觉得该是10u的电源坏的可能性较大作者: 2000www 时间: 2004-12-14 12:28 标题: 又来临时抱佛脚了,请教s7a电源问题 说错了,如果是i/o柜电源的话,7U的必须宕机,因为其两个电源都是工作的非冗余。
“cpu柜的内部是5+1的直流电源模块”这句话不太理解,小时物理没学好。作者: 纳闷 时间: 2004-12-14 12:47 标题: 又来临时抱佛脚了,请教s7a电源问题 书上翻来的吧,说得不好,原话如下,摘自7017-s70 service guide
The filtered 200-240 V ac is then sent to the six system bulk power supplies. The
six supplies are coupled together and provide an N+1 level of redundancy for protection.
N+1 refers to the fact that since the supplies are coupled to a common distribution
bus, if one of the six supplies fails, the system will not fail. The bulk
supplies provide a positive 29 volt output which is fed to the system regulator located
above the bulk supplies and to the system blowers.作者: 纳闷 时间: 2004-12-14 13:02 标题: 又来临时抱佛脚了,请教s7a电源问题 至于7u的必须宕机,并不全对,左边3/4的电源供给media bay,右边1/4的电源供给hot swap disk drive bay,磁带机和光驱断电并不会导致宕机
严谨的说,电源报错也并不等于电源没有工作作者: 2000www 时间: 2004-12-14 13:23 标题: 又来临时抱佛脚了,请教s7a电源问题 多谢,多谢,看来我以后应该养成多看资料的习惯,了解设备及系统架构,做到象你这样,有备无患。作者: 纳闷 时间: 2004-12-14 13:52 标题: 又来临时抱佛脚了,请教s7a电源问题 作者: 2000www 时间: 2004-12-14 13:53 标题: 又来临时抱佛脚了,请教s7a电源问题 刚才与客户负责这方面的人联系上了,按他说的意思应该是10U的他说前一段已经试过了,一直开机的情况,两个电源里有一个灯不亮了,风扇也不转了,应该是辙底坏了,他说这个10U的柜子里加的东西不多,开机很麻烦,直接拨走修去就行了。这样可以吗?作者: 纳闷 时间: 2004-12-14 14:53 标题: 又来临时抱佛脚了,请教s7a电源问题 应该问题不大,我的5分钟说法欠妥,是参照S80的I/O柜的作者: 2000www 时间: 2004-12-14 15:55 标题: 又来临时抱佛脚了,请教s7a电源问题 再次感谢,唉没办法,以前一直做别的项目,关于aix方面的没有系统的做过,现在赶鸭子上架,但是维护这方面都是客户重要的数据,大概知道怎么做了,但是总是心里没谱,只能求教各位坛子里的朋友了。作者: ar6400 时间: 2004-12-14 18:26 标题: 又来临时抱佛脚了,请教s7a电源问题 10U:拔下坏模块后,必须在5分钟之内插入新电源模块,或空电源模块.
5分钟的时间包括换风扇的时间。超时会宕机。
Power Supplies and Power Supply Fan Assemblies (10 EIA-Unit I/O Drawer)
Notes:
1. The 10 EIA-Unit I/O Drawer can hold up to two power supplies. You can replace each supply separately. The removal and replacement procedures are the same for each power supply.
2. If the I/O Drawer has two power supplies and only one needs to be removed, you do not have to power down the system.
3. Each power supply has a test switch. See “Power Supply Test Switch Procedure (10 EIA-Unit I/O Drawer)” on page 9-43.
4. If your system has only one power supply, the unused power supply position must be filled with a power supply blank, which must have a power supply fan assembly attached to it.
5. You need a 6mm nutdriver to perform this procedure.
Removal DANGER
Do not attempt to open the covers of the power supply. Power supplies are not serviceable and are to be replaced as a unit.
Attention: Do not perform the hot-swap procedure for a power supply if the ambient temperature is greater than 32°C (90°F), as it can cause loss of data or data corruption.
Be sure that the replacement power supply is ready to install, as the 10 EIA-Unit I/O Drawer can encounter problems if the power supply is removed for longer than five minutes.作者: 2000www 时间: 2004-12-14 18:44 标题: 又来临时抱佛脚了,请教s7a电源问题 谢谢,我刚才刚刚看到pdf文档的第528页,的确是说如果超过五分钟会出现问题的。作者: 纳闷 时间: 2004-12-15 00:24 标题: 又来临时抱佛脚了,请教s7a电源问题 呵呵,谢谢指正,
文档看得不够仔细
