Environmental Requirements

Table 3-5 lists environmental requirements for the tape drive module.

Fiber-Optic Cable Installation

You use the same kind of fiber-optic cable to attach a tape drive CRU to a 3216

controller or a 6761 fiber-optic plug-in card (F-PIC) on a 6760 adapter. Part numbers

for the different cable lengths are listed in Appendix A, Part Numbers. The procedures

in this section assume that the fiber-optic cable has been installed by a certified cable

installer. Within the U.S., installation support can be obtained through your service

provider. Services are available for virtually every aspect of the installation process,

including site survey, construction and safety permits, cable selection, installation,

terminations, and testing.

For an installation performed by personnel not employed by Compaq, your service

provider can certify that the minimum requirements are met for proper system

operation. To take advantage of these services, contact your service provider.

AC Power Requirements

Each 5190 and 5194 tape drive CRU contains an auto-ranging power supply that

accepts input current in two voltage ranges: 85–132 volts AC (3.0 amperes) and

170–264 volts AC (1.5 amperes). No switch is required to change between ranges or

between 50 and 60 hertz. Table 3-6 shows the tape drive CRU AC power

requirements.
