Installing the Switch 408
Installation Procedures
Connect no devices that have a fixed full-duplex
configuration. Because the switch 408 complies with
the IEEE 802.3u standard, if a device connected to the
switch has a fixed configuration of full duplex, the device
will not connect correctly to the switch. Make sure all
devices connected to the Switch 408 are configured to
auto negotiate, or are configured to connect at half
duplex. For more information, see the "Basic Trouble-
shooting Tips" in chapter 3, "Troubleshooting".
