1.0 Introduction
Thank you for choosing the FRM220 Platform Fiber Media Converter Rack. If you would like to skip right to
the installation and provisioning of the Converter Chassis, proceed to Chapters 2 and 3.
This manual is used to explain the installation and operating procedures for the FRM220, and present its
capabilities and specifications. This manual is divided into 6 Sections, the Introduction, Installation, Operation,
Web Based Management and Trouble Shooting Chapters, plus the Appendices. The Appendices include the details
for each line 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 Installation Chapter and the Cabling Specification Appendix; Operating Personnel would
use the Operations and Web Based Management Chapters and Appendices to become familiar with the line cards
and settings. Network Administrators should read the chapters on Operation, Web Based Management and
Trouble Shooting to become familiar with the diagnostic capabilities, network settings and management strategies
for the SNMP managed chassis.
1.1 Functional Description
The FRM220 is a 2U high 19" Rack, 20 slot modular media converter center. The FRM220 provides an
economic solution in high density Fiber Converter installations in enterprises or central offices. All critical
components, Power, fans, management module and interface cards are hot swappable allowing online field
replacement. An additional feature allows the FRM220 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.
There are 19 slots available for installation of FRM Converter Cards in the FRM220 compact rack. An SNMP
Card is installed in the reserved slot, for local and remote management purposes. Each FRM Card is an
independent fiber to copper converter. When linked to a compatible FRM stand-alone or "I" 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 or will be available that support multi-mode or single-mode fiber types and connections to SC,
ST, FC or even the latest single fiber WDM (Wave Division Multiplexing) in ranges from 2Km to 120Km. Converter
cards will include Fast Ethernet, Gigabit Ethernet, Serial (RS-485, RS-232 and TTL), E1, T1, Datacom (V.35, RS-530,
X.21, RS-449, and RS-232) and more as the product matures.
The FRM220 optionally incorporates a redundant Power Module. The supply, depending on the model,
derives its power from either an AC power source (90 ~ 264VAC) and/or DC power source. Two available DC
power modules provide either 18-36VDC or 36-72VDC range. When two modules are installed, they provide for
power redundancy and are hot swappable even during the FRM Line Cards' transmissions. The FRM220 provides
all copper interface connections on the face of each FRM Line Card. The fiber interface connectors are also located
on the individual FRM Line Card's face, along with status indicator LEDs. The status LED indicators provide for
quick indications of both copper and fiber link statuses and in fault detection.
1.2 Chassis Front Description
The front of the FRM220 contains the line card slots. They are numbered 1 through 20, from left to right as
viewed from the front. The typical configuration is with one NMC (Network Management Controller) card in slot
number 1 and in-band manageable line cards in any other slot numbered 2 through 20.
