1.0 OVERVIEW
The iConverter®Network Management Module (NMM) is the heart of the iConvertermanagement system.
It features a 32-bit, high performance RISC microprocessor executing a realtime operating system. It
supports the SNMP and Telnet protocols and is capable of controlling up to 19 managed chassis.
The NMM delivers Operations, Administration and Maintenance (OAM) services for carrier-class network
access with comprehensive provisioning and network monitoring. The NMM features IP-based and IP-less
management of iConverter modules within the management domain (modules and chassis connected to the
NMM). IP-less management includes IEEE 802.3ah OAM and Omnitron’s Secure IP-less OAM management
When managing high-density fiber connections in a Central Office or network core, the NMM clusters up
to19chassis into asingle IP address. In thisconfiguration, NMM moduleswithin each chassis areconnected
to each other over a daisy chain connection.
The NMM polls all converters and power supplies within its domain, continuously collecting status and
module information. It reports its collected status via the SNMP protocol to element management
applications, such as Omnitron’s SNMP-based NetOutlook™Management Software
NOTE: It is recommended that the revision of firmware on the NMM be the same or greater than
any other management module installed in the chassis or connected remotely to installed modules.
IMPORTANT
Thismanual provides informationon the installationandconfiguration ofthemodule using thecommand
line interface (serial console). For ongoing network management, Omnitron Systems recommends
NetOutlook, an SNMP-based Network Management Software.
NetOutlook provides an efficient, user-friendly way to configure, monitor and manage devices installed
on a single network or on a series of networks by providing an intuitive graphical display with real-time
status and alarm (trap) information. The user can easily manage iConverter equipment on a large
Enterprise network or Metropolitan Area network (MAN) from a single location without the need of
additional resources.
Release 3.4 supports SNMPv1, SNMPv2c and SNMPv3.

2.0 PORT STRUCTURE
2.1 OVERVIEW
The Network Management Module front panel provides the access to the Management ports. Management
can be accessed through the serial port or the UTPport. The module features a backplane Ethernet port for
connectivity to adjacent modules.
Serial Port
Daisy Chain Port
UTP Management Port
2.1.1 Serial Console Port
The NMM features a Serial RS-232 Console Port (aka Craft Interface) for the initial setup and configuration
described in this manual. The Serial Console Port is accessed through the DB9 female DCE interface.
2.1.2 Daisy Chain Ports (Multi-Chassis)
The NMM provides a pair of redundant ports to daisy chain (cascade) up to 19 chassis providing single IP
address management.
Multi-ChassisConfiguration
To configure a set of chassis for a multi-chassis configuration, the following requirements must be followed:
• Only one NMM per chassis
• No other management modules can be installed in the chassis (i.e. 10/100M, GX/TM, etc.)
• Each NMM must have a unique chassis number (see Section 3.4.1.3)
• Remote OAM must be disabled (see Section 3.4.3.2)
Page 4

The illustration below shows how multi-chassis are managed using Omnitron’s NetOutlook Management
Software. From the chassis view screen, each of the chassis are available.
NetOutlook Chassis View
Multi-chassisconfiguration can alsobemanaged through theserial console port. Fromthe ChassisSelection
section of screen, each of the chassis connected together are available. See Section 4.0 for detailed menu
screens.
2.1.3 UTP Management Port
The NMM features a front-panel 10Mbps Ethernet management port to facilitate SNMP management of
iConvertermodules in a2, 5 or19-Modulechassis. Front-panel (Out-of-Band)managementis accomplished
by attaching a Category 5 UTP or better cable to the Ethernet front-panel management port.
2.1.4 Ethernet Backplane Port
The NMM also features a 10Mbps Ethernet backplane port. The backplane port A allows Ethernet data
connectivitybetweenthe adjacent module inthechassis. The backplane port providesIn-Bandmanagement
connectivity between the NMM and the adjacent module when both have their backplanes enabled.
Management traffic from the adjacent module transverse the backplane to the NMM.
The backplane port can be disabled or enabled via an on-board slide switch. The NMM supports Backplane
Port A only.

3.4.5 Access the NMM Remotely
Remote access to the NMM is provided via SNMP, Telnet, FTP or an external serial modem connected to
the Serial Console Port.
3.4.5.1 Accessing the NMM via NetOutlook (SNMP)
The NMM can be remotely accessed by SNMP-client software such as Omnitron’s NetOutlook SNMP
Management Software or third-party SNMP management software. See SNMP Preferences on how to
configure the required parameters.

3.4.5.2 Accessing the NMM via Telnet
The NMM is shipped from the factory with Telnet enabled. The default Telnet password is “public”. It is
highly recommended that the network administrator set a new Telnet password in order to prevent
unauthorized access to the unit. Telnet configuration parameters are available from the IP and Control
Preferences screen, option 6.

UPDATE: Are you sure? (Y/N) > Y
Please Xmodem file now:
From the terminal program, use the Xmodem protocol to send the new NMM-xxx.bin firmware file to the
NMM (where xxx represents the release level of the software).
Once the file transfer begins, the data uploads to the NMM. The process takes about five minutes over a
serial connection.
When the upload is complete, the NMM displays the update status and then automatically restarts with the
newly loaded firmware.

3.4.5.4 Updating the NMM Firmware via FTP
Using an FTPapplication, upload the new firmware into the FTProot directory of the NMM. When the file
transfer is complete, the NMM verifies the file and then automatically restarts with the newly loaded
firmware.
For detailed instructions on updating the management modules and other modules in the same chassis via
FTP, download the application note “iConverter Management: Updating Modules via FTP” available on
Omnitron’s web page:
http://www.omnitron-systems.com/downloads.php
See Setting NMM Passwords, Section 3.4.1.4, on how to configure FTP.
3.5 VERIFY OPERATION
Once the module has been installed and configured, per Sections 3.2 - 3.4, verify the module is operational
by viewing the status of the LED indicators. The table below provides a description for each indicator.
The Power LED indicates the module is receiving power from the chassis. The NMM has an LED indicator
for each available power supply in the chassis (19-Module Chassis has three, 5-Module Chassis has two).
The Master/Slave and Management LEDs indicate the operation and configuration of the management
channel. A blinking “Mgt” LED indicates the NMM is polling the chassis.
The UTP “Lk/Rx” LED indicates the module has established a connection across its UTPport. Ablinking
LED indicates the presence of data.
Refer to Section 6.0, Troubleshooting Guide, for help in determining possible fault conditions.
