TROUBLESHOOTING

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

Problem

Cause

No Front Panel LEDs are illuminated

No power to SERIMUX

SERIMUX is not working properly

Poor Connections

 

Port not configured correctly

 

Ports not initialized

 

 

Cannot Connect to port/device

Port settings not correct

 

Wrong cable adapter used

 

Connections are loose

 

 

Commands entered from front panel

Buttons are being pressed too rapidly

keypad are not accepted

 

 

 

 

SERIMUX will not accept username

Usernames and passwords are case

or password

sensitive

Cannot access user menu on a port

Port is configured as host port

I cannot access the View Port Data

Only the ROOT user can access this (see

Buffer

page 14)

Solution

Check all power connections

Verify that all cables are securely connected

Verify that the port configuration matches that of the device connected

Power-up the CPUs first, then the

SERIMUX

Verify proper communication settings (pg 8)

Verify that adapter is one specified in Appendix C.

Verify that all cable connections are secure

Try again but slow down the button sequence- approx 1/2 sec between each press.

Verify characters used and enter again.

Configure port as user port. (pg. 10) Login as the ROOT user

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.
