Replacing a switch fabric module
CAUTION
If you are hot-swapping a component, allow a minimum of two seconds after a component has
been removed before inserting a replacement component in the same slot.
Removing and replacing an interface module
To remove or replace an interface module, see the module instructions in the installation chapter
that is appropriate for your router model.
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:
PowerConnect
Syntax: set-fan-speed auto
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
instructions for switch fabric modules, see the installation chapter that is appropriate for your
router model.
CAUTION
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.
Before removing a fiber-optic transceiver, have the following items available:
•
162
# set-fan-speed auto
The protective covering that you removed from the fiber-optic transceiver port when you initially
installed the module
