UTP Port LEDs
The UTP Port LEDs indicate Link, Activity, Error, and Partition status. If a
good link is established on any given port, the green LED will be continuously
lit, indicating a valid network connection between the network node and the
hub. When data is received, the LED will flash green. If the port is partitioned
or encounters an error, such as jabber, false carrier, misalignment, or invalid
packet, the LED will flash amber.
If an LED does not indicate a good link, check the following:
1. Make sure the power is turned on for both the PC and Fast EtheRx
Hub. The power LED should be lit.
2. Verify the network drivers have been loaded on the PC. Some adapters require
the drivers to be loaded to establish a proper link.
3. Make sure the cable is wired properly and connected on both ends.
4. If steps 1, 2, and 3 are correct, the cable may be defective or not wired
correctly. Replace the cable and try again. Please refer to Appendix A
for pin assignments and Appendix B for cabling guidelines.
Utilization LEDs
There are five utilization LEDs to display the amount of network traffic in five
percentage levels. The amount of data traffic is measured in frames per second
(FPS), then calculated into the following percentage forms: 1%, 12%, 25%,
50%, and 100%. The appropriate LED will light based on the network activity.
UTP and Uplink Ports
The UTP ports on the front panel, numbered 1 through 8 (KNE8TX/RS), 1
through 12 (KNE12TX/RS), or 1 through 24 (KNE24TX/RS), support
100BASE-TX connections. Since the crossover function is implemented on all
UTP MDI-X ports, a straight-through cable should be used to connect to a
workstation. The last UTP port on each model has two (2) RJ-45 connectors
for support of cabling in the crossover and straight-through configuration.
Only one of the two ports, MDI-X or MDI (
or ), may be used.
