Hardware Redundancy Configuration 
The maximum redundant configuration for a fully loaded system supporting data services consists of the following: 
 
  2 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 
this recommended maximum redundant configuration.
