UNICOM Electric 5 Troubleshooting, Product Specifications, Introduction, Key Features

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.

■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.

Introduction

The 5 Port Micro-Switch/5(Auto MDI/MDIX) is a palm-sized Fast Ethernet switch that provides wire-speed, a Fast Ethernet switching function which allows high-performance, low-cost connections to Full-duplex, Half-duplex, 10Mbps and 100Mbps Ethernet networks. This Switch provides five auto- sensing 10/100Mbps Ethernet RJ-45 ports which automatically detect the speed of the devices that you plug into them. This switching function allows 10Mbps, 100Mbps, Full-duplex and Half-duplex devices to communicate on the same network without having to replace any infrastructure.
