McDATA 4314 Manual Do Utilizador

Diagnostic information about the switch is available through the switch 
module LEDs and the external port LEDs. Diagnostic information is also 
available through the EFCM BASIC and CLI event logs and error displays.

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 System Fault 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.

The Input Power LED illuminates to indicate that the switch logic circuitry is 
receiving proper voltages. If the Input Power LED is extinguished, contact 
your authorized maintenance provider.

The System Fault LED illuminates to indicate that the switch module logic 
circuitry is overheating or that a POST error has occurred. If the System Fault 
LED illuminates, contact your authorized maintenance provider.
