Overview
The Cisco 8818-FC is the switch fabric card for the Cisco 8818 chassis. It provides the ultra-high bandwidth switching capacity needed to interconnect the line cards installed in the chassis. The 8818-FC utilizes Cisco Silicon One Q100 ASICs to deliver up to 518.4 Tbps of switching capacity with the 8818 chassis fully loaded.
The Cisco 8818-FC chassis supports up to 18 line cards. It uses 8 fabric cards in a 7+1 redundant configuration to provide sufficient bandwidth for all ports on the line cards to operate at line rate speeds simultaneously. The fabric cards are hot swappable and redundant to ensure maximum uptime.
