Interface Configuration Guide 7705 SAR Interfaces
Edition: 01 3HE 11011 AAAC TQZZA 23
The 7705 SAR-M (all variants), 7705 SAR-H, 7705 SAR-Hc, 7705 SAR-A (both
variants), 7705 SAR-Ax, 7705 SAR-W, 7705 SAR-Wx (all variants), and
7705 SAR-X have a fixed physical configuration and each router uses only one
control and switching functional block, which is referred to on the CLI as CSM A. The
CSM and IOM do not need to be provisioned in order to provision the interface at the
adapter card level.
The slot ID (1) is used as part of the adapter card and port identifier on the CLI.
3.1.2 Configuring Adapter Cards and Modules
This section contains information on the following topics:
• Provisioning Chassis Slots for Adapter Cards
• Maximum Number of Adapter Cards in a Chassis
• Evolution of Ethernet Adapter Cards, Modules, and Platforms
• Channelized Adapter Card Support
3.1.2.1 Provisioning Chassis Slots for Adapter Cards
A chassis slot and card type must be specified and provisioned before an adapter
card can be provisioned. A chassis slot is a physical slot designated with an MDA ID.
On the 7705 SAR-8, the MDA ID is from 1 to 6. On the 7705 SAR-18, the MDA ID is
from 1 to 12 for the MDA slots and from X1 to X4 for the XMDA slots. An adapter card
is provisioned when a card designated from the allowed adapter card types is
inserted. A preprovisioned adapter card slot can remain empty without conflicting
with populated slots.
The adapter cards can be installed in the chassis in any combination that does not
exceed the maximum number. However, network applications require at least one
network-capable adapter card to be installed as part of the mix.
Once installed and enabled, the system verifies that the installed adapter card type
matches the configured parameters. If the parameters do not match, the adapter
card remains offline.
