Purpose

This document helps the user to prepare an Infiniband Switch for replacement and collect information required by Oracle Support / On-site team prior to Dispatch of a replacement IB Switch part.

Scope

- The document distribution is EXTERNAL since it needs to be shared with and used by the Customer-admin, as well as referenced by Partners, Field Engineers, and Oracle Support.

- Where Oracle Support has confirmed the need for an IB Switch replacement (whether that replacement will be performed by Customer-admin, Partner or Oracle Field Engineer), Customer-admin is requested to confirm by updating in MOS SR-notes that all the pre-check actions in this document have been completed - by copying/pasting the requested checklist(s) into the SR in MOS - prior to Oracle Dispatching the Part for replacement.

- Oracle Support will not Dispatch until these checks have been performed unless customer has given a clear statement acknowledging the risks of not performing these checks prior to replacement.
