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.
Beginning with firmware revision 5.15.0, the Auto
Diagnosis and Recovery feature is provided to help diagnose "System Error
Pause" conditions when they occur. Fault codes and resolution information are
provided here.
The following table provides the page numbers for each procedure.

- Periodic maintenance requires the air intake screen be inspected and/or
cleaned once every 3 months. Have spare air intake screens onsite so
that replacements are available when needed for cleaning.
