SCM Overview
Verilink SCM 1-3
NOTE: B 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.
