Configuration File System Error Blink Pattern
A configuration file system error blink pattern is 4 blinks followed by a two second
pause. The 4-blink error pattern indicates that a configuration file system error has
occurred, and that the configuration file must be recreated. Refer to ”Recovering a
Switch” on page 5-12 for more information.
To recreate the configuration file, do the following:
1. Open a Telnet session and use the Shutdown command to close activity on
the switch, then power down the switch. Refer to the ”Shutdown Command”
on page B-81.
2. Place the switch in maintenance mode. Press and hold the Maintenance
button for 2–4 seconds. Refer to ”Recovering a Switch” on page 5-12 for
more information about placing the switch in maintenance mode.
3. Establish a Telnet session with the switch using the default IP address
10.0.0.1.
telnet 10.0.0.1
4. Enter the account name (prom) and password (prom), and press the Enter
key.
Sanbox2 login: prom
Password:xxxx
[username@host:Itasca]% telnet 10.0.0.1
Trying 10.0.0.1...
Connected to 10.0.0.1.
Escape character is '^]'.
CAUTION! Recreating the configuration file will delete all switch configuration
settings.
