Table 1. Maximum Allowable Drive Sizes
Types of cables:
Drives connect to the server with
cables.
Each cable connector is designed to fit a
corresponding connector on a drive.
Three types of internal cables connect to the drives in the
server:
±
A four-wire power cable connects to each drive.
±
A flat-ribbon signal cable connects to IDE devices.
–
One flat-ribbon cable connects the internal
diskette drive.
The connector on one end of this cable attaches
to the system board.
The primary diskette drive
installed in the server (usually known as drive A)
is attached to the connector on the other end of
this cable.
Note
The primary diskette drive must always be
attached to the drive connector on the end
of this cable.
–
A second flat-ribbon cable connects the
CD-ROM drive.
This cable has two drive connectors.
A third
connector attaches to the system board.
The
CD-ROM drive that comes with the server is
attached to the connector on the end of this
cable.
±
Another cable connects internal SCSI devices.
This
SCSI cable has two connectors that connect to SCSI
devices:
–
One to the backplane of the DASD hot-swap
enclosure
