The Hard Drive backplane supports either a SATADVD or a PATADVD, depending
on when it was manufactured. Servers that contain a SATA-compatiblebackplane
have a "SATA"label on the front bezel. Servers with the older PATA-compatible
backplanes do not have any DVD label on the bezel.
Note – SATA-compatiblebackplanes have special keying that prevents full insertion
of a PATADVD. When installing a PATA-typeDVD, do not force the module if it
resists full insertion. It may be that the backplane is not PATA-compatible.
