Description
In SPARC M10-1, if the power supply
unit (PSU) has a redundant configuration
and the power cable connected to one of
the power supply units is pulled out, a
PSU error may be erroneously detected,
and the SPARC M10-1 chassis Check
LED (amber) may go on. At this time,
executing the showlogs error command
outputs the "Msg: PSU failed" log.
AC input power may be incorrectly
determined to have a mix of 100 V and
200 V if any of the power supply units
(PSU) in redundant configuration
triggers an AC input error, and then
power loss/recovery repeats in a short
time. Consequently, though system
operation may continue when power is
recovered, two PSUs are degraded with
the "PSU shortage (power off started)"
message displayed and the system stops.
Workaround
There is no effective workaround.
[How to restore]
Use either of the following procedures.
- How to restore 1
Turn off the power to the SPARC M10
chassis connected to the PCI expansion
unit. Then disconnect both PCI
expansion unit power cables (AC OFF).
Then, wait for 30 seconds to reconnect
the cables (AC ON).
- How to restore 2
Perform pseudo active replacement of
the PSU in which the error has been
detected (temporarily remove the PSU
and then reinstall it). When performing
pseudo replacement of the PSU, use the
replacefru(8) command. Note that the
fieldeng privilege is required to execute
the replacefru(8) command.
There is no effective workaround.
Replace the faulty PSU.
