DLP- D255 Cross-Connect Card Side Switch Test

Step 9 After the node icon turns green (within 1 to 2 minutes), double-click it. On the shelf graphic, observe

the following:

• The previous standby TCC2/TCC2P card has a green ACT LED.

• The previous active TCC2/TCC2P card LEDs go through the following LED sequence: NP (card not

present), Ldg (software is loading), amber SBY LED (TCC2/TCC2P card is in standby mode). The

LEDs should complete this sequence within 5 to 10 minutes.

Step 10 Verify that traffic on the test set connected to the node is still running. If a traffic interruption occurs, do

not continue, refer to your next level of support.

Step 11 Repeat Steps 2 through 10 to return the active/standby TCC2/TCC2P cards to their configuration at the

start of the procedure.

Step 12 Verify that the TCC2/TCC2P cards appear as noted in Step 5.

Step 13 Return to your originating procedure (NTP).

DLP-D255 Cross-Connect Card Side Switch Test

Caution Always wait 60 seconds between cross-connect card (side) switches to allow the system to stabilize. This

is applicable to all the types of side switches (soft reset or manual switch using CTC or TL1). This

condition is also applicable to all the cross-connect types (XC-10G / XC-VXC-10G / XC-VXL-2.5G /

XC-VXL-10G / XC-VT).

Step 1 From the View menu, choose Go to Network View.

Step 2 Click the Alarms tab.

a. Verify that the alarm filter is not on. See the “DLP-D227 Disable Alarm Filtering” task on

page 19-26 as necessary.

b. Verify that no unexplained alarms appear on the network. If unexplained alarms appear, resolve

them before continuing. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide if necessary.

Step 3 Click the Conditions tab. Verify that no unexplained conditions appear on the network. If unexplained

conditions appear, resolve them before continuing. Refer to the Cisco ONS 15454 SDH Troubleshooting

Guide if necessary.

Step 4 On the network map, double-click the node containing the cross-connect cards that you are testing to

open it in node view.

Purpose This task verifies that the XC-VXL-10G, and XC-VXL-2.5G, or

XC-VXC-10G cards can effectively switch service (active to standby and

standby to active).

Tools/Equipment The test set specified by the acceptance test procedure, connected and

configured as specified in the acceptance test procedure.
