PTX5000 Component Redundancy on page 8
The PTX5000 is designed so that no single point of failure can cause the entire system
to fail. The following major hardware components are redundant:
Switch Interface Boards (SIBs)—The PTX5000 has nine SIBs. All nine SIBs are active
and can sustain full throughput rate. The fabric plane can tolerate one SIB failure
without any loss of performance. See
on page 91.
Host subsystem—The host subsystem consists of a Routing Engine functioning together
with a Control Board. To operate, each host subsystem requires a Routing Engine
installed in a slot in the Control Board. The PTX5000 can have one or two host
subsystems. If two host subsystems are installed, one functions as the master and the
other functions as the backup. If the master host subsystem (or either of its
components) fails, the backup can take over as the master. See
Subsystem Description" on page
If the Routing Engines are configured for nonstop active routing, the backup Routing
Engine automatically synchronizes its configuration and state with the master Routing
Engine. Any update to the master Routing Engine state is replicated on the backup
