Appendix A. FRM220 Cards Options
A.0 Introduction
The FRM220 In-Band Managed Media Converter Chassis is designed to accept a variety of optical to electrical
or optical to optical converter cards. As cards are added, this section will be updated with the relevant information
for the new cards. The management interface and all cards support software upgrading so that new cards and new
features may be added at any future date. Please refer to Chapters 2&3 for details on the upgrade method and
procedures for operating the
FRM220 NMC .
A.1 FRM220-10/100i In-band managed 10/100 Fiber Media Converter
A.1.1 General Information
The FRM-10/100i (in-band converter) is an In-band Managed (OAM) Fiber Ethernet media converter (MC) that
supports 10Base-T or 100Base-TX and converts to 100Base-FX (fiber). The UTP side supports auto-negotiation or
forced settings for speed and duplex by setting as well as auto-MDIX. When the FRM-10/100i is placed in the
FRM220 with NMC , the settings are controlled by the chassis management system. The remote FRM-10/100i
stand-alone may also be configured from the FRM220 through the in-band management features (OAM). An
optional console manageable single slot chassis, the CH01M, is also available with DB9F connector for stand-
alone serial console management.

A.1.2 Functional Details
Ethernet
The 10/100Base RJ-45 connector is located on the front panel of the line card. One RJ-45 connector is
provided for each interface converter. All connections are designed for auto MDI-X operation, requiring only a
straight connection to any device. A unique feature of the FRM220-10/100i converter is the use of a common PCB
card which may either be used as a standalone converter (FRM220-CH01 series) or placed in the FRM220-CH20
rack. Additionally, this same converter is available in a fixed (non-card type) converter with built-in power (the OFC-
10/100i).
Management
The 10/100i line card is managed by an on-card CPU when installed in the FRM220 CH20 chassis. There are
no DIP switches or manual settings. If the MC is placed stand-alone, without local or remote connection to FRM220
NMC management, the MC runs with default parameters. The default parameters are: switch mode, auto-
negotiation, LFP disabled, ALS (Auto Laser Shutdown) disabled, and no bandwidth limit. An optional console
manageable single slot chassis, the CH01M, is available with DB9F connector for stand-alone serial console
management. When using console port, both local and remote unit can be configured and monitored.
An additional model, 10/100iD model is available that adds a 4 pole DIP switch. However, this switch can only
support the settings of auto or forced mode on the Ethernet UTP.
