    Troubleshooting This chapter describes how to diagnose and resolve operating problems with your hub. Additionally, if you have an HP J3133A AdvanceStack 8U/16U SNMP Module installed, you can use ASCII console software for certain diagnostic functions to troubleshoot the hub.

  • Page 27: Diagnosing With The Leds

    During the self-test, all of the LEDs turn on for a short time. If an HP Transceiver module is properly installed, the AUI/Xcvr LED stays lit. If an HP Transceiver module is not installed, the AUI/Xcvr LED turns off. When the self-test completes successfully, the LEDs go into their normal operational states.

  • Page 28: Led Error Indications

    For hub-to-hub connections, set the switch to MDI. For hub-to-PC connections, set the switch to MDI-X. Verify that the HP Transceiver Module is firmly inserted into the AUI/Xcvr slot into the back of the hub. See the documentation accompanying the HP Transceiver module for more troubleshooting information.
