Safety Requirements
Caution!
To reduce risk of electrical shock and fire and to maintain proper operation,
ensure that the safety requirements stated hereunder are met!
Before Installing
Power Ensure that all power to the MC112FL is cut off. Specifically, disconnect the
MC112FL power cord from the power source (line/mains).
Inspection Ensure by visual inspection that no part of the MC112FL is damaged.
Covers The optical connectors of the MC112FL must be covered with dust caps at all
times until they are about to be connected.
Site Reserve one of the following sites for the MC112FL:
– 443 mm x 44 mm x 179 mm (19 in x 1U1x 7 in) space in a 19-inch rack
or
– Flat, stable, non-conductive, static-free surface (e.g., desktop or shelf).
Before Powering On
Temperature Operate the MC112FL only at a location where the ambient temperature is in
the range 0 to 40 oC (32 to 104 oF).
Humidity Operate MC112FL only at a location where the ambient humidity is non-
condensing and in the range 5 to 90 %.
Cooling Air Ensure that the air-flow around the MC112FL and through the air vents is not
obstructed. In addition, ensure that there is a clearance of at least 25 mm (1
inch) between the air vents and nearby objects.
Power Source Ensure that the power source (line/mains) can supply:
100 to 240 Vac, 0.8 A at 60/50 Hz
Power Cord The ac power cord of the MC112FL must have the following specification:
In the USA and Canada
UL approved and CSA certified flexible 3-conductor power cord having
individual conductor wire of gauge #18 AWG and length not exceeding 4.5 m
(15 ft). The power cord terminations should be NEMA Type 5-15P (3-prong,
one prong for earthing) at one end and an IEC appliance inlet coupler at the
other end.
Any of the following types of power cords are acceptable:
G, S, SE, SJ, SJE, SJO, SJOO, SJT, SJTOO, SO, SOO, SP-3, SPE-3, SPT-3,
ST, STO, STOO, SV, SVE, SVO, SVT, SVTO, SVTOO, W.
In all other countries

organization of the country. The power cord must be Type HAR (harmonized),
with individual conductor wire having cross-sectional area 0.75 sq. mm. The
power cord terminations should be a suitably rated earthing-type plug at one
end and an IEC appliance inlet coupler at the other end. Both of the power
cord terminations must carry the certification label of the cognizant safety
organization of the country.

MC112FL User Manual ML47766, Rev. 02 July 2007
Overview
Function
The MC112FL is a media converter that converts Ethernet/IEEE 802.3 10Base-T signals into
Ethernet/IEEE 802.3j 10Base-FL signals and vice versa in the opposite direction.
Using the MC112FL to convert an electrical interface of a device into a fiberoptic interface
provides the added benefits of fiberoptic cabling, such as, increased operating distance, EMI/RFI
immunity, protection against intrusion and eavesdropping, safety from electrical shock, etc.
Essentially, the MC112FL is 12 independent single-input/single-output media converters – all in
one compact package for cost-effectiveness and convenience. Accordingly, up to 12 pairs of
devices can be interconnected with the MC112FL, each pair retained in its own collision domain.
Features
Key features of the MC112FL are as follows:
• 12 pairs of electrical and fiberoptic ports.
• Plug-and-play
• Full-duplex operation mode
• Protective Link Integrity Notification (LIN2) mechanism.
• Front panel per-port diagnostic LEDs
• Universal (wide-range) internal power supply
• Rack mountable
Application
An MC112FL is used to interconnect up to 12 devices having Ethernet/IEEE 802.3 10Base-T
ports to as many devices having Ethernet/IEEE 802.3j 10Base-FL ports, as shown in Figure 1,
and to extend their operating range which can reach up to 2000 m (6561 ft).

side.
