Well, this is interesting. Mine doesn't appear to have an alarm, and these blog posts seem to indicate the same thing: http://msmvps.com/blogs/onq/archive/2007/03/17/it-doesn-t-what.aspx http://msmvps.com/blogs/onq/archive/2007/03/30/on-dell-s-perc-5-i.aspx Al From: Tom Rockwell [mailto:[log in to unmask]] Sent: Monday, July 25, 2011 3:24 PM To: Al Puzzuoli Cc: [log in to unmask] Subject: Re: [MSUNAG] Replacement RAID card with Audible Alarm for Poweredge 2950? It should have an audible alert http://support.dell.com/support/edocs/software/svradmin/5.1/en/omss_ug/html/apndx.html#1635831 That said, email alerts from OMSA have a longer range than the builtin alarm. I'm not exactly sure of the compatibility of different controllers to replace the PERC 5/i, though I think that PERC 5/i, PERC 6/i, SAS 5/i and SAS 6/i all can go in the internal slot in a 2950 and provide varying features. -Tom On 7/25/11 3:04 PM, Al Puzzuoli wrote: Hi everyone, Looks like we need to replace the RAID controller in our poweredge 2950. The unit currently has a PERC 5/I, which apparently has no audible alarm. I would like to upgrade to a controller that does in fact have an alarm, but I'm not sure which make or models to consider.
