https://community.hpe.com/t5/disk-enclosures/rack-storage-12/m-p/3599953#M17154 Hello, William.<BR /><BR />Here's a link to the maintenance guide for the rs/12. If it's a disk LED that is red, you have a problem with a disk. If it's a chassis LED, you have a problem with a component (PS, SCSI card, Management card) within the chassis.<BR /><BR /><A href="http://h200007.www2.hp.com/bc/docs/support/SupportManual/lpn11640/lpn11640.pdf" target="_blank">http://h200007.www2.hp.com/bc/docs/support/SupportManual/lpn11640/lpn11640.pdf</A><BR /><BR />Good Luck - Tim Tue, 09 Aug 2005 17:20:11 GMT timmy b. 2005-08-09T17:20:11Z https://community.hpe.com/t5/disk-enclosures/rack-storage-12/m-p/3599952#M17153 Hi I have a rack storage system/12 .<BR />The problem , is working fine but the customer complaint that the lights are flishig red .<BR /><BR />There is some time that I read about there is necessary apply a firmware update , <BR /><BR />Some idea about that <BR /><BR /><BR />Thank you <BR /><BR />W.S Tue, 09 Aug 2005 16:17:59 GMT https://community.hpe.com/t5/disk-enclosures/rack-storage-12/m-p/3599952#M17153 WilliamSmith11 2005-08-09T16:17:59Z https://community.hpe.com/t5/disk-enclosures/rack-storage-12/m-p/3599953#M17154 Hello, William.<BR /><BR />Here's a link to the maintenance guide for the rs/12.
