Chapter 1 Overview and Physical Description
Fabric Controller Card
Serviceability
RSP/RP cards can be inserted or removed when adjacent (cabled) RSP/RP or line cards are installed.
Compact Flash is serviceable without the need to remove the RSP card. Servicing the hard drive requires
removal of the RSP/RP card.
RSP and RP Card Ejector Levers
Ejector levers are provided for inserting and removing the RSP/RP cards. The insertion and removal
force of the card ejector levers is about 16 lbs (7.27 kg). Longer ejector levers are provided for the
RSP/RP cards than for the line cards due to the higher pin count of the RSP/RP card.
Fabric Controller CardOn the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the switch fabric has been moved to FC
cards.
The switch fabric is configured as a single stage of switching with multiple parallel planes. The switch
fabric is responsible for transporting packets from one line card to another but has no packet processing
capabilities. Each fabric plane is a single-stage, non-blocking, packet-based, store-and-forward switch.
To manage fabric congestion, the RP provides centralized Virtual Output Queue (VOQ) arbitration.
The switch fabric is capable of delivering 550-Gbps per line card slot. When five FC cards are installed
in the chassis, the switch fabric is 4+1 redundant. When all seven FC cards are installed in the chassis,
the switch fabric is 6+1 redundant. The switch fabric is fully redundant, with one copy of the fabric on
each FC, and each FC carries enough switching capacity to meet the chassis throughput specifications.
