Important!

The LAN3 connection, identified as DLAN on the back of a shelf, or the control communications link between the main shelf and each subshelf failed.

To support more than one subshelf, the LAN3 port of the main shelf and of each subshelf must be connected to an Ethernet hub capable of supporting 100Mb operation. No special cable is required.

Visually check the control link connections between the shelf backplane DLAN connectors and the Ethernet hub (if equipped) for faulty connections or damage.

all Subshelves in the multishelf DCS system,

Then proceed to Step 6.

Important!

When the shelf is in the Maintenance Mode state, the IND display on the SYSCTL circuit pack faceplate shows MPx.x (where x.x is the generic number).

If the shelf is in the Maintenance Mode state, the default User IDs/passwords must be used to log in to the shelf. LUC01, LUC02, and LUC03 are the default privileged User IDs, and DMX2.5G10G is the default privileged password.

If required, perform the following to log in to the affected subshelf using the WaveStar® CIT TL1 Cut-Tthrough Mode.

  1. From the Network View, log into the shelf but this time click TL1, not Graphical.

  2. Select the Cut Through Execution Mode and click OK.

  3. Enter a default privileged User ID and password. Defaults are LUC01 and DMX2.5G10G, respectively.

STOP! End of Procedure.


6

Log in to the main shelf using the WaveStar® CIT and select View → Equipment to access each subshelf. Verify that the subshelf information is provisioned correctly.

If required, select Configuration → Equipment to access the subshelves and reprovision the subshelf information correctly.


7

From the System View, select Fault → Reset → System Controller.

Result:

The Reset System Controller window opens.
