Hardware Overview
This section provides information on the hardware components that comprise the HDD feature in the ASR 5x00.
The HDD functionality takes advantage of the Hard Disk available in the System Management Card (SMC) of the ASR
5x00. The System Management Card (SMC) serves as the primary controller and is responsible for initializing the entire
system, and loading the software’s configuration image into other cards in the chassis as applicable. SMCs are installed
in the chassis slots 8 and 9. During normal operation, the SMC in slot 8 serves as the primary (Active), while the SMC
in slot 9 serves as the secondary (Standby).

Each SMC contains an enterprise-class Serial Attached SCSI (SAS) hard disk to load and store configuration data,
software updates, buffer accounting information, and store diagnostic or troubleshooting information. Space for CDR
storage in the internal Hard Disk is 100 Gigabytes (GB). Redundant control mechanisms allow for data to be written to
the hard disks on both the active and standby SMCs.

Important:
No hardware changes (PSC, SMC, chassis, etc.) are required to enable the CDR Storage and
Retransmission. However, an appropriate software version has to be loaded in the ASR 5x00.
