Installing Internal Drives
Your PC Server 704 comes with one SCSI CD-ROM drive and
one 3.5-inch, 1.44 MB diskette drive.
The upper-left front bays support half-high, removable-media
drives.
Notes:
1. Installing hard disk drives in the upper-left front bays is not
recommended. The hard disk drives generate EMI. In
addition, hard disk drives in these bays are more susceptible
to ESD.
2. The server's EMI integrity and cooling are both protected by
having the upper-left front bays covered or occupied. When
you install a drive, save the filler panel and EMI shield from
the bay, in case you later remove the drive and do not
replace it with another.
You cannot install hot-swap drives in the upper-left front bays.
Your server supports twelve 3.5-inch, half-high, hot-swap hard
disk drives in the hot-swap bays. When you install drives in
these bays, install the first drive in the top left bay and proceed
with a left-to-right, top-to-bottom pattern.
The hot-swap bays connect to two SCSI backplanes. The
backplanes are the printed circuit boards behind the bays. Each
backplane supports up to six hard disk drives.
If you want to upgrade your server by installing a PCI RAID
adapter, an 8-bit SCSI cable (the PC Server 4-Drop SCSI Cable)
is available as an optional feature.
If you upgrade your server and you want to install 16-bit
devices, you might need a 16-bit cable. To order cables, contact
your IBM reseller or IBM marketing representative.
Note: Before you remove a hard disk drive, back up all data.
