4 External I/O Expansion Unit Product Notes for SPARC Enterprise T5xxx Servers • March 2010
lists open issues for the External I/O Expansion Unit.
Workaround
Reduce the ambient temperature if it is at or exceeds the
maximum (38˚C/100˚F). Note: the ambient temperature is
measured at the intakes of the PSUs.
Multiple messages are generated if the ambient temperature
continuously fluctuates above and below the maximum
value.
A single message is generated if the ambient temperature
exceeds the maximum without fluctuating above and below
the maximum.
If the temperature is within normal limits, recover with this
procedure:
• Power off both power supply units on the External I/O
Expansion Unit.
• When the DC Power LED (
units turn off, disconnect both AC cables.
• After 10 seconds or more, reconnect the AC cables.
• Power on the External I/O Expansion Unit.
If the recovery procedure fails, contact a certified service
engineer.
To prevent this problem, be sure to turn off the power
supply units in the External I/O Expansion Unit before you
disconnect the AC cables.
If this problem occurs, verify that the AC cables are properly
connected, then turn on the power supply units. Issue the
following command to clear the fault and reset the error
LEDs on the power supply units:
set clear_fault_action=true /SYS/IOX@nnnn/PSx
There is no workaround at this time.
