Cisco7609电源故障处理

昨天到机房发现Cisco7609风扇Output Power指示灯亮红灯,风扇不转。Log信息提示风扇坏,信息如下:
Mar 24 08:10:33 GMT: %C6KENV-SP-4-PSFANFAILED: the fan in power supply 2 has failed
Mar 24 08:10:33 GMT: %C6KPWR-SP-4-PSFAIL: power supply 2 output failed.
Mar 24 08:10:33 GMT: %C6KPWR-SP-4-PSREDUNDANTONESUPPLY: in power-redundancy mode, system is operating on one power supply.
Mar 24 08:15:42 GMT: %C6KENV-SP-4-PSFANOK: the fan in power supply 2 is OK
Mar 24 08:15:43 GMT: %C6KPWR-SP-4-PSOK: power supply 2 turned on.
Mar 24 08:15:43 GMT: %C6KPWR-SP-4-PSREDUNDANTBOTHSUPPLY: in power-redundancy mode, system is operating on both power supplies.


用sh env alarm命令查看系统告警信息如下:
show environment alarm
environmental alarms:
system minor alarm on power-supply 2 power-output-fail (raised 00:25:26 ago)

幸好设备买保了,就直接向Cisco开Case处理。

Cisco RMA了电源,换上去后正常一段时间,现在又有该问题了,LOG信息如下:
Jun 13 08:52:38: %C6KPWR-SP-4-PSFAIL: power supply 2 output failed.
Jun 13 08:52:38: %C6KPWR-SP-4-PSREDUNDANTONESUPPLY: in power-redundancy mode, system is operating on one power supply.
Jun 13 08:52:40: %C6KPWR-SP-4-PSOK: power supply 2 turned on.
Jun 13 08:52:40: %C6KPWR-SP-4-PSREDUNDANTBOTHSUPPLY: in power-redundancy mode, system is operating on both power supplies.

Jun 14 16:22:07: %C6KPWR-SP-4-PSFAIL: power supply 2 output failed.
Jun 14 16:22:07: %C6KPWR-SP-4-PSREDUNDANTONESUPPLY: in power-redundancy mode, system is operating on one power supply.
Jun 14 16:22:08: %C6KPWR-SP-4-PSOK: power supply 2 turned on.
Jun 14 16:22:08: %C6KPWR-SP-4-PSREDUNDANTBOTHSUPPLY: in power-redundancy mode, system is operating on both power supplies.

在Jun 13这天,从早上到晚上不断有告警,而Jun 14这天就一次告警,由此看来可能不是电源问题,而是这个电源槽位可能存在问题。 另外还有一种可能是这路电源存在问题。

于昨日将该告警的电源与另外一台7609的电源交换了一下,观察是电源问题,还是电源插槽问题。 同时仔细检查了一下配电是不是有问题,在检查中,发现电源插头一插片接触不良(做工太粗糙了),只好重新做了一个插头。 另外该电源在另外一台7609上还是出现了相同告警,如下:
Jun 18 09:29:01: %C6KPWR-SP-2-PSFAIL: power supply 2 output failed.
Jun 18 09:29:01: %C6KPWR-SP-4-PSREDUNDANTONESUPPLY: in power-redundancy mode, system is operating on one power supply.
Jun 18 09:29:03: %C6KPWR-SP-4-PSOK: power supply 2 turned on.
Jun 18 09:29:03: %C6KPWR-SP-4-PSREDUNDANTBOTHSUPPLY: in power-redundancy mode, system is operating on both power supplies.

看来,这个电源已经损坏。而且换过去的那个电源却无任何告警信息,得继续观察其运行情况。
通过上面的操作,我怀疑是插头问题导致供电不稳,从而损坏了电源。再观察几天基本上就可以得出结论了。
