Yes, it is possible that the optical drive is faulty. Review the hardware logs. Also enter the system BIOS setup using F2 key and check for devices listed as unknown.
Hi all, I recently replaced a non-redundant PSU on my Dell Poweredge R410. During troubleshooting I also temporarily removed the System Battery at one point. The server is operational again, but when booting up, I get: "Fan 4 speed may change depending on system configuration and option card install Strike the F1 Key to Continue, F2 to run the setup utility." I'm thinking that some BIOS setting got resets when removing the battery? I'm also seeing a lot of forum posts mentioning that the cause of this error is the embedded SATA being connected to nothing. My hard drives are connected to a PERC via the PCI slot, and the machine does have an optical drive. I can't see optical drive's existence in omreport. Here is some output from omreport regarding SATA settings. Embedded SATA Controller : ATASATA Port 0 : AutoSATA Port 1 : OffSATA Port 2 : OffSATA Port 3 : OffSATA Port 4 : Off Any advice on how to go about debugging this further? Thanks! Dave
