wire connects to Rx on one end and Tx on the other.

 

 

ACT LED not blinking

When the CoreBuilder 7000 family ATM switch is activated, the switch module and

 

interface cards ACT LEDs should be blinking. If not, verify that the switch module and

 

interface cards are properly inserted. Make sure that the control terminal is connected to
