Description
Suppose that the testsb(8) command
running for system board (PSB) diagnosis
detects one of the errors listed below
during the period between power-off and
power-on of the SPARC M10 Systems
chassis or crossbar box chassis. In this
case, the command terminates, leaving
the power to the chassis on.
- The DC-DC converter (DDC) in the
chassis is faulty.
Error log: Msg: Power-on failure
- The circuit that monitors cooling
components within the chassis is
abnormal.
Error log: Msg: LLC protection circuit
test error
- A crossbar cable is connected to the
crossbar unit (XBU) within the chassis
in an invalid combination.
Error log: Msg: XB CABLE configuration
error
You can determine the occurrence of this
phenomenon from the above error log
and the output of the showboards(8)
command. If this phenomenon has
occurred, the command outputs "y" for
[Pwr] and "Failed" for [Test].
[Example] If the power to the SPARC
M10-4S chassis is on and the system
board diagnosis indicates an error

When the fan speed is switched due to a
change in the intake air temperature, an
error log indicating an abnormal fan
speed may be erroneously registered for
a fan that is not faulty.
Workaround
There is no effective workaround.
Check the error log and perform
maintenance on the component.

There is no effective workaround.
[How to restore]
Execute the replacefru(8) command and
select the fan for which the error log has
been registered.
Follow the replacement instructions on
the maintenance menu, without
replacing the fan.
