v You can install two additional 5.25-inch, half-high, removable-media drives or one
additional 5.25-inch, full-high, removable-media drive in the removable-media
drive bays (A and B). The server supports full-high and half-high DLT, SDLT, and
LTO drives. For a list of supported options for your server, go to
http://www.ibm.com/pc/us/compat/ on the World Wide Web.
A three-drop power signal cable and a one-drop IDE cable come attached to the
CD-ROM drive. Use this power signal cable to connect the removable-media
drives. The one-drop SCSI signal cable that comes with your server will need to
be replaced with a two-drop SCSI signal cable to provide a signal connection to
the removable-media drives.
v You cannot install hot-swap drives in the removable-media or non-hot-swap drive
bays on the front side of the server, unless you install the 3-Pack Ultra320
Hot-Swap Expansion option.
v Your server supports a maximum of six 1-inch (26 mm) slim-high, 3.5-inch,
hot-swap hard disk drives in the standard hot-swap bays. In the tower model, the
hot-swap bays are arranged vertically in the standard hard disk drive cage; the
bay numbers are 0 through 5 (from bottom to top). In the rack configuration, the
hot-swap bays are arranged horizontally in the standard hard disk drive cage; the
bay numbers are 0 through 5 (from left to right). In the tower model, bays 0
through 5 are below the removable-media drive bays. In the rack configuration,
bays 0 through 5 are to the left of the removable-media drive bays.
Notes:
1. To minimize the possibility of damage to the hard disk drives when you are
installing them in a rack configuration, install the server in the rack before
installing the hard disk drives.
2. You do not have to turn off the server to install hot-swap drives in the hot-swap
drive bays. However, you must turn off the server when performing any steps
that involve installing or removing cables.
3. You can install three additional hot-swap hard disk drives in the server after you
install the 3-Pack Ultra320 Hot-Swap Expansion option (see “Working with the
3-Pack Ultra320 Hot-Swap Expansion option” on page 67). These drives are in
the optional hard disk drive cage. The SCSI IDs are listed in Table 8 on
page 107.
4. Some filler panels might come with a slim filler.
