If the data dump is not successful, do not continue; contact your

technical support organization. A data dump problem must be

corrected before proceeding.

Verify that the ENB/DIS switch is set to ENB on all of the cards in the

network area of the Core/Network module.

Press the MAN INT button on the CP card. Watch the initialization

process. Make sure the CNI and 3PE cards are auto-enabled. (The

faceplate LEDs should go out.)

Note: If the network loop corresponding to a CNI port is not enabled, the

LED for that port may not go out.

Check for dial tone. If there is no dial tone, do the following:

Perform a visual check of the Core/Net module. Verify that each

card is in the correct slot. Verify that all cards are seated, all

ENB/DIS switches are set to ENB, and all red LEDs are off.

Verify that all cables are properly and securely connected in the

front and rear of the module.

Check the status of the CNI card with LD 135 "STAT CNI" and

ensure that it is software enabled.

If the CNI card is software disabled, test the card with LD 135

"TEST CNI c s."

If the test is successful, enable the card in LD 135, perform a data

dump with LD 43, and recheck the CNI status in LD 135.

Check for dial tone again.

If dial tone is still not present, press the MAN INT button on the CP

card. Watch the initialization process. Make sure the CNI and 3PE

cards are auto-enabled. (The faceplate LEDs should go out.)
