Section 5

Diagnostics/Troubleshooting

Diagnostic information about the switch is available through the chassis LEDs and the port LEDs. Diagnostic information is also available through the SANbox Manager and CLI event logs and error displays. This section describes two types of diagnostics: Power On Self Test (POST) and chassis. POST diagnostics describe the Heartbeat LED and the port Logged-In LED indications. Chassis diagnostics cover power supply and fan diagnostics as well as chassis over temperature conditions. This section also describes how to use force PROM mode to recover a disabled switch.

5.1

POST Diagnostics

The switch performs a series of Power On Self Tests (POST) 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 fatal, others are non-fatal. The switch uses the Heartbeat LED and the Logged-In LED to indicate switch and port status. A fatal error disables the switch so that it will not operate. A non-fatal error allows the switch to operate, but disables the ports that have errors. Whether the problem is fatal or non-fatal, contact your authorized maintenance provider.

If there are no errors, the Heartbeat LED blinks at a steady rate of once per second. If a fatal error occurs, the Heartbeat LED will show an error blink pattern. If there are non-fatal errors, the switch disables the failed ports and flashes the corresponding Logged-In LEDs. Refer to ”Heartbeat LED Blink Patterns” on page 5-1for more information about Heartbeat LED blink patterns.

Heartbeat LED Blink Patterns

5.1.1.1

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.
