RJ-45 Ports (Auto MDI/MDIX)
8 auto-sensing ports of 10Base-T, 100Base-TX connections. [In general, MDI means
connecting to another Hub or Switch while MDIX means connecting to a workstation
or PC. Therefore, Auto MDI/MDIX means that you can connect to another Switch or
workstation without changing pin-to-pin or crossover cabling.]
DC Power Connector
Plug the female connector into the switch and male connector into a power outlet.
Supports input voltages 5VDC at 1000 mA.
Troubleshooting
The Switch can be easily monitored through panel indicators to assist in identifying
problems. This section describes common problems you may encounter and possible
solutions.
Power
If the power indicator does not light when the power cord is plugged in, you may
have a problem with the power outlet or cord. However, if the power LED goes off
after running for a while, check for loose power connections, power losses or surges
at the power outlet. Turn off power, wait 30 seconds and turn power on again. If
problem is still not resolved call for dealer's assistance
Diagnosing LED Indicators
If link indicator does not light after making a connection, check whether network
interface (e.g., a network adapter card on the attached device), network cable, or
switch port is defective. Be sure the cable is plugged into both the switch and
corresponding device. Verify the proper cable type is used and its length does not
exceed specified limits.
Cabling
Verify that the cabling type is correct. Make sure all cable connectors are securely
seated in the required ports. Use only standard Unshielded Twisted-Pair (UTP),
Category 3, 4, 5, or 5e cables. Use only Category 5 or 5e when connecting with Fast
Ethernet. Make certain the maximum distance between the Switch and what it's
connected to is 100 meters or less.
