Problem Description

1. MOSFET failure caused by malfunction of the TEC driver LX1810. MOSFET is driving the PELTIER controlling trunk laser resulting in failure of the card.

2. Component-related failures due to MSA 300 pin optical module used as client optical interface on Transponders

Background

These issues were found at a customer site, verified through EFA of failed units and will be corrected through an ECO to address the affected products once returned from the field.
Since the End of Sales date has passed for this product, Cisco will be offering next generation replacements to customers.

Problem Symptoms

1. Failure mechanism is generated by a design flaw in the chip that induces hot electrons in some sensitive areas, which can result in component failure leading to the shutdown of the trunk laser.

2. A number of modules have failed for insufficient solder which was isolated to a particular lot manufactured in 2005, which accounts for ~25% of the total shipments to customers. If the MSA 300 PIN fails, this will result in shutdown of the client laser.

Workaround/Solution

Currently Cisco System is offering customers an upgrade of the 15454-10T-L1-xx.x, 15454-10M-L1-xx.x, 15454E-10T-xx.x and 15454E-10M-xx.x products to the Enhanced FEC Transponders 15454-10E-L1-xx.x (Multi-Rate Txp 10G/10GE - EFEC - 4 Channel Tunable) and the Enhanced FEC Muxponders 15454-10ME-xx.x (4 x 2.5 Gbs - 10Gbs Muxpdr - EFEC - 4 Channel Tunable).

To obtain replacement cards, Customers will need to collect the serial numbers corresponding to the Products Affected above, then determine the appropriate replacement Product ID (PID) by comparing their products against the Product Upgrade Matrix section of this Field Notice.

Customers upgrading from the 15454-10T-L1-xx.x or 15454E-10T-xx.x to the 15454-10E-L1-xx.x must request both the individual transponder PIDs along with an equal number of the ONS-XC-10G-S1= (XFP - OC192/STM64/10GE - 1310 SR - SM LC) as these boards require XFP's to be functional. For customers upgrading from the 15454-10M-L1-xx.x or 15454E-10M-xx.x, please remove and reuse all SFP's from the existing units as they are compatible with the replacement 15454-10ME-xx.x=.

Note: Lead times on the replacement products is expected to be from 8-12 weeks on some modules due to limited material supply.

Note: The Enhanced FEC products have a minimum software requirement of 15454 R4.7 SW. Customers need to verify the software release currently working on the network together with the Cisco Transport Manager (CTM) release to verify any compatibility issue between the Network Element (NE) software and the Element Management software using the CTM Release Notes available on Cisco.com.
