WWN card removal and replacement

There are two WWN cards located beneath the WWN bezel (logo plate). As you are facing the bezel on
the non-port-side of the chassis, WWN 1 is located on the left side, and WWN 2 is on the right. Before
replacing cards, refererence RASlog messages and use the WWN Recovery Tool (wwnrecover) as
directed in the following sections to recover WWN cards. The tool will direct you to contact customer
support if recovery fails. In these cases, Brocade Support will determine whether one or both WWN
cards need replaced and will request the partner or OEM to send WWN cards from FRU inventory to
the nearest Brocade Support office to be reprogrammed.
This section provides information on RASlog messages indicating WWN card problems, the WWN
Recovery Tool, and complete steps to remove and replace WWN cards.
