1.0 Introduction
Thank you for choosing the FRM220 Platform Fiber Media Converter Rack. If you would like to skip right to the
provisioning of the Network Management Controller, proceed to Chapter 2.
This manual is used to explain the configuration of the FRM220-NMC (Network Management Controller) and
operating procedures. This manual is divided into 4 Sections, the Introduction
, Provisioning, Web Based
Management and Trouble Shooting, plus the Appendices. The Appendices include the details for each card, pin
assignments of special cables and gives further information on options for placing the device in service.
The divisions of the manual are intended for use by personnel to answer questions in general areas. Planners
and potential purchasers may read the Introduction
to determine the suitability of the product to its intended use;
Installers should read the FRM220 Hardware Installation Manual
and the Cabling Specification Appendix in this
manual; Operating Personnel would use the Provisioning
and Web Based Management Chapters and Appendices
to become familiar with the various media converter cards and settings. Network Administrators should read the
chapters on Provisioning
, Web Based Management and Trouble Shooting to become familiar with the diagnostic
capabilities, network settings and management strategies for the SNMP managed chassis with NMC.
1.1 Brief Functional Description
The FRM220-CH20 is a 2U, 19(23)", 20 slot modular media converter rack. The FRM220-CH20 provides an
economic solution in high density Fiber Converter installations for FTTx, Metro LAN, or in enterprises, campus and
central offices. All critical components such as power modules, fans assemblies, management modules and
interface cards are hot swappable, allowing online field replacement. Additional features allow the FRM220-CH20
to detect the working or failing status either of power module or any fan assembly in the unit and activate relays
that can be used to control external alarm devices.
The FRM220-CH20 has a total of 20 slots in the front of the chassis. There are 19 slots available for installation
of FRM220 converter cards with 1 (one) slot reserved for the FRM220-NMC network management controller. The
FRM220-NMC or Network Management Controller is installed in the first reserved slot, for local and remote
management purposes. Each FRM220 card is an independent electrical to electrical, optical to electrical, or optical
to optical converter. When linked to a compatible FRM220 stand-alone "OAM" series FMC (Fiber Media Converter)
stand-alone converter, complete in-band management is supported. All settings of the line card and remote
connected stand-alone device may be managed through any of the available management interfaces.
A variety of cards are available that support multi-mode or single-mode fiber types and connections to LC, SC,
ST, FC or even the latest single fiber WDM (Wave Division Multiplexing) in ranges from 2Km to 120Km. Converter
cards include Fast Ethernet, Gigabit Ethernet, Asynchronous Serial (RS-485, RS-232 and RS-422), G.703 E1,
T1(DS1), Asynchronous and Synchronous Data (V.35, RS-530, X.21, RS-449, and RS-232), POTS over fiber, 2.7G
3R repeater, 10G 3R repeater, 4G 2R repeater, 4E1/T1 FOM and more as the product matures.
1.2 Installing the NMC
The front of the FRM220 contains the card slots. They are numbered 1 through 20, from left to right as viewed
from the front. The typical configuration requires one NMC (Network Management Controller) card in slot number 1
and in-band manageable cards in any other slot numbered 2 through 20.
