Split Dial Shelves
Cisco AS5800 Universal Access Server Hardware Installation Guide1-38
The following conditions must be met before the dial shelf interconnect port adapter is enabled:
• The dial shelf interconnect port adapter is correctly connected to the router shelf midplane and
receiving power.
• A valid Cisco IOS software image for the adapter has been downloaded successfully.
• The system recognizes the adapter.
If any of the above conditions are not met, or initialization fails for other reasons, the enabled LED
remains off.
The link LED indicates an active connection to the dial shelf. This LED lights when the dial shelf
interconnect port adapter is receiving a carrier signal from the dial shelf.
Software and Hardware Requirements
The dial shelf interconnect port adapter requires that the host Cisco 7206 router shelf is running
Cisco IOS Release 11.3(2) AA or later.
Note IOS release 11.3 (5.1) AA or later is required to support two dial shelf interconnect port
adapters. Two dial shelf interconnect port adapters are required to support dual dial shelf controllers.
Port adapters are rated by data-carrying capacity as high, medium, or low bandwidth. The host
Cisco 7206 router shelf has certain data carrying capacity (or bandwidth) restrictions that affect the
number of high bandwidth port adapters you can install. The dial shelf interconnect port adapter is
considered to be high bandwidth. Refer to the Cisco 7200 Series Port Adapter Hardware
Configuration Guidelines document that shipped with your Cisco 7206 router shelf for more
information on port adapter installation restrictions.
Split Dial Shelves
The split dial shelf configuration of the Cisco AS5800 dial platform increases bandwidth by using
two Cisco 7206 router shelves to service a single Cisco 5814 dial shelf. The dual router shelves serve
as the interfaces between the split Cisco 5814 dial shelf and the external network. This configuration
provides the equivalent of two Cisco AS5800s in a single rack. Split dial shelf configuration requires
two DSC cards and two Cisco 7206 router shelves (both with dial shelf interconnect port adapters).
For more information on hardware and software configuration needed for a split dial shelf
configuration, refer to the Cisco AS5800 Universal Access Server Split Dial Shelf Installation and
Configuration document or the Cisco AS5800 Universal Access Server Operations, Administration,
Maintenance, and Provisioning Guide, available soon.
