CANADA RADIO FREQUENCY INTERFERENCE STATEMENTS  
Class B Digital Device. This equipment has been tested and found to comply with  
the limits for a Class B computing device pursuant to Part 15 of the FCC Rules.  
These limits are designed to provide reasonable protection against harmful interfer-  
ence in a residential installation. However, there is no guarantee that interference  
will not occur in a particular installation. This equipment generates, uses, and can  
radiate radio frequency energy, and, if not installed and used in accordance with  
the instructions, may cause harmful interference to radio communications. If this  
equipment does cause harmful interference to radio or telephone reception, which  
can be determined by turning the equipment off and on, the user is encouraged to  
try to correct the interference by one of the following measures:  
• Reorient or relocate the receiving antenna.  
• Increase the separation between the equipment and receiver.  
• Connect the equipment into an outlet on a circuit different from that to which  
the receiver is connected.  
• Consult an experienced radio/TV technician for help.  
Caution:  
Changes or modifications not expressly approved by the party responsible for com-  
pliance could void the user’s authority to operate the equipment.  
To meet FCC requirements, shielded cables and power cords are required to con-  
nect this device to a personal computer or other Class B certified device.  
This digital apparatus does not exceed the Class B limits for radio noise emission  
from digital apparatus set out in the Radio Interference Regulation of Industry  
Canada.

Chapter 2: Overview  
2. Overview  
2.1 Introduction  
The Pure Networking LGC200A, LGC201A and LGC202A are Gigabit Media  
Converters. The SFP port of the LGC200A supports hot-swappable, Gigabit SFP  
modules. The LGC201A has a dual SC multimode fiber connector, and the LGC202A  
has a dual SC single-mode fiber connector.  
Use the media converters to join a 1000BASE-TX segment to a 1000BASE-SX or  
1000BASE-LX segment on your network, or use them in pairs to extend the  
328-feet (100-m) distance limitation of copper-based Ethernet.  
Three converter models are available:  
• LGC200A: This SFP module media converter transmits/receives data based on the  
SFP module that is installed.  
• LGC201A: This fiber SC media converter transmits/receives data by 850-nm  
short-wave laser over multimode fiber.  
• LGC202A: This fiber SC media converter transmits/receives data by 1310-nm  
short-wave laser over single-mode fiber.  
2.2 Features  
• Complies with 802.3ab and 802.3z standards.  
• Provides (1) SC/LC connector or (1) SFP module slot and (1) RJ-45 connector.  
• Both TX and FX ports work at 1000 Mbps in full-duplex mode.  
• Supports Auto MDI/MDI-X for the TX port.  
• Extends fiber distance up to 0.55 kilometers for multimode fiber and 15 kilometers  
for single-mode fiber.  
• Easy-to-view LED indicators provide status to easily monitor network activity.  
• Uses a 9-VDC, 600 mA external power supply (included).

NOTE: LGC200A could be connected to LGC201A or LGC202A; however, the SFP  
module in the LGC200A must use the same mode and wavelength as the  
opposite end. The fiber connectors depend on the type of SFP installed. See

4.2 Installation Procedure  
Use a fiber cable to connect two converters and extend a copper link or to connect  
a 1000BASE-FX segment to a 1000BASE-X segment on your network.  
1. Connect a converter to a 1000BASE-TX device (hub or switch).  
• Make sure that the CAT5 twisted pair cable between the 1000BASE-TX device  
and the converter is less than 328 feet (100) meters long.  
• Connect one end of the CAT5 twisted pair cable to the RJ-45 jack on the convert-  
er and the other end of the cable to the RJ-45 jack on the 1000BASE-TX device.  
2. Connect two converters or a converter and a 1000BASE-FX device.  
• Use an SC fiber cable to connect the two converters’ SC connector or the SC  
connector of a converter and a 1000BASE-FX device.  
3. Turn on the power.  
4.3 Install the Media Converter into the LHC200A-RACK  
1. Take out the two screws located on the top of the chassis and use them to install  
the retainer as shown in Figure 4-5.

Figure 4-5. Install the retainer.  
2. Turn off the switch power and take off the front guard that’s on the chassis.  
3. Preconfigure the media converter, then insert the media converter into the open  
slot of the chassis.  
4. Use the locking knob to lock the media converter tightly in the chassis.

5. Turn on the power switch and you will see the media converter’s Power LED light.  
Then you can operate it in the same way as a standalone Pure Networking Media  
Converter.

5.1 LEDs on the Media Converters  
The converters have real-time LED indicators that can provide real-time status  
reports. Just look at the LEDs to deterimine the link status. Figure 5-1 shows the  
LEDs, and Table 5-1 describes their functions.

mode. When connected to other products, such as switches, set the converter to  
auto-negotiation mode.

Chapter 6: Troubleshooting  
6. Troubleshooting  
6.1 Contacting Black Box  
If you determine that your Pure Networking Gigabit Media Converter is  
malfunctioning, do not attempt to alter or repair the unit. It contains no  
user-serviceable parts. Contact Black Box Technical Support at 724-746-5500  
Before you do, make a record of the history of the problem. We will be able to  
provide more efficient and accurate assistance if you have a complete description,  
including:  
• the nature and duration of the problem.  
• when the problem occurs.  
• the components involved in the problem.  
• any particular application that, when used, appears to create the problem or make  
it worse.  
6.2 Shipping and Packaging  
If you need to transport or ship your Pure Networking Gigabit Media Converter:  
• Package it carefully. We recommend that you use the original container.  
• If you are returning the unit, make sure you include everything you received with  
it. Before you ship for return or repair, contact Black Box to get a Return  
Authorization (RA) number.
