26 Chapter 2 Overview of BCM50 Administration
NN40020-600NN40020-600
• review logs of operational information
• retrieve and view logs containing diagnostic information in the event of a system issue
• manage system inventory
• manage software updates
• make changes to the system configuration to change service definitions or add users including
adding new features through the application of keycodes
The descriptions and procedures in this guide will assist the administrator in performing these
tasks.
The following management model demonstrates how BCM50 manageability is achieved by
breaking the management functions into layers.
At the base of the model is the element itself. In order to be a manageable system, the element
must provide not only the ability to configure services, but must also regulate access to the system
by administrative users, generate alarms in the event of issues, support the easy addition of new
features through the application of keycodes, provide a means for making a backup of the
configured data, and other administrative functions.
The management tools at the next layer provide a user interface to control these functions for a
selected BCM50 device. The primary management application for BCM50 is the Element
Manager, complemented by other management applications as explained in “BCM50
Management Environment and Applications” on page 33. For BCM releases prior to 4.0, the
management application is Unified Manager.
If the BCM50 is one of a number of elements in a network, network management tools at the
network management layer facilitate monitoring and management across the network. Nortel
provided tools such as Enterprise Network Management System (ENMS) for network monitoring,
and third party tools supporting multi-vendor networks, can only deliver their value if the managed
element itself has provided for the right functions at the manageable systems layer.
Also at the network layer, system and configuration management tools can provide support for
tasks such as bulk distribution of selected configuration information, network wide inventory
management and network wide backup management. The Network Configuration Manager
(NCM) server-based management application provides these and other capabilities for managing a
network of up to 2000 BCM50 devices. For more information about NCM, please consult the
NCM User documentation.
