Diagnostics/Troubleshooting 4-7
Power-On-Self-Test (POST)
The POST diagnostic program performs the following basic tests:
• checksum tests on the Boot firmware located in a PROM and the main
Switch firmware located in FLASH memory
• functional hardware tests on internal Switch memory
• various read/write register and loopback data-path tests on the Switch logic
• Frame Bus and Auto Route logic tests
• Auto-Connect and Class 1 Connect logic tests
• Switch Management port logic
• Arbitrated Loop tests
Heartbeat LED Blink Patterns
Normal (all pass)
If all POST diagnostics pass, the Switch will go to normal operation and the
Heartbeat LED will blink at a steady rate of one (1) blink per second.
Failure Blink Patterns
The Heartbeat LED indicates the error by blinking a series of blinks, pausing for
three seconds, then repeating the blinks. The number of blinks between the three-
second pauses indicates the error. The blinks are at about twice the speed of the
normal Heartbeat.
Test/Failure Descriptions
The following paragraphs describe the tests and their failure indication. If any
POST errors occur, notify Ancor Customer Service or your authorized
maintenance provider. Refer to Appendix B for information about how to
contact Ancor Customer Service.
