Call your ProCurve Networking authorized network reseller, or use the electronic support services from HP to get assistance. For Warranty service, see the “Software End User License Agreement and Hardware Limiited Warranty” booklet. . A switch hardware failure has occurred. All the LEDs will stay on indefinitely. Try power cycling the switch. If the fault indication reoccurs, the switch may have failed. Call your ProCurve Networking authorized network reseller, or use the electronic support services from HP to get assistance. For Warranty service, see the “Software End User License Agreement and Hardware Limiited Warranty” booklet. . The switch has experienced a software failure during self test. 1. Try resetting the switch by pressing the Reset button on the front of the switch, or by power cycling the switch. 2. If the fault indication reoccurs, attach a console to the switch (as indicated in chapter 2) and configure it to operate at 9600 baud. Then, reset the switch. Messages should appear on the console screen and in the console log identifying the error condition. You can view the console log at that point by selecting it from the console Main Menu or by typing “Show log” at the Manager command prompt (#). If necessary to resolve the problem, contact your ProCurve Networking authorized network reseller, or use the electronic support services from HP to get assistance. For Warranty service, see the “Software End User License Agreement and Hardware Limiited Warranty” booklet. . The network port for which the LED is flashing has experienced a self test or initialization failure. Try power cycling the switch. If the fault indication reoccurs, the switch port may have failed. Call your ProCurve Networking authorized network reseller, or use the electronic support services from HP to get assistance. For Warranty service, see the “Software End User License Agreement and Hardware Limiited Warranty” booklet. If the port is a mini-GBIC, verify that it is one of the mini-GBICs supported by the switch. Unsupported mini-GBICs will be identified with this fault condition. The supported mini-GBICs are listed in Chapter 2, “Installing the Switch” on page 2-18. The mini-GBICs are also tested when they are “hot-swapped”—installed or changed while the switch is powered on. To verify the port has failed, remove and reinstall the mini-GBIC without powering off the switch. If the port fault indication reoccurs, you will have to replace the mini-GBIC. Check the event log to see why the mini-GBIC failed. continued on the next page Troubleshooting Diagnosing with the LEDs Tip Problem Solution The network connection is not working properly. . Try the following procedures: • For the indicated port, verify that both ends of the cabling, at the switch and the connected device, are connected properly. • Verify the connected device and switch are both powered onand operating correctly. • Verify you have used the correct cable type for the connection: – For twisted-pair connections to the fixed 10/100 or 10/100/1000 ports, if the port is configured to “Auto” (auto negotiate), either straight-through or crossover cables can be used because of the switch’s “Auto-MDIX” feature and the Auto MDI/MDIX feature of the 10/100/1000-T port.

Ingeneral,for connectinganendnode(MDIport)totheswitch, usestraight-throughcable;for connectingtoMDI-X ports onhubs, otherswitches,androuters,use crossover cable. – For fiber-optic connections, verify the transmit port on the switch is connected to the receive port on the connected device, and the switch receive port is connected to the transmit port on the connected device. • For the dual-personality 10/100/1000-T ports, be sure a mini-GBIC is not installed in the associated slot. • For 1000Base-T connections, verify the network cabling complies with the IEEE 802.3ab standard. The cable should be installed according to the ANSI/TIA/EIA-568-A-5 specifications. Cable testing should comply with the stated limitations for Attenuation, Near-End Crosstalk, Far-End Crosstalk, Equal-Level Far-End Crosstalk (ELFEXT), Multiple Disturber ELFEXT, and Return Loss. The cable verification process must include all patch cables from any end devices, including the switch, to any patch panels in the cabling path. • Verify the port has not been disabled through a switch configuration change. You can use the console interface, or, if you have configured an IP address on the switch, use the Web browser interface to determine the state of the port and re-enable the port if necessary. • Verify the switch port configuration matches the configuration of the attached device. For example, if the switch port is configured as “Auto”, the port on the attached device also MUST be configured as “Auto”. Depending on the port type, twisted-pa...
