•
In the event one of the route processors becomes unavailable due to failure or for software upgrade, the
secondary route processor takes over with zero boot time. To support switching fabric availability, an
optional third switch processor, running in standby mode, takes over if one of the other switch processor
cards fails. Finally, the optional network clock modules are able to retain clock configuration should one
of the modules fail.
