The PCI FDDI Adapter Overview
The PCI FDDI adapter is a high-speed network link offering both
single-attach connections and dual attach connections to a Fiber
Distributed Data Interface dual-ring network that complies with the
ANSI standards (ANSI X3T9.5) for FDDI. This product consists of a PCI
FDDI adapter and its driver, developed by Hewlett-Packard. The current
PCI FDDI adapter is Hewlett-Packard part number A3739B. It supports
dual voltage 3.3 and 5 volts. The A3739B adapter card is not supported
on workstations earlier than B1000, C3000, and J5000. The previous
PCI FDDI adapter version A3739A is a 5 volt card, which has been
obsoleted, but still fully supported by the 11i operating system.
The PCI FDDI adapter can be connected directly to adjacent stations on
a dual-ring network or to a concentrator. It is customer-installable on
any class system supporting PCI except V-Class and Superdome, and
supports the standard HP link tools on all of the systems.
The PCI FDDI adapter uses fiber optic cables, and SC connectors. The
dual-attachment can be run in single-attach mode by connecting one
cable.
FDDI Concepts
The Fiber Distributed Data Interface (FDDI) is a high speed local
area network, defined by the standard from the American National
Standards Institute committee, ANSI X3T9.5 and by ISO. The FDDI
interface (single or dual) can be implemented with Fiber Optic or
Unsheilded Twisted-Pair cabling.
NOTE The HP implementation of the PCI FDDI interface is Fiber Optic only.
