APPENDIX A Intel Express 460T Standalone Switch Users Guide Troubleshooting/FAQs I booted the switch, and the status LED stays orange, is something wrong? By default, the switch is in BootP mode, and the LED stays orange while the switch waits for an IP address from the BootP server. In order to proceed with the boot, either bypass the BootP phase (refer to the Quick Start guide for instructions), or manually assign an IP address. If the switch doesn't receive an IP address from the BootP server within ten minutes, it will continue the boot process as normal. How can I set the speed or duplex on individual ports? Normally the switch handles all connections automatically but if you need to force speed or duplex, (for example, to accommodate older devices that don't support autonegotiation) use the Local Management or Web Device View. When I set the 460T to autonegotiate with flow control enabled and try to connect to another device, there is no link. Why? Check the settings of the other device and disable flow control. If you want to use flow control on the port, force the speed, duplex, and flow control settings so that they match. I've connected the cable but the left LED (link) is off. Why? • Remove the cable and plug it in again. Wait up to six seconds for a link. • Make sure you're using the correct type of cable (straight-through-MDI or crossover-MDI-X) for the device you want to connect to. If you're using the wrong cable, the link LED will not come on. • Make sure the device you've connected to a port is a 10Base-T or 100Base-TX device. The Express 460T Standalone Switches don't support 100Base-T4 devices running at 100Mbps. However, they do support T4 devices running at 10Mbps. • Check the speed and duplex settings on the PC's network adapter. • The cable is defective. The port's left LED (link) is on but I'm not seeing any activity when I try to ping a device on that port. Why? • The port could be disabled through management. Go into the Local Management or Web Device view to enable the port and try pinging the device again. • The port could be partitioned (auto-disabled). This condition is usually caused by a malfunctioning network adapter or an overloaded network segment. The switch will wait until it stops receiving collisions then 124 clear the port automatically. 460T Appendix A.p65 124 4/19/00, 1:48 PM
