Considerations

Bay A comes with one 3.5-inch, 1.44MB diskette drive in A2 and a CD-ROM in A1.

Bay B supports two 5.25-inch, or 3.5 inch half-high, removable-media devices.

Bay B also supports a disk drive in a special carrier when bays C, D, and E are

configured with SSA disk drives or SCSI RAID disk drives.

You cannot install hot-swappable drives in bays A or B.

Banks C, D, and E can accommodate six slim-high drives or three half-high drives, or

a combination of both drive sizes. If you use a combination, remember that one

half-high drive uses the equivalent space of two slim-high drives.

Your system supports eighteen 3.5-inch, slim-high (1.0 inch), disk drives or nine

3.5-inch, half-high (1.6 inch) disk drives in the bottom three banks (C, D, and E) or a

combination of slim and half-high drives.

Before installing disk drives in bank D and E, you must order disk drive backplanes

for bank D and E. Depending on your configuration, you may need to order and

install up to two additional SCSI-2 adapters. The internal Ultra SCSI option is

supported in backplanes C, D, and E and requires one Ultra SCSI adapter per bank.

The internal Serial Storage Architecture (SSA) option is supported in backplanes C,

D, and E and requires one SSA adapter that supports all three banks. To order,

contact your authorized reseller or marketing representative.)

Hot Swap Drives

The hot-swap backplane contains logic that allows you to remove disk drives without

turning off system power. The base system has a hot-swap backplane installed in

bank C. You can install six hot-swappable disk drives into the bays in bank C. You

can order additional hot-swap backplanes for banks D and E. Banks C, D, and E

each contain six bays. You can install up to six disk drives in bank C, bank D, or

bank E.

Attention: Proper procedures must be followed whenever you remove a disk drive.

Hot swap capability is available only with hot swap backplanes, and hot swap

carriers for the disk drive.
