PORTswitch 900FP Description
Overview
Introduction
This chapter describes the features and components of the
PORTswitch 900FP.
The PORTswitch 900FP (also referred to in this manual as the module)
is a 12-port, 10BaseFL, fiber-optic, Ethernet repeater.

Module Features
Introduction
This section lists the features of the PORTswitch 900FP module.
How to Configure the Module
To give your workgroup LAN media flexibility and connectivity, you can
configure the module into a DEChub 900 MultiSwitch (also referred to in
this manual as the DEChub 900). You can install one or more
PORTswitch 900FP modules (up to 8) into the DEChub 900. The module
can also serve as a standalone unit when configured with a DEChub
ONE1docking station (see the
DEChub ONE Installation
manual).
Hot-swap Capability
When the module is installed into a DEChub 900 or into a DEChub
ONE, the module's hot-swap capability allows you to install or remove
the module without turning off power.
Front Panel
The front panel provides 12 fiber-optic ports that can operate
independently on one LAN or can operate as up to 6 separate port pairs.
The port pairs can be assigned independently to any of six backplane
LANs. In addition, using HUBwatch or any SNMP-based management
tool, you can assign the port pairs as redundant links to other devices.
The front panel also contains light-emitting diodes (LEDs) that indicate
the status of the module, the ports, and the network.
1In this manual, the term DEChub ONE refers to the DEChub ONE or
to the DEChub ONE-MX docking station unless otherwise specified.
