Fast EtherHub 3500 System User’s Guide
After power on, the hub automatically performs a diagnostic test. The diagnostic tests display results for the repeater board via the Partition/Disable LEDs on the front panel. Test results for the agent board can only be seen via a console connection to the serial port. The following table shows how test results for the repeater board are indicated by the Partition/Disable LEDs.

Table 5.16 Diagnostic Results for Repeater Board
The system tests each component one at a time. The corresponding indicator will display a blinking light (ON) after test completion to show which component failed the test. The unit will complete the test cycle even if a problem is detected on any component. If all Partition/Disable LEDs are off, then all the tested components have successfully passed diagnostics. You must have a console connected to serial port to view the results of diagnostic testing for the agent board.
