•If using a high powered device (which is designed for long distance installations) for a short distance installation, the fiber transmitters may overdrive the receivers and cause data loss. If this is the case, you may need to add an optical attenuator to your connection.

Please contact Black Box for more information.

Fiber optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules.

1)Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier; low-quality components can cause many hard-to- diagnose problems in an installation.

2)Dust caps are installed by the manufacturer to ensure factory-clean optical devices. These protective caps should not be removed until the moment of connecting the fiber cable to the device. Assure that the fiber is properly terminated, polished and free of any dust or dirt and that the location is as free from dust and dirt as possible.

WARNING! Integrated circuits and fiber optic components are extremely susceptible to electro-static discharge damage. Do not handle these components directly unless you are a qualified service technician and use tools and techniques that conform to accepted industry practices.

3)Store spare caps in a dust-free environment such as a sealed plastic bag or box so that when reinstalled they do not introduce any contamination to the optics.

•In Force 100 mode, the media converter converts 100Base-TX to 100Base-SX multi-mode or 100Base-FX single-mode fiber; 10 Mbps signals are not accepted.

There is no auto-negotiation in Force-100 mode.

To enable Force-100mode, set switch S7 to the ON position, with switches S6 and S8 in the OFF position.

When connecting two 10/100 Autosensing Media Converters between two end stations (devices such as switches, hubs and repeaters), all devices in the media conversion should ideally support, and be utilizing, Auto-Negotiation functionality. While it is possible to have auto-negotiating devices on one side of the media conversion and fixed (non-auto-negotiating) devices on the other, link LEDs will react differently depending on where a link fault occurs. Therefore, Black Box recommends:

A)Configuring every device in the media conversion for Auto-Negotiation.

For installations where Auto-Negotiationis NOT possible from one end of the media conversion to the other:

B)Manually configure all devices for 10 Mbps or 100 Mbps connections.

10/100 Autosensing Media Converter include two advanced troubleshooting features, Transparency and Link Fault Detection (LFD), to help you locate “silent failures” on your network.

T R A N S P A R E N C Y F E A T U R E

Transparency is only available when using Auto-Negotiationmode; it is not available in either of the two Force modes. When the 10/100 Autosensing Media Converter is auto-negotiating, Transparency treats the connection between the two end devices as if there were no media converters installed. For example, in a typical application where two media converters are installed between two copper-based switches, the twisted pair cables as well as the fiber cable are seen as “one” entity. Therefore, if a fault occurs on any segment between the two end devices, link LEDs on the end devices will go out.

As stated, Transparency is available when the 10/100 Autosensing Media Converter is operating in Auto-Negotiation mode, therefore S6 (AN/PNP) must be ON and S5 (LFD), S7 (Force) and S8 (10/100) must be OFF.
