PTX5000 Component Redundancy
The PTX5000 Packet Transport Switch 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 Packet Transport Switch 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 “PTX5000 Switch
Interface Board Description” on page 48.
•
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 packet transport switch 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
