About the McBasic-Gigabit

McBasic-Gigabit is a low-cost, preconfigured, IEEE 802.3 single-conversion media
converter that converts 1000Base-TX twisted pair to 1000Base-SX multi-mode or
1000Base-LX single-mode fiber. It is available with one RJ-45 connector for the
twisted pair port and an SC connector for the fiber port.

McBasic-Gigabit is also available in a single-strand fiber version which allows two
wavelengths to share one fiber strand — Full-Duplex data travels on different
wavelengths (1310 nm and 1550 nm) — doubling the capacity of fiber. The
McBasic-Gigabit includes one RJ-45 connector and one SC fiber connector.

NOTE

All McBasic-Gigabit units, including 1310 nm single-mode (TX/LX), 850 nm
multi-mode fiber (TX/SX) and single-strand versions (TX/SSLX), will be referred to
as McBasic-Gigabit throughout this installation guide except where differences
need to be indicated.

Installing a McBasic-Gigabit

To install McBasic-Gigabit, first make sure that the unit is placed on a suitable flat
surface. Attach the cables between the McBasic-Gigabit and each device that will
be interconnected and then plug the unit into a reliable, filtered power source.

INSTALLATION TIP

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 B&B Electronics single-strand fiber products. For example,
connect McBasic-Gigabit, TX/SSFX-SM1310-SC (which has 1310 xmt and 1550 rcv)
to a product which has 1550 xmt and 1310 rcv, e.g. McGigabit, TX/SSFX-SM1550­SC. The two connected products must also have the same speed and distance
capabilities (i.e. both are single-mode [20 km] or both are single/PLUS [40 km]).

AutoCross Feature for Twisted Pair Connection

All twisted pair ports on the Managed Media Converter Module 10/100-II include
AutoCross, a feature that automatically selects between a crossover workstation
and a straight-through connection depending on the connected device.

Configuration Instructions

McBasic-Gigabit has user-configurable features located on the PCB board. Please
refer to the board diagram and the table for available features.

To access the McBasic-Gigabit board for configuration, loosen the two screws on
the front of the unit. Slide the board out of the enclosure (faceplate is attached).
Configure, then slide the board back into the enclosure and tighten the screws.

Following is the McBasic-Gigabit PCB board used to configure the unit.

** WARNING **

Installing modules without understanding the effects of LinkLoss and FiberAlert
can cause functioning units to appear flawed or even non functional.

Link Integrity

During normal operation, link integrity pulses are transmitted by all point-to­point Ethernet devices. When an B&B Electronics media converter receives valid
link pulses, it knows that the device to which it is connected is up and sending
pulses, and that the copper or fiber cable coming from that device is intact. The
appropriate “LNK” (link) LED is lit to indicate this.

The B&B Electronics 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. The
combination of FiberAlert and LinkLoss allows this information to be obtained,
even when physical access to a remote device (and its link integrity LED) is not
available.

LinkLoss, FiberAlert and Link Fault Pass-Through

McBasic-Gigabit includes the troubleshooting features FiberAlert, TXLL, FXLL and
LFPT that help locate silent failures on a network. Before attempting to install the
module(s), understand how these features work and react to specific network
configurations.

FX LinkLoss (FXLL)

FX LinkLoss is a troubleshooting feature. When a fault occurs on the fiber
segment of a conversation, FX LinkLoss detects the fault and passes this
information to the twisted pair segment. If a media converter is not receiving a
fiber link, FX LinkLoss disables the transmitter on the media converter’s twisted
pair port. This results in a loss of link on the device connected to the twisted pair
port.

TX LinkLoss (TXLL)

TX LinkLoss is a troubleshooting feature. When a fault occurs on the twisted pair
segment of a conversion, TX LinkLoss detects the fault and passes this
