1 DECrepeater 90FS Installation and Configuration
Introduction
The DECrepeater 90FS (also referred to in this manual as the module) is an Ethernet
repeater that provides two external 10BaseFL fiber-optic ports and one external AUI
port.
In this manual, the term 10BaseFL refers to the International Standards Organization
(ISO) 8802-3/ANSI/IEEE 802.3 fiber-optic local area networks (LAN) standards.
In this manual, the term Ethernet is Digital’s term for its product compatibility with the
ISO 8802-3/ANSI/IEEE 802.3 standards and the Ethernet standards for Carrier
Sense Multiple Access with Collision Detection (CSMA/CD) LANs.
To give your workgroup LAN media flexibility and connectivity, the module can be
configured into a DEChub 900 MultiSwitch (also referred to in this manual as the
DEChub 900), into a DEChub 90, or as a standalone unit. One or more (up to eight)
can be installed into a DEChub 900.
When installing the module into a DEChub 900 or in a DEChub 90, the module’s
hot-swap capability allows you to install or remove the module without turning off
power.
The module provides a side panel ThinWire port connector, used when the module is
installed as a standalone unit. The module provides a ThinWire port connection to
the backplane when the module is installed in a DEChub 900 or a DEChub 90.
The module’s front panel provides two fiber-optic ports that can operate
independently or as a redundant pair, and one attachment unit interface (AUI) port.
The front panel also provides light-emitting-diodes (LEDs) that indicate the status of
the module, the ports, and the network.
The module includes a serial port on the front panel that can be used as an
installation setup port when the module is installed into a DEChub 90 or installed as a
standalone unit. Using the setup menu, you can enable the module’s front panel
serial port for Out-of-Band Management (OBM).
NOTE: When the module is installed in a DEChub 900, you
must use the Hub Manager setup port on the DEChub
900 instead of the module’s setup port.
