Sun Fire[tm] E4900 Server: Repair Procedures

This section provides the most common repair procedures for the Sun Fire E4900, which are included in the Sun Fire E6900/E4900 Systems Service Manual (817-4120).

Clustered Hardware Note: When repairing a clustered system, you should replace server components by first switching over the data services to the functioning server, halting the host to be serviced, powering down the host, and then performing the hardware procedure to replace the component. Following the procedure, the logical hosts should be switched back to the default masters.

The following table provides the page numbers for each procedure.
