Troubleshooting

POST diagnostics

The switch performs a series of tests as part of its power-up procedure. The POST diagnostic program performs checksum tests on the boot firmware in PROM and the switch firmware in flash memory, internal data loopback tests on all ports, and access and integrity tests on the ASIC.

During the POST, the switch logs any errors encountered. Some POST errors are critical, others are not. The switch uses the Heartbeat LED and the Logged-In LED to indicate switch and port status. A critical error disables the switch so that it does not operate. A non-critical error allows the switch to operate, but disables the ports that have errors. Whether the problem is critical or not, contact your HP Authorized Maintenance Provider.

If there are no errors, the Heartbeat LED blinks at a steady rate of once per second. If a critical error occurs, the Heartbeat LED shows an error blink pattern and the System Fault LED will illuminate. If there are non-critical errors, the switch disables the failed ports and flashes the associated Logged-In LEDs.

Heartbeat LED blink patterns

The Heartbeat LED indicates the operational status of the switch. When the POST completes with no errors, the Heartbeat LED blinks at a steady rate of once per second. When the switch is in maintenance mode, the Heartbeat LED illuminates continuously. See “Maintenance mode options” on page 47 for more information about maintenance mode. All other blink patterns indicate critical errors.

The Heartbeat LED shows an error blink pattern for the following conditions:
