Diskette Drive; Hard Drive - NEC PowerMate Professional 9000E Series Service Manual

External connectors on the system board include two serial connectors, a
parallel connector, a keyboard port, mouse port, a LAN connector, and a serial
port. The second serial port is available on an expansion bracket. The system
board supports two USB ports; the connectors are located on an expansion
bracket.
The system board supports two diskette drives, up to four IDE devices such as a
hard drive, CD-ROM drive, and Zip drive, and up to seven SCSI devices.
The system board conforms to the AT form factor, and has an ATX 2.01
compliant I/O.
For further information on the system board, see Section 4, "System Board."
Section 6, "Illustrated Parts Breakdown" lists the NEC CSD part number for the
system board.

Diskette Drive

Two diskette drives are supported in the system. The installed 1.44-MB 3 1/2-
inch diskette drive is connected by a single ribbon cable with three connectors.
The diskette drive cable plugs directly into the system board. There are no
switches or jumpers that need to be set and the diskette drive is terminated.
Connector locations for the diskette drive on the riser board are given in
Section 4, "System Board." Section 6, "Illustrated Parts Breakdown," lists the
NEC CSD part number for the diskette drive. Diskette drive specifications are
given in Section 10, "Specifications."

Hard Drive

All systems ship with at least one internal 3 1/2-inch hard drive in the drive
cage. The drive cage supports up to four 1-inch high thin-height devices, or
three 1.6-inch high devices. IDE hard drives are available in 8.4-GB and
14.4-GB models. SCSI hard drives are available in 4.55-GB and 9.1-GB models.
The system board has two IDE/PCI interface connectors (primary and
secondary) for connecting IDE devices. In systems with an IDE hard drive, a
three-connector cable connects to the IDE hard drive and the primary connector
on the system board. Each connector supports up to two IDE devices.
A second IDE hard drive can be added to the primary channel. If the second
hard drive is installed, it connects to the middle connector on the IDE cable.
Systems come with two 3-connector IDE interface cables. If one of the cables is
not used, it is provided with the system but not connected.
In systems with a SCSI hard drive, a six-connector LVD SCSI cable connects
the drive to the internal SCSI connector on the SCSI adapter board.
Connector locations for the IDE and SCSI connectors on the system board are
given in Section 4, "System Board." Section 6, "Illustrated Parts Breakdown"
lists the NEC CSD part numbers for the hard drives. Hard drive specifications
are given in Section 10, "Specifications."
