NTI SERIMUX SERIES CONSOLE SWITCH

INTERCONNECTION CABLE WIRING METHOD

The cable connecting the terminals and devices to the SERIMUX must be terminated with RJ45 connectors and must be wired according to the EIA/TIA 568 B industry standard. Wiring is as per the table and drawing below.

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.
