SCM Overview

Verilink SCM 1-3

NOTE:

ecause the database resides in the SCM module, an SCM

moved to a different node without having its database first

cleared will reconfigure the new node. Take care not to cause

unintended configuration effects when swapping or moving

SCMs.

SCM as a

Gateway

The SCM is responsible for managing all the slots within the node.

All communication between the SCM and the slots use the

backplane bus. Additionally, the SCM acts as a gateway for

management traffic passing between the slots and the optional

Node Manager software package.

Database

contains the configuration and circuit information for the entire
