or power strip. Each converter features a full set of LEDs that convey essential diagnostic and status information. See Section 4.1, LED Indicators, for specific LED function information. ProMedia-100 media converters are designed to provide low-temperature operation over an extended period to make them some of the most reliable in the industry.
3.0 INSTALLATION This section describes the installation of the ProMedia-100 media converters, including location, segment distance calculation and media connection. 3.1 Locating the Media Converter Unit The compact and lightweight design of the ProMedia-100 media converter allows it to be easily installed in most any location.
full-duplex media (15,000 m) [57/15,000 x 100% = 57%]. The length of twisted pair Segment Y is 12m (40 ft). This is 12% of the maximum allowable distance for 100BASE-TX full-duplex twisted-pair media (100 m) [12/100 x 100% = 12%]. The total of the two percentages (57% + 12%) is 69%, which is allowable. 3.2.2 Segment Distances, Half duplex Fast Ethernet shared bandwidth devices operate with multiple nodes in a traffic domain. When a node attempts to send a packet, it may hit another packet passing by, i.e.

It is obvious that using twisted pair wiring to connect the hubs would enable the interconnect length to be the 100 meters maximum for twisted pair media, and this would still leave about a hundred BTs as a safety margin. In other words, use of ProMedia-100s and fiber in this case did not gain allowable maximum cable distance vs. TP cable without the ProMedia-100s. Consider a more typical use of ProMedia-100s in a shared Fast Ethernet segment.
4. Connect the Receive (RX) port (dark colored post) on the ProMedia-100 to the Transmit (TX) port of the remote device. Use the non-color coded fiber strand for this. 5. The LINK LED corresponding to the fiber port, on the front of the product, will illuminate when a proper connection has been established at both ends (and when power is ON in the units at each end). If LINK is not lit after cable connection, the normal cause is improper cable polarity.
plug. Both types include a lightweight DC power cord to the applicable power jack on the media converter unit. 4.2 Front Panel LEDs Description LED PWR Illuminates GREEN to indicate the unit is receiving DC power. LINK (RJ45 port) Illuminates GREEN, to indicate proper connectivity on the 100BASE-TX network segment. LINK will turn off in the event connectivity is lost between the ends of the twisted pair segment or a loss of power occurs in the unit or remote device.
