Appendix C
Hard Disk Drive Specifications and
Jumper Settings
This appendix provides specifications and jumper settings for the Western Digital 635-MB,
and 1.2-GB hard disk drives used in the PowerMate Ve series computer configurations.
Table 1-1 and Table 1-2 in Section 1 identifies which hard disk drives ship in which
configurations.
The standard IDE hard disk drives are mounted in the bottom front slot of the chassis. The
drive is connected via a two-connector IDE cable to the primary IDE channel on the system
board. The hard drive is set as the master device on the primary IDE channel.
The drive is auto-configurable, meaning that once the master/slave jumpers are set, the
hard disk type is automatically detected by the system and the remaining drive parameters
are automatically set by the system. (See Section 2, Setup and Operation, for information
on auto setup using the Autotype Fixed Disk parameter.)
NEC part numbers for the hard drives are provided in Section 5, System Unit Repair.
