About Media Converters
The modular Media Converter Series includes
modules that convert copper to single-mode,
multi-mode or single-strand fiber at Ethernet, Fast
Ethernet and Gigabit Ethernet speeds, and mod-
ules that convert copper to thin coax at Ethernet
speeds. Modules install in a variety of chassis.
N O T E
This manual will refer to
all types of modules as "Media
Conversion Modules" except where differences require indi-
catation.
Media Converter Chassis
Media Converter chassis provide power to the media conversion modules.
•1-P P ort (LE7401A-R2) chassis include one media conversion module slot.
•4-P P ort (LE7404A) chassis include four media conversion module slots.
•8-P P ort (LE7408A) chassis is a 1U high rackmountable that includes eight
media conversion module slots.
The 1, 4 and 8 slot chassis include a fixed 100/240 VAC power supply.
•12-P P ort chassis is rackmountable and includes 12 media conversion module
slots and either a 100/240 VAC (LE74012A) or -48 VDC (LE74012A-DC)
power supply. The 12-Slot chassis is 1U high and has the power on the rear
of the chassis with media conversion module slots on the front.
10Mbps Media Conversion Modules
10Mbps Media Conversion Modules provide a single conversion between
10Base-T twisted pair and either 10Base-FL fiber or 10Base-2 coax. Each module
requires one slot in a Media Converter chassis. The following versions are available:
LE740-TPSTM-R2
TP/FO-MM850-ST
LE740-TPSTM-SC-R2
TP/FO-MM850-SC
LE740-TPSTS20-R2
TP/FO-SM1310/PLUS-ST
LE740-TPSCS20-R2
TP/FO-SM1310/PLUS-SC
LE740-TPBNC
NOTE: All modules support half- and full-duplex except modules with BNC connectors are always HDX.

Black Box recommends connecting the twisted pair cable NOTE: The appropriate type of cable must be used for a link to be established. Refer to to a PC for this type of test. -
Page 6: About Linkloss And Fiberalert
The appropriate “LNK” (link) LED is lit to indicate this. The Black Box media converter also sends out link pulses from its copper and fiber transmitters, but normally has no way of knowing whether the cable to the other device is intact and the link pulses are reaching the other end. -
Page 7: Led Operation
When installing a redundant power supply module into a powered-on on the twisted pair segment of a conversion, TP/TX LinkLoss detects the fault chassis, Black Box recommends setting the ON/OFF switch on the module and passes this information to the fiber segment. If a media converter is not (if present) to OFF. -
Page 8: Auto-Negotiation
Since single-strand fiber products use optics that transmit and receive on two different wavelengths, you must deploy single-strand fiber products in pairs, or connect two compatible Black Box single-strand fiber products. For example, connect Compact Media Converter, TX/SSFX-SM1310-SC (which has 1310 xmt and 1550 rcv) to a...
