SPARC M10 Systems Product Notes for the latest XCP version.
Precautions for power supply unit replacement
Caution - Do not forcibly push the power supply unit into its slot. Using excessive
force may damage the FRU and chassis.
There are two power supply units. Thus, the system can continue operating even
■
if one of the units fails. Do not, however, operate the system for an extended
period while one unit has failed.
When replacing multiple power supply units, replace one unit at a time. If
■
redundancy of the power supply units cannot be secured, perform maintenance
with the inactive/cold (system stopped) method.
The type of power supply unit varies depending on the number of CPU clocks.
■
Precautions for fan unit replacement
When you replace multiple fan units, do so one by one. If redundancy of the fan
■
units cannot be secured, perform maintenance using the inactive/cold (system
stopped) method.
The fan units have a redundant configuration. Thus, the system can continue
■
operating even if one of the fan units fails. Do not, however, operate the system
for an extended period with one failed unit. Replace any failed fan unit immediately.
Precautions for PCIe card replacement
Before replacing the PCIe card, stop the system and remove the PCIe riser from
■
the motherboard unit.
Precautions for HDD backplane/operation panel replacement
Caution - When removing the HDD backplane and the operation panel, be careful
not to damage electronic components such as connectors.
