1. Prepare an Infiniband Switch in Exalogic rack for replacement

2. Collect information required by Oracle Support / On-site team prior to Dispatch of a replacement IB Switch part for Exalogic rack.


This 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.

Once Oracle Support has confirmed the need for an IB Switch replacement (Replacement will be performed by 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.
