Power-On Self Test Diagnostics

The switch performs a series of tests as part of its power-up procedure. The POST diagnostic program performs the following tests:

„Checksum tests on the boot firmware in PROM and the switch firmware in flash memory

„Internal data loopback test on all ports

„Access and integrity test 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 will not operate. A non-critical error allows the switch to operate, but disables the ports that have errors. If two or more ports fail the POST, the entire switch is disabled. Whether the problem is critical or not, contact your 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 will show 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. Refer to “Heartbeat LED Blink Patterns” on page 5-3for more information about Heartbeat LED blink patterns.

5.2.1

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 steady rate of once per second. When the switch is in maintenance mode, the Heartbeat LED illuminates continuously. Refer to “Recovering a Switch Using Maintenance Mode” on page 5-13for more information about maintenance mode. All other blink patterns indicate critical errors. In addition to producing a Heartbeat error blink patterns, a critical error also illuminates the System Fault LED.

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

„1 blink - Normal operation

„2 blinks - Internal Firmware Failure Blink Pattern

„3 blinks - Fatal POST Error Blink Pattern

„4 blinks - Configuration File System Error Blink Pattern

„5 blinks - Over Temperature Blink Pattern
