Steady illumination indicates that the switch is in force PROM mode, which returns 
the switch IP address to 10.0.0.1. From force PROM mode, you may reload 
firmware, reset the password to the factory default, and remove a corrupt 
configuration.

An internal firmware failure blink pattern is 2 blinks per second followed by a two 
second pause. The 2-blink error pattern indicates that the firmware has failed, and 
that the switch must be reset.

A fatal error blink pattern is 3 blinks per second followed by a two second pause. 
The 3-blink error pattern indicates that a fatal error has left the switch inoperable. 
If a fatal error occurs, contact your authorized maintenance provider. 

A configuration file system error blink pattern is 4 blinks per second 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.

To recreate the configuration file, do the following:

1.

Place the switch in force PROM mode by pressing and holding the 
Reset/Force PROM button. Refer to
