Step 10 Click Finish . On the Circuits tab, the circuit status for the Roll From port changes from DISCOVERED
to ROLL_PENDING.
Step 11
Click the Rolls tab ( Figure 17-5 ). For the pending roll, view the Roll Valid Signal status. When one of
the following conditions are met, continue with Step 12 .
• If the Roll Valid Signal status is true, a valid signal was found on the new port.
•
If the Roll Valid Signal status is false, a valid signal was not found. Wait until the signal is found
before continuing with the next step. To cancel the roll, see the
“DLP-H189 Cancel a Roll” task on
page 17-84 .
• The roll is a one-way destination roll and the Roll Valid Signal is false. It is not possible to get a
“true” Roll Valid Signal status for a one-way destination roll.
Note You cannot cancel an automatic roll after a valid signal is found.
• You can force a signal onto the Roll To circuit by using the Force Valid Signal button. If you choose
Force Valid Signal, traffic on the circuit that is involved in the roll might drop depending on
conditions at the other end of the circuit when the roll is completed. You must force a signal if the
circuits do not have a signal or have a bad signal and you want to complete the roll.
Note
For a one-way destination roll in manual mode, you do not need to force the valid signal.
