Replacing SAS Drive on Prolient ML350 with Smart Array P410i

Hello

I have a Prolient ML350 with two RAIDs Configured, see attached picture.

Each RAID has 1 faulty hard drive, the faulty drives show constant red LED's.

I bought 2 new SAS drives, which I thought were compatable, and do seem to fit, however they are not exactly the same as the original drives, as the new drives do not have status LEDS. 

I have fitted the drives, however the Array Configuration Utility does not seem to pick up the drives.

Please see the attached screenshot of the Array utility.

Links to the new drives:

Have I bought incompatable drives? or is there some other issue? The guide I have looked at all suggest that the server will automatically detect the new drives rebuild the array.

Any advise would be appreciated.

Thanks in advance
