Troubleshooting

This chapter describes how to troubleshoot your V1410-8 Switch, V1410-16
Switch, V1410-24 Switch, and V1410-24-2G Switch. This document describes
troubleshooting from a hardware perspective.

This chapter describes the following:

■

basic troubleshooting tips (

page 3-1

)

■

diagnosing with the LEDs (

page 3-3

)

■

hardware diagnostic tests (

Basic Troubleshooting Tips

Most problems are caused by the following situations. Check for these items
first when starting your troubleshooting:

■

Connecting to devices that have a fixed full-duplex configuration.

The RJ-45 ports are configured as “Auto”. That is, when connecting to
attached devices, the switch operates in one of two ways to determine the
link speed and the communication mode (half duplex or full duplex):

•

If the connected device is also configured to Auto, the switch will
automatically negotiate both link speed and communication mode.

•

If the connected device has a fixed configuration, for example
100 Mbps, at half or full duplex, the switch will automatically sense
the link speed, but will default to a communication mode of half
duplex.

C a u t i o n

Because the switches behave in this way

(in compliance with the IEEE

802.3 standard)

, if a device connected to the switch has a fixed configu-

ration at full duplex, the device will not connect correctly to the switch.
The result will be high error rates and very inefficient communications
between the switch and the device.

Ensure all devices connected to the switches are configured to auto
negotiate, or are configured to connect at half duplex (all hubs are
configured this way, for example).
