Installing Internal Drives
You cannot install hot-swap drives in bay B.
Your server supports eighteen 3.5-inch, slim-high, hot-swap
hard disk drives, or nine 3.5-inch, half-high hard disk drives in
the bottom three banks (C, D, and E).
Banks C, D, and E can accommodate six slim-high, hot-swap
hard disk 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.
If you install drives in bank D or E, you must remove the fan
assembly on the rear of the server, install a direct access storage
device (DASD) backplane in bank D or E, and add power and
internal SCSI cables. You must also have an additional power
supply, such as an optional 220-watt power supply or the IBM
PC Server 780W Redundant Power Option, installed by your
IBM service technician. (Instructions on removing the fan
assembly and installing a backplane are given in “Installing a
Drive in Bank D” on page 240.)
You might need to install an additional SCSI-2 adapter.
(Instructions are given in “Installing Adapters” on page 197.)
Each backplane has six connectors, to support up to six hard
disk drives.
An address jumper is located on the rear of each backplane. Set
the jumper as described in “Setting the Backplane Address
Jumper (J2)” on page 273.
A SCSI ID jumper (J12) is located on the rear of each backplane.
When you daisy-chain two backplanes, you must set the
jumpers on these backplanes as described in “Setting Backplane
SCSI ID Jumpers (J12)” on page 274.
If you are installing a drive in a hot-swap tray that has jumpers
(for example, ID jumper), remove the jumper pin block from the
drive.
