CHAPTER 8: Troubleshooting
When using UTP, what’s the best way to make sure that the system does not suffer from any
interference?
The Micro Extender is designed to withstand high levels of interference while
driving signals over UTP. To further reduce the potential for interference,
consider taking these actions:
a) Make sure that the Micro Extender’s Remote Unit, the remote monitor or
KVM switch, and the local CPU or KVM switch are all connected to the same
utility-power (mains) phase.
b) Make sure that the AC voltage across the utility-power (mains) grounds (at
both the local PC or switch and remote monitor or switch) is less than 2V.
c) Use a “clean earth” or “clean grounding” system (if your site has one
installed).
d)Route the interconnection cable away from generators, motors, compressors,
fluorescent lights, and other cables.
e) Try STP cable if you think noise could be a problem.
This interconnect cable is exactly like the cable I use on my LAN. Can I connect the Micro
Extender to my network?
Absolutely not. Regardless of the cable similarities, the data signals and voltages
used by the Micro Extender are totally different from those used by Ethernet and
other types of networks. Connecting the Micro Extender to a LAN hub, switch,
repeater, or other network device, or exposing it to the signal levels present on
network data lines, is a sure way to blow out the Micro Extender, and could
damage other devices attached to the Micro Extender as well.
