Introduction
The Lantronix M-MCR-01 is a 19” powered chassis for Lantronix Mini Media Converters. Note: the M-MCR-01 is
only intended for installation of supported Mini Media Converters designed and built by Lantronix.
The M-MCR-01 is a high-density powered 19” rack mountable chassis for Lantronix Mini Converters, the most
miniaturized converters in the industry. It offers a powered standard 19” chassis for Mini Converter installation and
power input in central office and other deployments, as an accessory to the Mini Converter series portfolio.
The M-MCR-01 features 18 slots for side-mounted Mini Converters, an internal AC power supply (included) to
provide 12 VDC output, and a powered backplane with barrel connectors. Lantronix’ M-MCR-01 provides space
and power in a rack-mountable chassis for eighteen (18) separate and independent Lantronix stand-alone Media
Converters, each with power requirements of 12 VDC.
Product Description
The M-MCR-01 Mini Media Converter Chassis is a 19” rack mountable powered chassis for the Mini family of
stand-alone media converters. Designed for Lantronix’ line of office grade, non-hardened, mini media converters,
this chassis is ideal for installations where multiple Minis are being deployed in the same location. The M-MCR-01
offers a simple, cost-effective way to securely mount up to 18 Mini Converters while requiring a single AC power
connection.
As networks grow, so does the need to interface between various types of cabling infrastructure, and the Mini
copper-to-fiber Media Converters offer a low cost, space saving option for making those connections between
disparate cable types. The M-MCR-01s is suitable for Enterprise and Government applications where multiple
points of fiber connectivity are required. The chassis can accept any combination of Lantronix layer 1 100Base
and 1000Base Mini Media Converters as well as the layer-2 10/100 and 10/100/1000 Mini media converters, all
with the barrel-type DC power input connector. Each M-MCR-01 slot has a fuse to keep one malfunctioning Mini
Converter from affecting the rest.
The M-MCR-01 occupies 1.5U of rack space, allowing two chassis to be mounted in 3 units of rack space,
efficiently using critical rack space in datacenters or wiring closets. The Mini Converters are hot-swappable and
directly connect to the chassis backplane to receive their power connection. Three lock-down bars can be raised
and lowered to allow additional Mini Converters to be installed in an active chassis. These bars are also used to
securely hold the Mini Converter in the chassis, even when the copper and fiber data cables are being inserted
and removed from the individual Mini Converters.

Installation
Table Top Installation
The M-MCR-01 is shipped with nine (9) black rubber feet for optional installation on a table or other flat, stable
surface. When installing on a table top, remove the rubber feet from the card and place them evenly spaced on
the bottom of the chassis. The M-MCR-01 must be installed in a well-ventilated area.
Rack Installation
The M-MCR-01 ships with four (4) attachment screws for installation in a standard rack.
Warning: Take care to mount the M-MCR-01 so that it will not fall. Failure to observe this warning could result in
an injury or damage to the equipment.
Caution: Follow the rack manufacturer’s recommendation for mounting the M-MCR-01 into the rack.
Caution: Ensure that proper airflow around the M-MCR-01 is maintained.
Safety Instructions for Rack Mount Installations
The instructions below (or similar) are intended for rackmount installation environments:
1. Elevated Operating Ambient: if installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may exceed room ambient. Install the equipment in an environment
compatible with the maximum ambient temperature (Tma) specified.
2. Reduced Air Flow: install the equipment in a rack so that the amount of air flow required for safe operation is
not compromised.
3. Mechanical Loading: Mount the equipment in the rack so that a hazardous condition does not occur due to
uneven mechanical loading (weight distribution/rack balance).
4. Circuit Overloading: consider the connection of the equipment to the supply circuit and the effect that
overloading of the circuits might have on overcurrent protection and supply wiring. Consider all equipment
nameplate ratings when addressing this concern.
5. Reliable Earthing: maintain reliable earthing of rack-mounted equipment; pay particular attention to supply
connections other than direct connections to the branch circuit (e.g., use of power strips).
Mount One M-MCR-01 into a Rack
The M-MCR-01 is 1-1/2 U high, and you can use 2 RU to rack-mount a single chassis, or use 3 RU to rack-mount
two M-MCR-01 chassis as follows:
1. Locate four (4) screws (provided) and optional clip-nuts (not provided) for each M-MCR-01 Media Converter
Rack.
2. Carefully align the M-MCR-01 at a level position between the rack mounting rails as shown on the next page.
3. Install two (2) screws through the right front bracket and two (2) screws through the left front bracket; use the
clip nuts to secure the M-MCR-01 to the rack.

Mount Two M-MCR-01s into a Rack
To mount two M-MCR-01 units in three RU of rack space:
1. Locate four (4) screws (provided) and optional clip-nuts (not provided) for each M-MCR-01 Media Converter
Rack.
2. Carefully align the M-MCR-01 at a level position between the rack mounting rails as shown below.
3. Install two (2) screws through the right front bracket and two (2) screws through the left front bracket.
Optionally, use the clip nuts to secure the M-MCR-01 to the rack.
Note: use the top holes / screws to mount the top unit and use the bottom holes / screws to mount the bottom
unit. The two mounted M-MCR-01 units should look like this:

Install Media Converters into the M-MCR-01
1. Position the media converter in the M-MCR-01 as shown below and then carefully slide it into the slot.
2. If desired, slide the captive panel down to secure the bank of six media converters (optional).
3. Tighten the lock-down bars (captive panel fastener) located directly above the bank of threee media converter
to secure it to the M-MCR-01.
Mount Power Supply to the M-MCR-01
The M-MCR-01 ships from the factory with the Power Supply attached to the M-MCR-01 chassis.

Connect Power to the M-MCR-01
Caution: Make sure that the M-MCR-01 will not overload the circuit used to supply power. See the
Technical Specifications section on page 9for current and power maximums.
Warning: Make sure that the M-MCR-01 is properly grounded. Failure to observe this warning could result
in an electrical shock.
1. Insert the male end of the power cord into the M-MCR-01 Input Power (PWR) Barrel Connector.
2. If desired, use the Cable Clamps to restrain the Power Cord (optional).
3. Insert the other end of the Power Cord into a live AC wall outlet.
4. Verify that the media converter front panel Power LED lights. The LEDs vary between mini media converter
models. A “generic” and a model-specific set of front panels are shown below. See the related media
converter user guide for LED details.
