Problem Description

The transmit (TX) power on the 15454-10E-L1-xx.x may degrade within a couple hours of installation of the unit if the pluggable port module (PPM) client ports are not pre-provisioned and put "In-Service". The Cisco Transport Controller (CTC) may report a positive transmit value. However, if measured with a power meter, the transmit rate would actually be negative.

Background

This issue was found during internal testing and has been corrected through a firmware update provided with CTC R6.01 or later.

Problem Symptoms

The transmit power on the 15454-10E-L1-xx.x may gradually degrade if the PPM client ports are not pre-provisioned and put "In-Service" upon installation. The performance tab for the 15454-10E-L1-xx.x in CTC may report a positive transmit value. However, if measured with a power meter the transmit value would actually be -20 dbm or more. LO-RXPOWER alarms may be noticed on the Alarm panel within CTC when this condition is present.

Workaround/Solution

1. In node view, double-click the TXP or MXP card where you want to provision PPM settings.

2. Click the Provisioning > Pluggable Port Modules tabs.

3. In the Pluggable Port Modules pane, click Create. The Create PPM dialog box appears.

4. In the Create PPM dialog box, complete the following:

   1. PPM - Choose the slot number where the SFP will be installed from the drop-down list.

   2. PPM Type - Choose the number of ports supported by your SFP from the drop-down list. If only one

      Note: The first port can be created only if the trunk is in the Out-of-Service and Management, Disabled (OOS-MA,DSBLD) service state (ANSI) or the Locked-enabled,disabled service state [ETSI].

5. Click OK. The newly created port appears on the Pluggable Port Modules pane. The row on the Pluggable Port Modules pane turns white and the Actual Equipment Type column lists the equipment name.

6. Verify that the PPM appears in the list on the Pluggable Port Modules pane. If it does not, repeat Steps 3 through 5.
