3 Troubleshooting

If there is an operating problem with the Express Switching Hub, incorrect configuration or cabling is probably the cause. Try the troubleshooting steps below in order:

1Verify that your cables are wired correctly. This is the most common problem. Use a UTP crossover cable to directly connect another switch, server, or workstation to the switch. Use a straight- through cables when connecting to a repeater. See page 8 for more information.

2Make sure the unit is plugged into a grounded, functioning AC outlet providing between 90 VAC and 264 VAC at 50/60 Hz.

3Review the Link LEDs of other devices to ensure that those ports you believe should be functioning are properly attached to the switch with a Category 5 UTP cable.

4Review the switch’s Link LEDS to ensure that ports you believe should be functioning are properly configured, and not disabled or partitioned.

5If you configured a port for full duplex, make sure the device on the other end is configured for full duplex and is capable of transmitting in full duplex. Remember, you must have a point-to- point connection for a full-duplex link. Most repeaters aren’t capable of full duplex.
