1.0 OVERVIEW

This document describes the installation and configuration of the iConverter 2GXM standalone Network Interface Device and plug-in modules. The difference between the module types are indicated using the following legend throughout this User Manual:

- Standalone

- Plug-In

1.1 GENERAL DESCRIPTION

The Omnitron iConverter® 2GXM Network Interface Device (NID) with integrated management provides Gigabit Ethernet (1000BASE-X) fiber-to-fiber media conversion. It is also a managed optical switch that functions as a fiber repeater performing the Three Rs: Retiming, Reamplification and Reshaping of the fiber optic signal.

The 2GXM conforms to Ethernet in the First Mile (EFM) fiber standards to support Fiber-to-the-X (FTTX) Metropolitan and Enterprise LAN networks. 2GXM NIDs are used to provide managed demarcation points at the customer premises and network edge, offering Quality of Service capabilities.

The IP-based remote management of the 2GXM can be accessed by Omnitron’ s NetOutlook® SNMP Network Management Software, third-party SNMP clients and Telnet. The management IP address is configured manually or as a DHCP client in the configuration menu. IP-less remote management is supported via

802.3ah OAM or Secure OAM protocol. A menu-driven CLI is accessible via Telnet, serial console port, or a modem connection to the serial console port.

IMPORTANT

This manual provides information on the installation and configuration of the module using the command 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.

The firmware of the Network Management Module (NMM) and NetOutlook must be the same or greater than the firmware on the 2GXM for the module to be managed.

1.1.1 Advanced Features

The 2GXM features Port VLAN, Tag VLAN, Provider VLAN and QoS prioritization which are defined in the IEEE 802.1Q, 802.1ad and 802.1p specifications. Ethernet V irtual Connections can be configured with Provider VLAN to support E-Line and E-LAN connections on Metro Ethernet Networks.

Access to the management control can be restricted with the Port VLAN and Tag VLAN features, helping to prevent Denial-Of-Service (DoS) and unauthorized management access.

Other advanced features include:

• Real-time MIB statistics reporting (38 variables) • 802.3ah OAM and Extensions

• Port Access Control • cNode Level 1 Agent

• SNMPv1, SNMPv2c, SNMPv3 Refer to the appropriate sections for configuration information.

2.0 PORT STRUCTURE

2.1 OVERVIEW

The front panel of the 2GXM provides access to the management (serial console) and fiber ports. The fiber ports are SFP supporting 1000BASE-FX transceivers. The plug-in module features two additional Ethernet ports for connectivity via the chassis backplane.

2.1.1 Management Port

PI SA

The 2GXM features a Serial RS-232 Console Port (aka Craft Interface) which can be connected to a computer for initial setup and configuration. The Serial Console Port is accessed through the mini DIN-6 female DCE interface. Connect the interface to a computer’s DB-9 serial port using the mini DIN-6 male to DB-9 female cable adapter (Part # 8082-0), which is included with the 2GXM.

An optional DB-9 male to female straight-through serial cable is available for extension (Part # 8081-3).

2.1.2 Fiber Ports

PI SA

The fiber interface supports the 1000BASE-X protocol. The fiber interface operates in auto-negotiation or manual mode and supports full duplex operation. The fiber port can be enabled or disabled via network management. A port disabled with the Port Access Control feature will still connect and allow 802.3ah OAM or IP-less (secure) OAM communication, but blocks normal data traffic.

2.1.3 Backplane Ethernet Ports

The plug-in module supports two additional 10/100Mbps Ethernet Backplane Ports. The Backplane Ports A and B allow Ethernet data connectivity between adjacent modules in an iConverter chassis. The two backplane ports can be disabled or enabled via a DIP-switch or network management.

The iConverter 19-Module, 5-Module, 2-Module and 1-Module Redundant Chassis backplanes provide ethernet data connectivity between adjacent slots or ports. The A and B backplane ports connect the slots as illustrated.

3.2.2.1 SW1 - Backplane Port A Enabled “A-DS/A-EN”

When the DIP-switch is in the Left “A-DS” position (factory default), Backplane Port A of the 2GXM is isolated from the chassis Backplane. When the DIP-switch is in the Right “A-EN” position, Backplane Port A of the 2GXM is enabled. This port allows Ethernet Backplane connectivity to an adjacent module via the chassis Backplane Port A. See the backplane illustrations in Section 2.1.3.

3.2.2.2 SW2 - Backplane Port B Enabled “B-DS/B-EN”

When the DIP-switch is in the Left “B-DS” position (factory default), Backplane Port B is isolated from the chassis Backplane. When the DIP-switch is in the Right “B-EN” position, Backplane Port B is enabled. This port allows Ethernet Backplane connectivity to an adjacent module via the chassis Backplane Port B. See the backplane illustrations in Section 2.1.3.

Page 7

3.2.2.3 SW3 - Pause Disable/Enable “Off/On”

When the Pause enable/disable DIP-switch is in the Left “Off” position (factory default), Port 2 of the 2GXM does not send, receive and/or react to Pause frames during network congestion. Setting this DIPswitch to the Right “On” position enables Port 2 of the 2GXM to send, receive and/or react to Pause frames to/from its link partner. This enables the 2GXM to stop transmitting traffic to its link partner and store incoming frames from the other port in the internal buffer until the congestion clears. If the internal buffer of the 2GXM becomes congested, it will transmit a Pause frame to its link partner.

NOTE: When Port 1 operates in Auto-Negotiation mode, the port advertises for Pause. When the Fiber optic ports (Port 1 and Port 2) operate in Manual mode, Pause is disabled.

3.2.2.4 SW4 - Master/Slave Auto-Select and Slave-Only “M/SL / SL

When multiple management modules such as the iConverter Network Management Module (NMM) and the 2GXM (or multiple self-managed modules such as 2GXM) are installed in the same chassis, only one management module can act as the chassis master. The master management module has the ability to make changes to the settings of the other modules in the chassis, while the slave management modules cannot make the changes. If an NMM is installed in the chassis, the NMM will always be the master, otherwise the lowest slot number with a management module installed will become chassis master.

When this DIP-switch is in the Left “M/SL” position (factory default), the assignment of mastership is automatically negotiated by the installed management modules. T o designate a specific management module as the master when no NMM is installed in the chassis, set the DIP-switch on the master module to the Left “M/SL” position, and set the other installed management modules’ DIP-switches to the Right “SL” position to enable Slave-Only mode.

Only the chassis master can change configuration settings of other modules.

3.2.2.5 SW3, SW5, SW6, SW7, SW8 - Reserved

These DIP-switches are for factory use only and must always remain in the LEFT position (factory default).

NOTE: DIP-switches marked Reserved must be kept in the Left (factory default) position.

3.3 INST ALLING PLUG-IN MODULES AND CONNECTING CABLES

a. Carefully slide the module into an open slot in the chassis. Align the module with the installation

guides and ensure that the module is firmly seated against the backplane. Secure the module by fastening the front panel thumbscrew (push in and turn clockwise to tighten) to the chassis front. Verify the “Pwr” LED is ON (indicating the chassis is powered).

a. The 2GXM standalone Network Interface Device (NID) is available in tabletop and wall-mounting

models. For wall-mounting, attach the NID to a wall, backboard or other flat surfaces. For tabletop installations, place the unit on a flat level surface. Attach the rubber feet to the bottom of the NID to prevent the unit from sliding. Make sure the unit is placed in a safe, dry and secure location.

To power the unit using the AC/DC adapter, connect the AC/DC adapter to the AC outlet. Then connect the barrel plug at the end of the wire on the AC/DC adapter to the 2.5mm DC barrel connector (center-positive) on the unit. Confirm that the unit has powered up properly by checking the power status LED located on the front of the unit.

To power the unit using a DC power source, prepare a power cable using a two-conductor insulated wire (not supplied) with a 14 AWG gauge minimum. Cut the power cable to the length required. Strip approximately 3/8 of an inch of insulation from the power cable wires. Connect the power cables to the 2GXM standalone unit by fastening the stripped ends to the DC power connector.

Connect the power wires to the DC power source. The Power LED should indicate the presence of power.

WARNING: Note the wire colors used in making the positive and negative connections. Use the

same color assignment for the connection at the DC power source.

NOTE: If mounting with a safety ground attachment, use the safety ground screw at the r ear of

the unit.

PI SA

b. Insert the SFP Fiber transceivers into the Port 1 and Port 2 SFP receptacles on the 2GXM.

NOTE: The release latch of the SFP Fiber transceiver must be in the closed (up) position before

insertion.

c. Connect the appropriate multimode or single-mode fiber cable to the fiber port of the installed module.

It is important to ensure that the transmit (Tx) is attached to the receive side of the device at the other end and the receive (Rx) is attached to the transmit side. When using single-fiber (SF) media converter models, the Tx wavelength on one end has to match the Rx wavelength on the other. Based on this guideline, single fiber SFP fiber transceiver models must be used in pairs, such as the 7214-1 matched with the 7215-1.

NOTE: In order to support Remote OAM Management Mode, Port 1 of the 2GXM must be connected to the Port 1 on the 2GXM or link partner.

3.4 CONFIGURE THE MODULE VIA COMMAND LINE INTERFACE

PI SA

To configure, attach the 2GXM to a DB-9 serial (RS-232) equipped computer with terminal emulation software such as HyperT erminal. The 2GXM Serial Console Port (DCE) is a mini DIN-6 female connector which can be changed to a DB-9 connector with the included adapter (Part #8082-0). Attach the ends of a serial cable to the serial port of the PC and the Serial Console Port of the 2GXM. This is a standard asynchronous serial interface. The pin-outs are illustrated below.
