v The server supports one optional ultra-slim SATA CD-RW/DVD-ROM opticaldrive.v The server can support up to eight 2.5-inch hot-swap SAS/SATA drives, four3.5-inch hot-swap SAS/SATA drives, or four 3.5-inch simple-swap SATA drives.(see Supported SAS/SATA drive backplane configurations for the supportedconfigurations).v You can mix hot-swap SAS and SATA hard disk drives in the same server aslong as you do not mix drives on the same array.v The electromagnetic interference (EMI) integrity and cooling of the server areprotected by having all bays and PCI Express slots covered or occupied. Whenyou install a drive, save the EMC shield and filler panel from the bay in theevent that you later remove the device.Installing a 2.5-inch hot-swap hard disk driveThe following notes describe the types of hard disk drives that the server supportsand other information that you must consider when you install a hard disk drive:v Depending on the model, the server supports up to eight or up to sixteen2.5-inch SAS/SATA hot-swap hard disk drives in the hot-swap bays.Note: When using ServeRAID adapter M1015 to support more than sixteen2.5-inch hard disk drives, the maximum number of RAID supported drives is 16.All the other drives will remain JBOD (the drives are presented to the operatingsystem without a RAID configuration).v For a list of supported optional devices for the server, see http://www.ibm.com/servers/eserver/serverproven/compat/us/v Inspect the drive and drive bay for signs of damage.v Make sure that the drive is correctly installed in the drive bay.v See the documentation for the ServeRAID adapter for instructions for installinga hard disk drive.v All hot-swap drives in the server must have the same throughput speed rating;using drives with different speed ratings might cause all drives to operate at thespeed of the slowest drive.v You do not have to turn off the server to install hot-swap drives in the hot-swapdrive bays. However, you must turn off the server when you perform any stepsthat involve installing or removing cables.To install a 2.5-inch hot-swap hard disk drive, complete the following steps:1. Read the safety information that begins “Safety” on page vii and “Installationguidelines” on page 36Attention: Static electricity that is released to internal server componentswhen the server is powered-on might cause the server to halt, which mightresult in the loss of data. To avoid this potential problem, always use anelectrostatic-discharge wrist strap or other grounding system when you workinside the server with the power on.2. Unlock the left-side cover.Note: You must unlock the left-side cover to open or remove the bezel. Whenyou lock the left-side cover, it locks both the cover and the bezel.3. Open the bezel (see “Removing the bezel” on page 331)4. Remove the filler panel, if one is present.70 System x3300 M4 Type 7382: Installation and Service Guide
