QuickSwitch® Model 4184 Fiber Optic SC Duplex 100BASE-FX A/B Switch with Remote Port
Overview
QuickSwitch® 4184 is a fiber optic SC Duplex Interface A/B
Switch. It has a multimode duplex fiber connector interface on the A,
B, and COMMON ports. The switch connects a workstation or network
between two other devices or networks. The internal circuitry insures
isolation between the A and B devices / networks. A great solution for
fallback network applications. A front panel button changes the switch
position eliminating the need to plug and unplug fiber patchcords thus
minimizing connector wear. Switch position status is displayed on the
front panel LEDs.
The unit also includes an RS232 serial security enhanced Supervisory Remote Port. Upon proper authentication, a terminal or computer in terminal mode connected to this port can communicate with
the unit, determine its status, change the switch position as desired,
and/or lockout front panel switching capability. A modem can also be
connected to this port for remote access to the switch. Access to the
Supervisory Remote Port feature is password protected. An optional
graphical user interface (GUI) software is also available for use with a
computer running Windows operating system.
