A.2 FRM220-10/100iS-2 Dual Channel In-band managed 10/100 Fiber Media Converter
The FRM-10/100iS-2 (in-band converter) is a Dual Channel (2 converters in 1 card) 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-10/100iS-2 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).
Features
• Dual Converter on a single card (2 independent channels)
• Supports Loop Back Test
• Auto-Cross over for MDI/MDIX in TP port
• Supports far end fault (FEF) function via OAM
• Auto-Negotiation or Manual mode in TP port
• Supports link fault pass through (LFP) function
• Bandwidth control (32K or 512Kbps x N)
• Forward 2046 bytes (max.) packets in switch mode
• Forward 9K jumbo packets in converter mode
• Supports forwarding mode option
• Store and forward (switch) mode, Convert mode (small latency)
• Supports local or remote In-band management (Monitor and
Configure status) by the SNMP manager in FRM220
• Supports remote CPE power fail detection (Dying gasp)
• Provides Auto Laser Shutdown (ALS) function
• Supports Fiber Hardware Reset (FHR) function
• Provides fiber transceiver information for management
• Supports On-Line In-band F/W upgrade (local or remote) by the
• SNMP manager in FRM220

Management
The 10/100iS-2 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 two separate MC run with default parameters. The default parameters are: switch mode,
auto-negotiation, LFP disabled, ALS (Auto Laser Shutdown) disabled, and no bandwidth limit. When a fully
populated CH20 (with 19 10/100iS-2) is deployed, a total of 38 loops are available from the 2U FRM220-CH20.
Due to dimension limitations, the 10/100iS-2 is only available for SFP based fiber optics.
The management features for this card are identical to the 10/100i except that all functions are doubled on the dual
independent channel card.
10/100iS-2 is a dual channel media
converter that must be placed in
FRM220-CH20 for management.
It utilizes SFP for fiber connection
and two 10/100 Ethernet electrical
ports.
