Router Maintenance
Hardware maintenance schedule
DANGER
The procedures in this manual are for qualified service personnel.
Dell routers require minimal maintenance for hardware components. It is recommended that you
perform the following regular maintenance tasks:
•
Clean the fiber-optic connectors on a fiber-optic transceiver port and the connected fiber cable
each time you disconnect the cable.
•
Replace the air filters quarterly.
You can also replace the following hardware components, as needed:
•
All modules (management, interface, and switch fabric).
•
Fiber-optic transceivers.
•
AC power supplies.
•
Fan assemblies.
NOTE
The management, interface, and switch fabric modules are dedicated, which means that you must
install them in Dell routers only. If you install these modules in another Dell device or you install a
module intended for another Dell device in a Dell router, the device and modules will not function
properly.
Replacing a management module
For instructions on how to install or replace modules, refer to the module installation section in the
installation chapter for your router model.
Replacing an interface module
You can remove or replace interface modules while the router is powered on and running. For more
information on module slot locations, refer to
Chapter 1, “Product Overview” . For information about
how to install a new or replacement module, refer to the installation chapter for your router model.
