Replacing a drive compatibility key
Each hard disk drive bay contains a drive compatibility key, which helps to ensure
that you install only a supported drive in the bay.
Important : Do not attempt to install any hard disk drive other than a supported
drive in any hard disk drive bay. See http://www.ibm.com/systems/storage/disk/
ds3000/ds3300/ for information about the DS3300 and an interoperability matrix that
lists supported hard disk drives.
If a drive compatibility key breaks, you must replace it. The miscellaneous hardware
kit contains several replacement drive compatibility keys; obtain a kit if you have to
replace a drive compatibility key (see Table 9 on page 106).
