Problems Resolved in Version 1200 of the PCI Expansion Unit Firmware


Problems Resolved in Version 1200 of the PCI Expansion Unit Firmware
The following table lists the problems resolved in version 1200 of the PCI expansion unit firmware.
Table 7-6  Problems Resolved in Version 1200 of the PCI Expansion Unit Firmware
RTI No. RTIF2-150225-001
Model SPARC M10-1, SPARC M10-4, SPARC M10-4S
Description If the input voltage drops instantaneously on the system with the PCI expansion unit connected, a failure of the power supply unit (PSU) of the PCI expansion unit may be detected by mistake, and the CHECK LED (amber) of the PCI expansion unit may go on.
You can confirm this symptom by referring to the showlogs error -v command. If the execution result of the showlogs error -v command is "Msg: PSU failed" or "PSU failed(PSU) shortage)" and the fourth line of the Diagnostic Code has the following values, the symptom corresponds to this problem.
1) Fourth byte: the leftmost (x80) bit is 0 (any of 0*, 1*, 2*, 3*, 4*, 4*, 6*, and 7*), and
2) Fourth byte: the seventh (x02) bit from the left is 0 (any of *0, *1, *4, *5, *8, *9, *c, and *d), and
3) Fifth byte: the leftmost (x80) bit is 0 (any of 0*, 1*, 2*, 3*, 5*, 4*, 6*, and 7*), and
4) Seventh byte:
For the PCI expansion unit firmware version 1120 or earlier: Any value

For the PCI expansion unit firmware version 1130 or later: the leftmost (x80) bit is 0 and the second (x40) bit from the left is 0 (any of 0*, 1*, 2*, and 3*).

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 30 seconds before reconnecting 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 active replacement of the PSU, use the ioxadm(8) command. Note that the fieldeng privilege is required to execute the ioxadm(8) command.
