Fatal POST error blink pattern A system error blink pattern is 3 blinks followed by a 2-second pause. The 3-blink error pattern indicates that a POST failure or a system error has left the switch inoperable. If a system error occurs, contact your authorized maintenance provider. Momentarily press and release the Maintenance button to reset the switch. 2 seconds Configuration file system error blink pattern A configuration file system error blink pattern is 4 blinks followed by a 2-second pause. The 4-blink error pattern indicates that a configuration file system error has occurred, and that the configuration file must be restored. 2 seconds To restore the switch configuration: 1. Establish communications with the switch using Telnet. Enter one of the following on the command line: telnet xxx.xxx.xxx.xxx or telnet switchname where xxx.xxx.xxx.xxx is the switch IP address and switchname is the switch name associated with the IP address. 2. A Telnet window opens prompting you for a login. Enter an account name and password. The default account name and password are admin and password respectively. 3. Open an admin session to acquire the necessary authority. 8/20q FC Switch $> admin start 4. Restore the configuration. When the restore is complete, the switch will reset. 8/20q FC Switch (admin) $> config restore If a configuration does not exist, enter the config backup CLI command, then enter the config restore command. Over-temperature blink pattern An over-temperature blink pattern is 5 blinks followed by a 2-second pause. The 5-blink error pattern indicates that the air temperature inside the switch has exceeded the failure temperature threshold. 2 seconds If the Heartbeat LED shows the over-temperature blink pattern: 1. Inspect the switch vents. Are the intake and exhaust vents clear? • Yes-Continue. • No-Remove any debris from fan intake and exhaust if necessary. If the condition remains, continue. 2. Consider the ambient air temperature near the switch and clearance around the switch. Make necessary corrections. If the condition remains, power down the switch and contact your authorized maintenance provider. 8/20q Fibre Channel Switch installation and reference guide 47
