Technical Information
CD-ROM READER
Some PowerMate Enterprise desktop systems come with a 24X CD-ROM reader. The
reader features up to 24-speed technology, allowing data to be transferred at up to 3600
KB/second, affording faster data transfer and smoother animation and video. The CD-ROM
reader comes with an Enhanced IDE (EIDE) interface. The reader is fully compatible with
Kodak Multisession Photo CDs™, CD-I, FMV, and CD Plus, as well as standard CDs. If
the system has sound (either on the system board or with the addition of an expansion
board) and speakers, the CD-ROM reader can also play audio CDs.
A three-connector device cable connects the reader to the secondary IDE/PCI port on the
riser board. The reader is connected as the master device on the secondary port. An
optional second device can be added to the secondary channel using the free connector on
the three-connector cable.
Specifications for the CD-ROM reader are given in Table 1-27 through Table 1-29.
CD-ROM jumper settings are included in Appendix B. Section 5 in this manual lists the
NECCSD part numbers for the CD-ROM readers.
PCMCIA DEVICE
Some systems come with a PCMCIA unit (or PC Card Host). The PCMCIA unit provides
twin PC card slots, which support two Type I/II cards, or one Type I/II card and one
Type III card. The unit supports ISA Plug and Play, and allows cards of mixed voltage to
be used in the same system. PC cards can provide the system with memory, storage,
fax/modem capabilities, video capabilities, or a serial port interface. The PCMCIA driver
enables full floppy disk or hard disk emulation on flash cards; compatible with all
compression and PC-utilities software.
The unit is comprised of a "SwapBox" housed in a 5 1/4-inch accessible slot, a PCMCIA
ISA adapter card, and a dual cable that connects them on the PCMCIA bus. PCMCIA
device specifications are given in Table 1-36.
TAPE BACKUP UNIT
Some systems come with a tape backup unit. The tape backup unit is a high-capacity, high-
performance data storage device that can compress and write data to and read and
uncompress data from tape. The unit also comes with backup software used to tailor the
backup process so that some or all of the files on the system can be backed up to a tape
cartridge. Files backed up to a tape backup unit are compressed to conserve space and to
speed up the backup process.
The tape backup unit is installed in a 5 1/4-inch accessible slot. The installed tape backup
unit is connected to an IDE cable that connects to the system board. The PCI/IDE channel,
and the master/slave configuration of the unit depend on the specific configuration of the
system. Tape backup unit specifications are given in Table 1-37.
