1.0 Introduction
Thank you for choosing the FRM220A Ethernet Aggregate Fiber Media Converter Rack. If you would like to
skip right to the provisioning of the Gigabit Ethernet switch, proceed to Chapter 2.
This manual is used to explain the configuration of the FRM220A-GSW/SNMP (Gigabit Switch / SNMP
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
FRM220A 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 GSW/SNMP.
1.1 Brief Functional Description
The FRM220A-CH20 is a 2U, 19(23)", 20 slot modular media converter rack. The FRM220A-CH20 provides an
economic solution in high density Ethernet 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
FRM220A-CH20 to detect the working or failing status either of two redundant power modules or any fan assembly
in the unit and activate relays that can be used to control external alarm devices.
The FRM220A-CH20 has a total of 20 slots in the front of the chassis with all 20 slots available for installation
of FRM220A converter cards. The FRM220A-GSW/SNMP or Gigabit Switch Management Card is installed from
the rear of the chassis, for local and remote management purposes. Each FRM220A card is an independent optical
to electrical or optical to optical Ethernet converter. When linked to a compatible FRM220A 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.
1.2 Card Options
Currently only two series of cards are available for the FRM220A . These are the iMUX series of Inverse
Multiplexers that support 1, 5, 8, or 16 E1 bundled inverse multiplexers (Ethernet over E1) and the FRM220A-
1000EAS/X , a 4-port (two SFP and two UTP) gigabit Ethernet L2 switch card. A soon to be released Fast Ethernet
card, FRM220A-FSW301 , features 1 fiber (100Base-FX) port and 3 UTP (10/100M) ports. FRM220A cards all
feature Ethernet backplane connections that allow aggregation of L2 Ethernet traffic through the GSW/SNMP
Gigabit Switch.
