Configuration Overview; Chassis Slots And Cards - Alcatel-Lucent 7750 Configuration Manual

Configuration Overview

NOTE: This document uses the term preprovisioning in the context of preparing or preconfiguring
entities such as chassis slots, cards, input/output modules (IOMs)/Control Forwarding Module
(CFM/IOM) cards and media dependent adapters (MDAs), media dependent adapters (MDAs),
compact media adapters (CMAs), 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 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. 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/CMAs 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 off line. A
preprovisioned slot can remain empty without conflicting with populated slots.
SR-7/SR-12 and ESS-7/ESS-12 systems accept Input/Output Modules (IOM) cards. These IOM
cards have two slots which accept MDA modules. The SR-c12 and SR-c4 systems do not accept
IOMs. SR-c12 and SR-c4 systems accept MDAs using an MDA Carrier Modules. SR-c12 and SR-
c4 systems also accept Compact Media Modules (CMAs) directly without the need for MCMs.
Refer to the appropriate system installation guide for more information.
