to access interface modules in the top row of the uppercard cage without having to disconnect cables from the bottom row of the same card cage. Simplymove the cable bundles from the lower card cage to the side, as shown in Figure 229.FIGURE 229Accessing the interface modules on a fully-loaded 32-slot chassisReplacing a switch fabric moduleYou can replace a switch fabric module while the router is powered on and running.
