▄ Cisco ASR 5000 Series Product Overview
OL-22938-02
Service Availability Features
In its recommended redundant configuration, the system provides the highest level of service assurance. Following is
detailed information describing the service availability features found in the system.
Hardware Redundancy Features
In addition to providing the highest transaction rates and session capacity, the system is designed to provide robust
hardware reliability and service assurance features.
Features of the hardware design include:
ASR 5000
System Management Card (SMC) redundancy
1:n Packet Services Cards (PSC/PSC2) redundancy, allowing redundancy of multiple active to multiple
redundant for up to 14 total PSCs or PSC2s
Important:
1:1 redundancy is supported for these cards however some subscriber sessions and accounting
information may be lost in the event of a hardware or software failure even though the system remains operational.
1:1 Optical (ATM) line card (LC) redundancy (OLC and OLC2)
1:1 Channelized (STM-1/OC-3) line card (LC) redundancy (CLC and CLC2)
1:1 Quad Gigabit Ethernet Line Card (QGLC)
1:1 10 Gigabit Ethernet Line Card (XGLC)
1:1 Switch Processor I/O (SPIO) card redundancy
1:1 10/100 Ethernet Line Card (FELC)
1:1 1000 Gigabit Ethernet Line Cards (GELC)
Configurable line card port redundancy (Ethernet, ATM, and SPIO line cards)
Redundancy Crossbar Card (RCC) for processor-card-to-line card failover using the 280 Gbps Redundancy Bus
Self-healing redundant 320 Gbps switching fabric
Redundant 32 Gbps Control Bus
Redundant Power Filter Units (PFUs)
Hot-swappable cards, allowing dynamic replacement while the system is operational
