FCC Regulations  
This equipment has been tested and found to comply with the limits for a class A digital device, pursuant  
to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful  
interference when the equipment is operated in a commercial environment. This equipment generates,  
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the  
instruction manual, may cause harmful interference to radio communications. Operation of this  
equipment in a residential area is likely to cause harmful interference, in which case the user will be  
required to correct the interference at the user’s own expense.

Media Converter Port in Full-Duplex Network  
CABLE SPECIFICATIONS (continued)  
In a full-duplex network, maximum cable lengths are determined by the  
cables used. See page 10 for cable specifications.  
COPPER CABLE  
NOTE: The 512-Bit Rule described below does NOT apply in a full-duplex  
network.  
Each RJ-45 connector requires 2 pairs of Category 5 rated cable.  
The 50-pin Telco connector requires 24 pairs of Category 5 rated  
cable.  
Media Converter Port in Half-Duplex Network  
The 512-Bit Rule applies separately to each collision domain.  
USING THE 512-BIT RULE  
Either shielded twisted-pair (STP) or unshielded twisted-pair (UTP) can  
be used. DO NOT USE FLAT OR SILVER SATIN WIRE.  
CATEGORY 5:  
In a half-duplex network, maximum cable lengths are determined by the  
round trip delay limitations of each Fast Ethernetcollision domain.  
(Switches and routers divide the network into separate Ethernet™  
collision domains.) The 512-Bit Rule determines maximum distances by  
calculating the collision domain round-trip delay in bit-times.

To calculate a collision domain round-trip delay in bit-times, find the  
longest path between any two

50  
terminal devices in the collision  
domain. Calculate the round  
trip delay by multiplying the  
length of the cable (in meters)  
by the delay per meter (in bit-  
times (BT)), then take the sum of  
all cable delays plus station  
(DTE), repeater, and multi-port  
media converter port delays. If

media converter power receptacle.  
3. Plug male outlet end of power cord into correct voltage, properly  
grounded, AC rack or wall power source.  
4. Verify that multi-port media converter is powered by observing  
illuminated power and status LED(s).  
 
Using LinkAlert™  
OPERATION  
The E-TX-FX-xx00 series multi-port media converter LinkAlertfeature allows  
each media converter port to pass 100BASE-TX-side link faults over the port link  
to the 100BASE-FX side and to pass 100BASE-FX-side link faults over the port  
link to the 100BASE-TX side.  
Use the status LEDs to monitor multi-port media converter operation in the  
network.  
NOTE: Each 100BASE-TX/ 100BASE-FX media converter port is identified by  
a number located just above the fiber connector(s) for that 100BASE-TX  
/100BASE-FX port connection. The LEDs that apply to each 100BASE-TX or  
100BASE-FX port connector(s) are located, when facing the multi-port media  
converter, at the left of the connector(s) for that 100BASE-TX or 100BASE-FX  
port connection.  
If the port does not detect a good link on the 100BASE-TX side, the port disables  
all transmission (including active-idle) on the 100BASE-FX side.
