Table 2-1 : Standard RJ-45 Wiring Color Codes
Some cabling information for this wiring guide:
•
Only two pairs of wires are used in the 8-pin RJ-45 connector to carry Ethernet signals
•
Even though pins 4, 5, 7 and 8 are not used, it is mandatory they be present in the cable
•
10Base-T and 100Base-T use the same pins (a crossover cable made for one will also work
with the other)
•
Pairs may be solid colours and not have a stripe
• Category 5 cable must use Category 5 rated connectors
The maximum cable run between the router and the supporting hub is 300 feet (90 meters). The
maximum combined cable run between any two end points (e.g. Router and PC/laptop via network hub)
is 375 feet (205 meters).
Devices on the Ethernet network continually monitor the receive data path for activity as a means of
checking that the link is working correctly. When the network is idle, the devices also send a link test
signal to one another to verify link integrity. Each Ethernet connector on the rear panel is fitted with two
LEDs to monitor the Ethernet connection.
10/100: This amber LED is ON when a 100Base-TX link is last detected. The
LED is OFF when a 10Base-T link is last detected (the LINK LED is
ON). Upon power-up the LED is OFF as the last detected rate is not
known and therefore defaults to the 10Base-T state until rate
detection is completed.
LN/ACT: This dual-purpose green LED indicates that the EMX-FC has
established a valid linkage to its hub, and whether the EMX-FC is
sending or receiving data. This LED will be ON when the EMX-FC
has established a good link to its supporting hub. This gives you a
good indication that the segment is wired correctly. The LED will be
OFF if there is no valid connection.
