TROUBLESHOOTING
If the Console Switch is not working properly, consider the suggestions below to see if a solution can be found.
Problem

Cannot Connect to port/device
Commands entered from front panel
keypad are not accepted
SERIMUX will not accept username

Buffer
If the passwords or other important parameters are not available, the SERIMUX Console Switch can be re-initialized to the default
settings (see "Initialize SERIMUX Console Switch to default settings" on page 27).
Caution: During initialization, the customer modified parameter values will be replaced with the factory
default values; all ports will be placed in buffer mode; all passwords will be erased.
