How to Remove the ID SEEPROM
Module
There are two serially electrically erasable and programmable read-only memory
(SEEPROM) modules on the main logic board. One SEEPROM contains data about
the main logic board itself; this data is used by the RSC software for diagnostic
purposes and cannot be removed from the board. (For more information about using
the RSC software, see the RSC documentation and the Sun Fire 280R Server Owner’s
Guide.) The other SEEPROM contains the system host identification (ID) and
Ethernet address, and is removable.
This section explains how to remove a functioning ID SEEPROM module so that you
can install it on a new main logic board, thereby preserving the system’s host ID
information. If you are replacing a defective ID SEEPROM module and want to
retain the same host ID, consult your authorized Sun sales representative or service
provider for assistance with programming the new ID SEEPROM module with the
existing host ID and Ethernet address.
