1.7 Line card options

The FRM220 is capable of supporting a variety of in-band managed or non-managed line card types which

may be mixed and matched in any slot of the rack. See below for a brief of the linecards at the time of this printing.

Please refer to the latest version of FRM220 NMC User Manual for details of all the line card options for the

FRM220.

1.7.1 FRM220-10/100i In-band managed 10/100 Fiber Media Converter

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.

Management

atency)

) by the

10/100i is a media converter that

must be placed in FRM220-CH20

for management.

It utilizes fixed transceiver for

100Base-FX fiber connection and

one 10/100 Ethernet electrical port.

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 parameter. 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.

This product includes the following models:

• FRM220-10/100i (1 electrical plus 1 Fixed transceiver media converter)

• FRM220-10/100iS (1 electrical plus 1 SFP media converter)
