Quadrics QsNetII Interconnect

ERROR PSU X has missing Mains Input Good bit.
ERROR PSU X has missing 48V DC Good bit.
• Location: Main supply not within operational limits.
- Possible Diagnoses: See Table 12-1.
• Location: Output Voltage of PSU not within limits.
- Possible Diagnoses: See Table 12-1.
ERROR PSU X Fan Fail
• Location: Specified PSU fan.
- Possible Diagnoses: Fan obstruction.
Correction: Remove the obstruction from the specified power
supply fan.
Table 12-1 provides additional information for problems specific to the power
supply.

General PSU status bit error report
PSU alarm reported Examine the PSU front panel LED’s.
If the LEDs indicate the same failure,
suspect a faulty PSU.
Replace the PSU and re-test.
ERROR PSU psu_id has error bit bit_id
Review the PSU-specific
error and solutions first.
QM503 PSU status fault. Replace QM503 and re-test.
AC/DC wiring loom fault.
Midplane wiring loom fault.
Midplane fault associated with PSU
status line input to active QM503.
Replace chassis enclosure.
12.2 Environmental and Status Monitoring
To verify operational parameters, such as the temperature of components, and
functional parameters, such as the status of a link, you can use a software script.
You can also optionally run a series of manual checks and test commands as
described in the following sections:
• Run
qsnetstat to verify all modules in all interconnects, (see Section 12.2.1).
• Optionally, performing the following manual tests:
- Use the jtest command to check all (or individual) interconnects, see
(Section 12.2.2).
- Verify the common clock source, (see Section 12.2.3).
- Verify the view of the network, (see Section 12.2.4).
12.2.1 Using qsnetstat to Verify all Interconnects and Modules
To verify that the interconnect modules provide a consistent and valid network,
run the qsnetstat script as follows:
cp6000sms# /usr/bin/qsnetstat
