Sun Fire[tm] 4800/4810 Server: Repair Procedures
This section provides the most common repair procedures for the
Sun Fire 4800/4810, which are included in the  Sun
Fire 6800/4810/4800/3800 Systems Service Manual (805-7363).
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.
