Introduction

Product Description

This manual contains installation and troubleshooting information for the HP

27115A Fiber-Optic Link (HP-FL) device adapter.

The

HP

27115A HP-FL device adapter provides the computer system with a high speed, serial connection to peripheral devices over a fiber-optic data link. Device specific data are converted to a format compatible with the CIO bus

(cm), and then passed to the host computer. The channel adapter controls the

flow

of

traffic between the cm and the memory/processor bus. See figure 1-1.
