POWER CORD SET

REQUIREMENTS

The voltage select switch feature on the computer permits it to operate from any line voltage between

100-120 or 200-240 volts AC.

The power cord set received with the computer meets the requirements for use in the country where

you purchased the equipment.

Power cord sets for use in other countries must meet the requirements of the country where you use

the computer. For more information on power cord set requirements, contact your authorized

Compaq dealer, reseller or service provider.

General Requirements

The requirements listed below are applicable to all countries:

1. The length of the power cord set must be at least 6.00 feet (1.8 m) and a maximum of 9.75 feet

(3.0 m).

2. All power cord sets must be approved by an acceptable accredited agency responsible for

evaluation in the country where the power cord set will be used.

3. The power cord set must have a minimum current capacity of 10A and a nominal voltage rating

of 125 or 250 volts AC, as required by each country’s power system.

4. The appliance coupler must meet the mechanical configuration of an EN 60 320/IEC 320

Standard Sheet C13 connector, for mating with appliance inlet on the Switch Box.

NOTES:

1. The flexible cord must be <HAR> Type HO5VV-F, 3-conductor, 1.0 mm2 conductor size. Power

cord set fittings (appliance coupler and wall plug) must bear the certification mark of the agency

responsible for evaluation in the country where it will be used.

2. The flexible cord must be Type SJT or equivalent, No. 18 AWG, 3-conductor. The wall plug

must be a two-pole grounding type with a NEMA 5-15P (15A, 125V) or NEMA 6-15P (15A

250V) configuration.

3. The appliance coupler, flexible cord, and wall plug must bear a "T" mark and registration number

in accordance with the Japanese Dentori Law. The flexible cord must be Type VCT or VCTF,

3-conductor, 0.75 mm2 conductor size. The wall plug must be a two-pole grounding type with a

Japanese Industrial Standard C8303 (15A, 125V) configuration.

appendix C

HARD DRIVES

Compaq Computer Corporation uses IDE hard disk drives that conform to two different

primary/secondary implementations. These are Conner mode and ATA-compatible mode. These two

modes are incompatible with one another.

If installing a second Ultra ATA hard drive on the primary controller, you must use an 80-conductor

ATA cable for optimal performance.

Device 0/Device 1 Relationship

A device 0/device 1 relationship exists when there are two hard drives connected to a single port. In

this situation, one drive must be designated as the device 0, or primary drive and the other as the

device 1, or secondary drive. This designation is necessary because both drives cannot work

simultaneously.

Cable Select

The Compaq Deskpro 4000 Series of Personal Computers use cable-select technology for identifying

Device 0 (primary) and Device 1 (secondary) IDE hard drives. Check that the jumpers on the IDE

hard drives are set properly for cable-select installation. Always check the label on the drives or

check Chapter 7 of this manual when a new drive is added to verify that the jumper settings are set

correctly.

 Cable select may not function properly if drives other than those supported by Compaq are

installed.

 The second drive on a cable-select cable can be a CD-ROM drive. However, the CD-ROM drive

must be installed in the device 1 position if a hard drive is installed on the same cable. Ensure

that both drives are set for cable-select configuration. See Chapter 7 for more information.

 If two drives are already connected to the primary IDE controller and an additional drive is to be

installed, the secondary IDE controller must be enabled. The secondary IDE controller can be

enabled by checking this option after opening the Advanced box in the Mass Storage group of

F10 Computer Setup. See Chapter 8 for more information.

 When more than two drives are installed, drive performances are best when the two faster drives

are connected to the primary IDE controller and the slower drive is connected to the secondary

IDE controller.
