The optional remote Management Module occupies a single chassis

slot and provides management and monitoring access over the local

area network.  This frees the administrator from the necessity of

direct physical access to configure the system or its modules. System

Management was designed to be "plug and go" so that future

modules with additional or enhanced capabilities can be plugged

into the system without any firmware compatibility worries and, in

most cases, with no firmware updates required. Each module

contains non-volatile memory for storing user configured

management parameters and for describing the module

characteristics and capabilities to the management firmware.  The

Management Module also provides a Simple Network Management

Protocol (SNMP) agent that transmits traps and alerts when problems

or significant system events are detected.

The Management Module is shipped from the factory configured

for its networking parameters to be obtained using the standard

BOOTP protocol. If the user’s network is using a BOOTP server (or

a DHCP server that supports BOOTP devices), no manual

configuration is required for remote access.  The system will

automatically obtain its network parameters from the network server.

It will still be necessary to specify SNMP Manager parameters

because these details are not part of the standard BOOTP protocol.

However, any of the available user interface options can be used.

An important feature of Canary’s CCN-2000/CCN-0400

Management is a philosophy and System architecture that is

designed to be Operating System independent.  This independence

eliminates the expense and complexity of up-dating management

software every time a user’s network operating system (OS)

undergoes a revision.  Canary’s approach is to provide a simple,

intuitive Web interface that is easily navigated rather than a custom

graphic user interface (GUI) that risks becoming obsolete when the

OS changes.

Canary provides three Management interfaces for System

Management control and configuration.

1. Command-line User Console (out-of-band),

2. Simple Network Management Protocol (SNMP) agent, and

3. The CANARY Web Server

These straightforward interfaces require no special application

software to be installed on the remote management computer,
