Introduction
The MMC10G Series Mini Media Converters extend the distance of your
network by interconnecting LAN devices that are physically separated by
large distances.
The MMC10G Series Mini Media Converters include the following models:
MMC10GSP/SP
MMC10GT/SP
The MMC10GSP/SP is a fiber mode converter, and can be used for fiber
extension.
The MMC10GT/SP is a copper-to-fiber converter, which can be used in
Telecom or Enterprise applications where 10 Gigabit media conversion
and fiber extension is required.
Note
The MMC10G Series converters can support 1Gbps and 10Gbps
speeds, but as a layer 1 device cannot perform speed translation, so
both endpoints must be matched.

data sheet.
MMC10G Series Mini Media Converter Installation Guide
21
Twisted-Pair Port Here are the basic features of the twisted-pair (copper) port on the
MMC10GT/SP:
1Gbps or 10Gbps
IEEE 802.3u Auto-Negotiation compliant
Auto MDI/MDI-X
100 meters (328 feet) maximum operating distance
RJ45 connector
The twisted-pair port features an eight-pin RJ45 connector that uses all
eight pins at 1Gbps or 10Gbps. For the port pinouts, see “RJ45 Connector
and Port Pinouts” on page 69.
Note
For twisted-pair port cabling specifications, refer to “Cabling
Guidelines” on page 60.
Auto-Negotiation
or Full-Duplex
The MMC10GT/SP Media Converter supports Auto-Negotiation at 1Gbps
or 10Gbps. The copper port will only link at the speed of the installed SFP+
module. For example, if a 10G SFP+ module is installed, the copper port
can only link at 10G.
Auto MDI/
MDI-X
The 10Gbps RJ45 twisted-pair port on MMC10GT/SP can have one of two
possible wiring configurations: MDI or MDI-X.
The media converter features Auto MDI/MDI-X. The twisted-pair port
automatically determines the configuration of the port on the device to
which it is connected and then configures itself appropriately.
This feature allows you to use a straight-through cable when connecting
any type of device to the media converter, regardless of the wiring
configuration of the port on the device.
Loopback Tests Loopback tests are used to test the fiber optic network connection. In
loopback mode, the copper port is disabled and the fiber port is set to loop
all packets back to the sender, or generate packets, depending on the DIP
switch setting. A linked switch port can transmit test packets over the fiber
optic cable, which are then looped back by the connected MMC10G. As it
receives its original test packets, it checks for lost packets and packets
with errors, and displays the results in statistic counters. Figure 5 on page
22 shows a successful test, using an Allied Telesis switch as the link
partner.
Chapter 1: Overview
22
Figure 5. Loopback Test for MMC10GT/SP
A successful test verifies that the number of packets received equals the
number of packets sent. If the numbers do not match, try restarting the
media converter, making sure that the cables are connected properly or
replacing the fiber cable.
MMC10G Series Mini Media Converter Installation Guide
23
Note
Loopback tests only work for fiber optic ports, you cannot test a
copper port. Additionally, the fiber cable connectivity can only be
tested using the SFP+ 10Gbps transmitter. It cannot be tested with
SFP 1Gbps transmitter.
Note
Two SFP+ modules must be installed prior to enabling Loopback
Mode, or loopback will not function properly.
To use Loopback Mode, set SW1 to OFF and SW2 to ON. For more
information about DIP switches and how to set them, refer to “DIP
Switches” on page 26.
Caution
Loopback tests are disruptive to network operations. The media
converters do not forward network traffic during the test. Some
network traffic may be lost.

LED Modes
The ports have LEDs that display link status and traffic activity. The LEDs
have three modes:
Regular mode
Smart MissingLink mode
MissingLink mode
Normal Mode The Link/Activity LEDs on the media converter DIP switch set to the
normal mode (i.e., SML and Loopback Mode are not switched on) display
the status of the links on the ports to network devices. For instance, the
LEDs are solid green when ports have established links to network
devices, or flashing green when they are actively transmitting or receiving
network traffic. Conversely, the LEDs are off on ports that are not
connected to network devices or have not established links to devices.
The normal mode is typically used when the network devices connected to
a media converter cannot take advantage of the Smart MissingLink mode,
or when you want to use the Link LEDs to troubleshoot a link problem.
This mode is also useful after you have installed the media converter
modules and want to verify whether the ports have successfully
established links with the local and remote network devices.
Smart
MissingLink™
(SML)
If one of the Ethernet connections to the media converter loses a link, the
SML feature allows you to determine which port still has a valid connection
and which port requires troubleshooting. The value to this type of network
monitoring and fault notification is that you can quickly determine which
media converter port has failed and troubleshoot the specific area where
the problem is occurring.
Note
SML only works with 10G connections.
When the media converter detects a loss of connection on one of the
ports, the port’s Link LED is turned OFF. At the same time, the media
converter causes the opposite port’s Link LED to blink while
simultaneously turning OFF that port’s Ethernet connection to its end
node. This occurs even though the properly operating port had a valid
connection before the failure occurred. The reason for this is so that its
end node is notified that the data path has been compromised, and
immediate action is required.
For example, if the network connection to the MMC10GT/SP Media
Converter’s twisted-pair port fails (as shown in Figure 14 on page 30), the
fiber Port 2 Link LED blinks slowly while the fiber port’s link is turned OFF.
MMC10G Series Mini Media Converter Installation Guide
29
The copper Port 1 Link LED is turned OFF, indicating a failed connection
on the twisted-pair port.
If the failure had started with the fiber-optic cabling (as shown in Figure 15
on page 30), then the copper Port 1 Link LED would blink slowly, and the
fiber Port 2 Link LED would turn OFF.
SML Example Scenarios in Normal Condition
Following are example scenarios with SML-enabled media converters.
Figure 11 shows Link LED behavior of end nodes and a media converter
with copper and fiber ports with SML enabled under normal condition.

be used to connect the two media converters together.

Guidelines to the
LED Modes
Here are the guidelines to using the LED modes:
Smart MissingLink mode is the default for MMC10GT/SP.
MissingLink mode is the default for MMC10GSP/SP.
The LED modes do not block or interfere with the flow of traffic
between the two ports during normal network operations.
Smart MissingLink and Regular modes are useful in identifying
ports that cannot establish links to network devices or have lost
links. In Smart MissingLink mode, if only one port has a link to a
network device, the LED for the port that lost link will be off, while
the LED for the port that had a valid link will blink once a second. In
contrast, if the media converter is set to Regular mode, and only
one port has a link to a network device, its Link LED will be on
while the Link LED on the port with no link will be off.
Note
The MMC10GT/SP cannot link in 1G mode unless both ports have
valid link partners
The Smart MissingLink mode can also be useful in situations
where both network devices connected to the ports can react to
the loss of a link by performing specific actions, such as sending
SNMP traps or seeking a redundant path.

Troubleshooting
This chapter contains information on how to troubleshoot the media
converter if a problem occurs.
Note
For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.
Problem 1: The PWR LED on the media converter is off.
Solutions: The unit is not receiving power. Try the following:
Verify that the power cord is securely connected to the power
source and to the DC connector on the back panel of the media
converter.
Verify that the power outlet has power by connecting another
device to it.
Try using another power adapter of the same type that came with
your media converter.
Verify that the voltage from the power source is within the required
levels for your region.
Problem 2: The SYS LED on the media converter is off.
Solution: An internal component on the unit is damaged or not working
properly. Try power cycling the unit. If power cycling does not clear the
fault, return the unit to Allied Telesis.
Problem 3: The SYS LED on the media converter is blinking slowly.
Solutions: The media converter may be in Loopback mode or an error is
present on the unit. Try power cycling the unit.
A transmit fault may be occurring on the SFP+ module. The media
converter will try to clear this error, but if the error persists, try the
following:
Remove and re-seat the SFP+ module.
Try a different SFP+ module.
Verify the SFP+ module is the correct type for your application.
Chapter 5: Troubleshooting
64
Problem 4: The twisted-pair Port 1 on the MMC10GT Media Converter is
connected to an end node, but the port’s copper Port 1 LINK LED is off.
Solutions: The port is unable to establish a link to an end node. Try the
following:
Verify that the end node connected to the twisted-pair port is
powered on and is operating properly.
Verify that the twisted-pair cable is securely connected to the port
on the media converter channel and to the port on the remote end-
node.
Verify an SFP module is installed and recognized by the media
converter (MMC10GT/SP).
Verify that the port is connected to the correct twisted-pair cable.
This is to eliminate the possibility that the port is connected to the
wrong end-node, such as a powered-off device.
Try connecting another end node to the twisted-pair port with a
different cable. If the twisted-pair port is able to establish a link,
then the problem is with the cable or the other end-node.
Verify that the twisted-pair cable does not exceed 100 meters
(328 feet).
Verify that the end node connected to the media converter is
operating at the same speed.
Verify that you are using the appropriate category of twisted-pair
cable:
– 1G: Cat 5e
– 10G: Verify the cable length is not too long for the
type of cabling used. See Table 7, “Twisted-Pair
Port Cabling Specifications” on page 43.
Note
A connection may require 5 to 10 seconds to establish a link.
Problem 5: The LINK LED for an SFP+ port is off.
Solutions: The fiber-optic port on the transceiver is unable to establish a
link to an end node. Try the following:
Verify that the end node connected to the fiber-optic port is
operating properly.
Verify that the fiber-optic cable is securely connected to the port on
the media converter and to the port on the remote end-node.
Verify that the end node connected to the media converter is
operating at the same speed.
Check that the SFP+ module is fully inserted in the port.
MMC10G Series Mini Media Converter Installation Guide
65
Verify that the operating specifications and wave lengths of the
fiber-optic port on the SFP+ transceiver and the remote end-node
are compatible.
Verify that the correct type of fiber-optic cabling is being used.
Verify that the port is connected to the correct fiber-optic cable.
This is to eliminate the possibility that the port is connected to the
wrong remote end-node, such as a powered-off device.
Try connecting another end node to the fiber-optic port using a
different cable. If the port is able to establish a link, then the
problem is with the cable or with the other end node.
Verify that the fiber TX strand is connected to link partner's RX, and
vice versa.
If the remote end node is a management device, use its
management firmware to determine whether its port is enabled.
Test the attenuation on the fiber-optic cable with a fiber-optic tester
to determine whether the optical signal is too weak (sensitivity) or
too strong (maximum input power).
Problem 6: Fiber speed LED is blinking and alternating between green
and amber (MMC10GT).
Solution: The media converter cannot detect the speed of the installed
SFP. The copper port is disabled in this scenario.
Problem 7: Network traffic is not being received at the end point.
Solution: Verify cabling by using loopback mode attached to a managed
switch port that can transmit test packets.
Problem 8: Loopback mode is not working.
Solution: Power unit off. Install (or re-seat) two 10G SFP+ modules.
Power unit on and check loopback.
