Sun Fire[tm] E20K / E25K Server: Repair Procedures
This section provides tips (when available) for the most common repair procedures for the Sun Fire E20K / E25K, which are included in the Sun
Fire E25K / E20K Systems Service Manual (817-4138).
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 available tips
for each procedure.
