Troubleshooting

This chapter describes how to diagnose and solve problems that may arise with the operation of an 6412M-25-TP module. These problems are signaled by the following conditions:

The Port Status LED of a port does not light green, or is blinking, when idle (connected and enabled but no traffic).

The Port Status LED of a port does not light yellow during data transmission.

The Reset LED is either ON or blinking.

The Wrong Slot LED is ON.

Before you start troubleshooting, be sure to carry out the procedure described in “Verifying LED Operation.”

When instructed to replace an 6412M-25-TP module, proceed as described in “Replacing 6412M-25-TP Modules” on page 4-10.

Verifying LED Operation

Before troubleshooting an 6412M-25-TP module, verify that all LEDs on the module are functioning properly:

ONcore

Press

the

LED

Test button

on the

Fault-Tolerant

Controller module in

 

the

ONcore

hub.

 

 

 

 

CELLplex 4000

Press

the

RESET

button

on

the base unit. Note that this action will
