Chapter 3 Maintaining the Sun Fire Servers 3-83
■ After you replace the motherboard, you must use the servicetool command to
update the motherboard FRU information. See “Servicetool FRU Update
Procedure” on page 3-2.
■ The Sun Fire X4200/X4200 M2 servers use different motherboards. These cannot
be interchanged.
Note – The ILOM software on the GRASP board and the system BIOS on the
motherboard should be from the same software release, as documented in the Sun
Fire X4100/X4200 Servers Release Notes or the Sun Fire X4100 M2/X4200 M2 Servers
Release Notes (depending on whether or not yours is an M2 system). After replacing
the GRASP board or the motherboard, check the ILOM and system BIOS versions
against those documented in the release notes. If they are not from the same software
release, upgrade or downgrade the system BIOS (not the ILOM) accordingly. Once
the ILOM and system BIOS are back to matching versions, you can upgrade or
downgrade both to the desired versions.
3.12.18 Replacing a Power Supply
DC power supplies can be ordered as a factory installed option, or they can be
ordered and used to replace existing AC power supplies in the field.
Caution – It is a violation of UL rules to add a DC power supply into a chassis that
does not have the DC label indicating the correct safety information. (There is no
functional difference that would prevent this, aside from the DC label.)
Caution – Do not mix AC and DC power supplies in the same server.
Note – This component is a hot-swappable CRU and can be replaced by anyone.
Supported components and their part numbers are subject to change over time. For
the most up-to-date list of replaceable components for these servers, refer to:
