Recycle carrier (demand only, Test #1534)
The recycle carrier command is useful for three different troubleshooting actions:
● To verify that a redundant power supply can carry the full load. This is done by issuing the
SAT command recycle carrier location with the slot number of the power supply
that is to be momentarily shut down.
Each power supply monitors the voltage on the backplane and not the voltages from the
power supply itself. Therefore, when redundant power supplies are present, the only way to
check the voltages from each power supply is to use the recycle power supply command
with the slot number chosen to force the other power supply to be tested when it is the only
supply on the backplane.
● To momentarily shut the power off for an entire carrier to force all the boards in the carrier
to be power cycled. This is done by issuing the SAT command recycle carrier
location.
Note:
Note: When redundant power supplies are present, this test may generate error log
entries for either power supply in the carrier.
● To momentarily shut the power off for a control carrier to force the EPN to go down and
back up with a COLD restart. This is done by issuing the SAT command recycle
carrier location override for a G650 carrier with an active IPSI.
For the case where duplicate IPSIs are present in a port network, the set ipserver
command can be used to put an IPSI in the standby mode, so that a recycle of the carrier
containing that IPSI will not cause a reset of the EPN.
The following test results may be obtained from the recycle carrier command:
Note:
Note: It is unlikely that failure codes 1 or 2 will occur when redundant power supplies
are present, because each power supply is measuring the backplane voltage
instead of the power supply voltage.
Failure
Code
Description
1 Output voltages for the power supply under test are out of tolerance after the
power was restored.
2 When redundant power supplies are present, the output voltages for the other
power supply are out of tolerance after the power was restored.
16 When redundant power supplies are present, and the slot number is specified,
the output voltages for the other power supply are out of tolerance during the
time that power supply is the only power supply providing power.
If it is acceptable to disrupt service temporarily, remove the good power supply
and run test board for the other power supply to verify that it has failed.
