Fatal Post Error Blink Pattern; Configuration File System Error Blink Pattern; Over-Temperature Blink Pattern - HP StorageWorks SN6000 Installation And Reference Manual

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.

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.
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.
SN6000 $> admin start
4. Restore the configuration. When the restore is complete, the switch will reset.
SN6000 (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.
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.
