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
Hardware Redundancy Configuration
The maximum redundant configuration for a fully loaded system supporting data services consists of the following:
2 SPCs/SMCs: 1 active and 1 standby (redundant)
14 processing cards: 13 active and 1 standby
2 SPIOs: 1 active and 1 standby
26 Ethernet/Gigabit Ethernet line cards: 13 active and 13 standby (10/100 Ethernet Line Card (FELC), 1000
Gigabit Line Card (GELC), and Quad Gigabit Ethernet Line Card (QGLC))
2 1000 Gigabit Ethernet Line Cards (XGLC): 1 active, 1 standby. Note that the XGLC, which is a full-height
line card that populates both the upper and lower slots of the chassis, uses a side-by-side redundancy scheme.
Refer to the Hardware Installation and Administration Guide for more information.

26 Optical (ATM) line cards: 13 active and 13 standby (OLC and OLC2)
26 Channelized line cards: 13 active and 13 standby (CLC and CLC2)
2 RCCs: 2 standby
This configuration allows for the highest session capacity while still providing redundancy. The following figures depict
