Configuration Overview

Configuration Overview
NOTE: This document uses the term preprovisioning in the context of preparing or preconfiguring
entities such as chassis slots, line cards (or input/output modules (IOMs) and media dependent
adapters (MDAs), ports, and interfaces, prior to initialization. These entities can be installed but
not enabled. When the entity is in a no shutdown state (administratively enabled), then the
entity is considered to be provisioned.
Alcatel-Lucent 7750 SR-Series routers provide the capability to configure chassis slots to accept
specific line card and MDA types and set the relevant configurations before the equipment is
actually installed. The preprovisioning ability allows you to plan your configurations as well as
monitor and manage your router hardware inventory. Ports and interfaces can also be
preprovisioned. When the functionality is needed, the card(s) can be inserted into the appropriate
chassis slots when required.
The following sections are discussed.

Chassis Slots and Cards

To pre-provision a chassis slot, the line card type must be specified as well as the MDA type.
System administrators or network operators can enter card type information for each slot, allowing
a range of card types in particular slots. From the range of card types, a card and accompanying
MDAs are specified. When a card is installed in a slot and enabled, the system verifies that the
installed card type matches the allowed card type. If the parameters do not match, the card remains
offline. A preprovisioned slot can remain empty without conflicting with populated slots.

MDAs

A chassis slot and card type must be specified and provisioned before an MDA can be
preprovisioned. An MDA is provisioned when a type designated from the allowed MDA types is
inserted. A preprovisioned MDA slot can remain empty without conflicting with populated slots.
Once installed and enabled, the system verifies that the installed MDA type matches the
configured parameters. If the parameters do not match, the MDA remains offline.
