Problem Description

Some 15454-OTU2-XP, 15454-10GE-XP and 15454-10GE-XPE cards assembled with faceplates and heatpipes by a certain vendor could have mechanical interference issues when plugging the last card into a fully equipped 15454, M2 or M6 chassis. The heatpipes assembled on some cards exceeds the maximum height and can interfere with adjacent cards.

Improved heat-pipe assembly and new version faceplates are being released to provide a greater clearance during card insertion.

If you are using TL1 commands.

1. >ACT-USER::
2. >RTRV-INV::ALL
3. >CANC-USER::

Compare the information from the TL1 inventory command against the serial number validation tool provided.

A serial number validation tool has been provided so customers can easily check their hardware's serial number to identify affected units.
